Product details

Overview

2SB764F-AE from SANYO is a PNP epitaxial planar silicon transistor designed for voltage regulation and relay/lamp driver applications, with V_CEO = −50 V, I_C = −500 mA, h_FE = 60–200 at I_C = −50 mA, V_CE(sat) = −0.5 V (I_C/I_B = 10), and P_C = 0.9 W in TO-92MP package. It operates in industrial electrical equipment requiring medium-power switching.

For engineers reviewing the 2SB764F-AE datasheet, pinout, applications, or equivalent options, key selection criteria include its PNP polarity, −50 V V_CEO, −500 mA continuous collector current rating, DC current gain range, and TO-92MP thermal performance under ambient conditions up to +125°C junction temperature.

Technical Context

This device functions as a medium-power PNP bipolar junction transistor optimized for linear regulation and saturated-switching roles in discrete power control circuits. Its design supports stable DC current amplification (h_FE ≥ 60 at −50 mA) and low-saturation operation (V_CE(sat) ≤ −0.5 V) with base drive sufficient for relay coil and incandescent lamp loads.

The 2SB764F-AE uses epitaxial planar construction for consistent parameter distribution and reliability in non-safety-critical industrial equipment. It is not rated for life-support, aircraft control, or other ultra-high-reliability systems per SANYO's application disclaimer.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50 V: Maximum allowable collector-to-emitter voltage with base open; defines safe operating range in switching and linear regulator topologies.
I_C (max)	−500 mA: Continuous collector current limit; supports driving relays up to ~12 V/500 mA or lamps with comparable load profiles.
h_FE	60–200 at I_C = −50 mA: DC current gain range determines required base drive for reliable saturation in switching applications.
V_CE(sat)	−0.5 V (I_C/I_B = 10): Low saturation voltage minimizes power loss and heat generation during on-state operation.
P_C	0.9 W at T_a = 25°C: Total power dissipation capability; derates linearly above 25°C ambient, reaching zero at +150°C case temperature.
f_T	150 MHz at V_CE = −10 V, I_C = −50 mA: Gain-bandwidth product indicates usable frequency limit for small-signal amplification, not switching.
C_ob	21 pF at V_CB = −10 V, f = 1 MHz: Output capacitance affects switching speed and high-frequency stability in amplifier configurations.

Pinout & Package

2SB764F-AE is housed in the TO-92MP (SANYO MP) plastic package - a 3-lead through-hole variant with standardized lead spacing and thermal profile compatible with wave soldering. Dimensions match JEDEC TO-92 outline with 14.0 mm body length and 4.7 mm width.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current exit terminal for PNP device	Connected to higher potential rail (e.g., V_CC) in common-emitter switch; sets reference for base bias network.
2 (Collector)	Current entry terminal for PNP device	Typically tied to load (relay coil, lamp) and grounded return path; carries full switched current.
3 (Base)	Control input for minority-carrier injection	Receives current-limited drive signal (e.g., microcontroller GPIO via resistor); controls conduction state of collector-emitter path.

Feature	Design Value
PNP polarity with −50 V V_CEO	Enables high-side switching in positive-rail systems without level-shifting circuitry.
h_FE binning (60–200)	Supports predictable base resistor selection across production lots for consistent turn-on behavior.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP medium-power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SB772	V_CEO = −40 V, I_C = −500 mA, h_FE = 60–240, same TO-92MP package	Lower V_CEO limits use in 48 V systems or high-transient environments	Select when lower voltage rating is acceptable and wider h_FE spread supports looser base drive tolerance.
BC557B	V_CEO = −45 V, I_C = −100 mA, h_FE = 200–450, TO-92 package (not MP)	Lower current rating restricts use to sub-100 mA loads; different thermal resistance due to non-MP body	Choose only for low-current signal-level switching where gain consistency outweighs power handling.

Compared with 2SB764F-AE, the 2SB772 offers slightly higher h_FE but reduced voltage margin, while the BC557B trades current capacity and thermal robustness for tighter gain control-making the 2SB764F-AE optimal for 500 mA relay/lamp loads requiring −50 V standoff and proven TO-92MP reliability.

FAQ

What is the maximum collector-emitter voltage rating for the 2SB764F-AE?

The 2SB764F-AE has a maximum collector-emitter voltage rating (V_CEO) of −50 V with the base open. This rating defines the upper limit for safe operation in switching or linear regulator configurations. Exceeding this value-even momentarily-may cause irreversible device failure. The 2SB764F-AE must not be used in circuits where transient spikes or design margins could breach this absolute maximum rating.

Does the 2SB764F-AE support saturated switching for relay coil driving?

Yes, the 2SB764F-AE is specifically characterized for saturated switching: at I_C = −500 mA and I_B = −50 mA (I_C/I_B = 10), V_CE(sat) is guaranteed ≤ −0.5 V. This low saturation voltage ensures minimal power loss and thermal stress when driving typical 12 V relay coils. The 2SB764F-AE achieves reliable turn-on with standard base resistor networks referenced to microcontroller outputs or logic gates.

What package type does the 2SB764F-AE use, and is it compatible with standard TO-92 footprints?

The 2SB764F-AE uses the TO-92MP (SANYO MP) package-a variant of TO-92 with modified lead frame geometry for improved thermal performance and mechanical robustness. While pinout (Emitter-Collector-Base) matches standard TO-92, the TO-92MP has distinct dimensions (e.g., 14.0 mm body length) and thermal resistance. PCB footprints must conform to SANYO's MP specification, not generic TO-92 land patterns, to ensure reliable solder joint formation and thermal transfer for the 2SB764F-AE.

Can the 2SB764F-AE be used in linear voltage regulator designs?

Yes, the 2SB764F-AE is qualified for linear regulator pass element use, with verified performance at V_CE = −2 V and I_C = −500 mA in active region operation. Its −50 V V_CEO provides ample headroom for 12 V or 24 V input rails, and its h_FE stability supports predictable error amplifier feedback loop design. However, the 2SB764F-AE is not intended for life-support or aviation systems per SANYO's application disclaimer.

What is the junction temperature limit and thermal derating behavior of the 2SB764F-AE?

The 2SB764F-AE has a maximum junction temperature (T_j) of +150°C and a storage temperature range of −55°C to +150°C. Its power dissipation (P_C) is rated at 0.9 W at T_a = 25°C and decreases linearly to zero at T_a = +150°C. Derating follows a slope of −7.5 mW/°C above 25°C ambient. Proper heatsinking or airflow is required to maintain T_j within limits during sustained 500 mA operation, especially in enclosed industrial enclosures.
