HMPSA77

The HMPSA77 belongs to the HMPSA series. It is a NPN epitaxial planar transistor which is made by the MICROELECTRONICS CORP. It is designed for application that requires high voltage. It is available in the TO-92 package.

There are some features as follows. (1) high breakdown voltage which is 400 V at IC is 1 mA; (2) high current gain; (3) complementary to HMPSA94.

The following is the description about its absolute maximum ratings at TA is 25 . (1): storage temperature is from -55 to 150 and the maximum junction temperature is 150 ; (2): total power dissipation is 625 mW when TA is 25 ; (3): collector to base voltage(BVCBO) is 400 V and collector to emitter voltage(BVCEO) is 400 V,emitter to base voltage(VBEBO) is 6 V; (4): IC collector current is 300 mA; (5): the minimum VBCBO is 400 V when IC 100 A and IE is 0 ; (6): the minimum BVCEO is 400 V when IC is 1 mA and IB is 0,and VBEBO is 6 V at IE is 10 A and IC is 0; (7): the maximum ICBO is 100 nA when VCB is 400 V and IE is 0,IEBO is 100 nA at VEB is 4 V and IC is 0,ICES is 500 nA when VCE is 400 V and VBE is 0; (8): the maximum VCE(sat) is 350 mV at the condition of IC is 1 mA and IB is 0.1 mA.
