onsemi 2SB764E-SSH-ON

Overview

2SB764E-SSH-ON from ON Semiconductor (formerly SANYO) is a PNP epitaxial planar silicon transistor designed for voltage regulation and relay/lamp driver applications in industrial electrical equipment. It features V_CEO = −50 V, I_C = −500 mA, P_C = 0.9 W, h_FE = 60–200 at I_C = −50 mA, and operates up to T_j = +150 °C.

For engineers reviewing the 2SB764E-SSH-ON datasheet, pinout, applications, or equivalent options, key selection criteria include its −50 V V_CEO, −500 mA continuous collector current, low V_CE(sat) of −0.5 V (I_C/I_B = 10), TO-92MP package compatibility, and suitability for DC load switching in power supply and control circuits.

Technical Context

This PNP bipolar junction transistor uses epitaxial planar construction for stable gain and consistent switching behavior across temperature. Its −50 V V_CEO and −500 mA I_C rating support medium-voltage, medium-current DC switching in discrete regulator and driver stages.

The device exhibits h_FE = 60–200 (measured at V_CE = −2 V, I_C = −50 mA), f_T = 150 MHz (V_CE = −10 V, I_C = −50 mA), and V_CE(sat) ≤ −0.5 V at I_C/I_B = 10 - confirming suitability for saturated-switching operation with minimal conduction loss.

FAQ

What is the maximum collector-emitter voltage rating for the 2SB764E-SSH-ON?

The 2SB764E-SSH-ON has a maximum collector-emitter voltage rating (V_CEO) of −50 V at T_a = 25 °C. This rating applies under open-base conditions and defines the upper limit for safe DC voltage differential between collector and emitter terminals. Exceeding this value risks avalanche breakdown and permanent device failure. Derating is required at elevated ambient temperatures per the absolute maximum ratings table.

Can the 2SB764E-SSH-ON be used as a direct replacement for the original SANYO 2SB764?

Yes, the 2SB764E-SSH-ON is the ON Semiconductor–branded continuation of the SANYO 2SB764, retaining identical electrical specifications, pinout (Emitter–Collector–Base), TO-92MP package dimensions, and thermal characteristics. The "E" suffix denotes enhanced reliability screening, and "SSH" indicates tape-and-reel packaging - both fully compatible with legacy 2SB764 designs.

What is the typical DC current gain (h_FE) of the 2SB764E-SSH-ON at operating conditions?

The 2SB764E-SSH-ON exhibits a DC current gain (h_FE) ranging from 60 to 200 when measured at V_CE = −2 V and I_C = −50 mA. This gain spread reflects factory binning; individual units are marked with gain group codes. For design purposes, h_FE ≥ 60 ensures reliable saturation with standard base drive resistors across process and temperature variations.

Does the 2SB764E-SSH-ON require a heatsink in normal operation?

The 2SB764E-SSH-ON does not require an external heatsink when dissipating ≤0.9 W at T_a ≤ 25 °C, as specified in its absolute maximum ratings. At higher ambient temperatures or continuous power levels above 0.5 W, PCB copper area (≥1 cm² per watt on inner layers) serves as sufficient thermal relief. Heatsinking becomes necessary only if P_C exceeds 0.7 W at T_a > 60 °C.

What are the recommended operating conditions for reliable long-term use of the 2SB764E-SSH-ON?

For reliable long-term operation, the 2SB764E-SSH-ON should be operated within its absolute maximum ratings: V_CEO ≤ −50 V, I_C ≤ −500 mA, P_C ≤ 0.9 W, and junction temperature T_j ≤ +150 °C. Derate power linearly above 25 °C ambient, maintain V_CB ≤ −60 V, and avoid transient overvoltage events exceeding rated values - even momentarily - as these may cause irreversible degradation.
