Nexperia has announced 20 bipolar power transistors in 2 x 2mm DFN2020D-3 packaging, half of them automotive-qualified. The span 50 and 80V ratings, 1 to 3A currents and both npn and pnp polarities. “DFN2020D-3 packaged devices deliver an 80% reduction in board space when compared to SOT89, and a 90% reduction compared to SOT223,” according to the company. “The package ...
There is some hogwash out there, masquerading as engineering white papers, which are really just click bait to get your contact details. And there are some gems available for the same price. And, in my opinion, ‘BJT. Bipolar junction transistor application handbook‘ from Nexperia is one of the gems. The price is handing over your name, company name and email ...
The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few dozen microamperes of current, allowing the devices to act as both a rectifier and current source in AC applications.” Which ...
First, an apology: This blog has been inactive for a while because covid reared its head again, and this time ‘brain fog’ was a feature, which led to getting nothing much done for a month or so…. Now the brain is back to some extent, I noticed a whole genre of transistor that I was ignorant of, and it seems ...
Ideal Power is aiming to compete with smart IGBT modules, with a 1.2kV 160A (100°C, 240A at 25°C) power module built around its novel ‘B-Tran’ bi-direction semiconductor switch. Called IPA01216DFx-HS, it comes in an industry-standard 62mm package which includes an isolated driver circuit and “has significant advantages compared to IGBT modules, including lower losses and inherent bidirectionality”, according to the ...
Ideal Power has launched the first commercial version of its novel bi-directional semiconductor power switch, a multi-die module rated at 1,200V 100A (25°C, 50A 100°C) aimed at solid-state circuit breakers (SSCBs) and matrix converters. Updated below to include driving requirements Called IPAM01210C10, “the power module was designed specifically to enable SSCBs to deliver very low conduction losses, while operating orders ...
Ash Madni, WIMMIC’s Technical Director, tells how his lifelong adventure in electronics began with the discovery of the world of Bipolar transistors, namely the BC108… It all started when I was 13 years old at school. A class mate was an Electronics hobbyist and during break, he talked animatedly about what he was going to build over the weekend. My ...
The holiday gave me a chance to play with bipolar transistor mosfet drivers again. And things did not go quite as planned. I had been using the circuit on the right quite happily from a signal generator. Rise time was quick enough with 470Ω for R3, and is did not have to resort to my improved version of the driver. ...
It is not often you see a new bipolar transistor introduced, and Nexperia has just revealed not just one, but nine of them. All in surface-mount DPAK (TO-252, SOT428C) packaging, they are intended for automotive (in AEC-Q101 qualified form) and industrial applications, and fill out the company’s MJD family to span 2 – 8A and 45 – 100V. The new parts ...
In a world of mosfets and hemts, it is not often you see a new pnp power transistor. Earlier this year, Diodes did just that, with some 2.5W dual pnp bipolars for switching automotive lighting – particularly matrix headlights – the soon-to-be realised headlights that change beam shape by projecting an image of a high-fill-factor square array of leds into ...
