PU3121

The PU3121 is designed as silicon NPN triple diffused planar type.

PU3121 has four features. The first one is it would have built-in 60V zener diode between C and B. The next one is it would have very small fluctuation in breakdown voltage. The next one is it would have high speed switching. The next one is it would have 3 NPN elements. That are all the main features.

Some absolute maximum ratings of PU3121 have been concluded into several points as follow. The first one is about its collector to base voltage which would be 30±5V. The next one is about its collector to emitter voltage which would be 30±5V. The next one is about its emitter to base voltage which would be 5V. The next one is about its peak collector current which would be 4A. The next one is about its collector current which would be 2A. The next one is about its power dissipation which would be 15W. The next one is about its junction temperature range which would be 150°C. The next one is about its storage temperature range which would be from -55 to +150°C.

Also there are some electrical characteristics of PU3121 having been concluded into several points as follow. The first one is about its collector cutoff current which would be max 100uA with condition of Vcb=25V and Ie=0. The next one is about its emitter cutoff current which would be max 2mA with condition of Veb=5V and Ic=0. The next one is about its collector to emitter voltage which would be min 25V and max 35V with condition of Ic=5mA and Ib=0. The next one is about its DC current gain which would be min 1000 and max 10000 with condition of Vce=4V and Ic=2A. The next one is collector to emitter saturation voltage which would be max 2.5V. The next one is about its transition frequency which would be typ 20MHz with condition of Vce=10V, Ic=0.5A and f=1MHz. And so on. For more information please contact us.
