Overview

2SB764F from 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 = 60–120 at I_C = −50 mA, and V_CE(sat) = −0.5 V (I_C/I_B = 10). It operates reliably in ambient temperatures from −55°C to +150°C.

For engineers reviewing the 2SB764F datasheet, pinout, applications, or equivalent options, key selection criteria include its PNP polarity, −50 V collector-emitter breakdown rating, −500 mA continuous current capability, TO-92MP package footprint, and suitability for discrete switching in low-to-medium power control circuits.

Technical Context

This transistor uses epitaxial planar construction to achieve stable DC current gain (h_FE = 60–120) across −50 mA collector current and −2 V V_CE, with guaranteed saturation voltage of −0.5 V under forced β = 10 drive conditions. Its f_T = 150 MHz at I_C = −50 mA, V_CE = −10 V enables use in moderate-speed switching.

The device meets standard industrial reliability requirements with junction temperature rating up to +150°C and storage range from −55°C to +150°C. Absolute maximum ratings strictly define safe operating area: V_CBO = −60 V, V_CEO = −50 V, V_EBO = −5 V, and I_C = −500 mA DC.

Key Specifications

Pinout & Package

2SB764F is housed in a TO-92MP (SANYO MP) plastic package with 3 leads, standardized for through-hole mounting and manual rework. Pin 1 is Emitter, Pin 2 is Collector, Pin 3 is Base - confirmed by SANYO package drawing 2006B and electrical test configuration.

Compared with 2SA1015 and MJD2955, the 2SB764F occupies a distinct mid-range niche: it delivers −500 mA capability in a compact TO-92MP package with tightly controlled h_FE and low saturation voltage-ideal for space-constrained industrial controls where neither low-current signal transistors nor high-power power devices fit.

Availability

2SB764F is available at Aetrix Electronics and suitable for industrial relay drivers, DC voltage regulators, and lamp load switches requiring stable component supply, long-term BOM continuity, and traceable sourcing.

Supply support for 2SB764F includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

SANYO Electric Co., Ltd. was a Japanese semiconductor manufacturer known for high-reliability discrete devices and analog ICs before its acquisition by Panasonic in 2012.

The 2SB764F belongs to SANYO's general-purpose PNP transistor family engineered for robustness in industrial electrical equipment, emphasizing consistent gain, low saturation voltage, and thermal stability under continuous duty.

FAQ

What is the maximum continuous collector current rating for the 2SB764F?

The 2SB764F has a maximum continuous collector current (I_C) rating of −500 mA at T_a = 25°C. This rating decreases with rising ambient temperature per the derating curve in the datasheet, reaching approximately −300 mA at 80°C ambient. The 2SB764F must not be operated beyond this limit to avoid thermal runaway or permanent degradation.

Does the 2SB764F have a documented h_FE range, and how is it binned?

Yes, the 2SB764F is binned by DC current gain: h_FE = 60–120 at I_C = −50 mA and V_CE = −2 V. This range is explicitly defined in the "Classification" section of the SANYO specification sheet No. 575–2/4. The 2SB764F does not carry suffix letters indicating tighter h_FE bins - all units meet this published range.

What package type is used for the 2SB764F, and are lead dimensions standardized?

The 2SB764F uses the TO-92MP (SANYO MP) package, with mechanical dimensions of 14.0 × 4.7 × 3.0 mm and lead pitch of 1.27 mm. Pin 1 = Emitter, Pin 2 = Collector, Pin 3 = Base - confirmed in SANYO's package drawing 2006B. Lead diameter and coplanarity comply with JEDEC TO-92 standards for automated insertion and wave soldering.

Can the 2SB764F be used in linear regulator applications, and what is its safe operating area limitation?

Yes, the 2SB764F is suitable as a series pass transistor in low-power linear regulators due to its −50 V V_CEO, −0.5 V V_CE(sat), and 0.9 W power dissipation. Its safe operating area (SOA) is limited to ≤1 A for 10 ms pulses and ≤500 mA DC; operation near V_CE > −20 V and I_C > −200 mA requires careful thermal design to stay within the SOA boundary shown in ITR08355.

Is the 2SB764F RoHS-compliant, and what is its lead finish?

The 2SB764F was manufactured prior to RoHS enforcement (catalog dated September 2003) and carries tin-lead (SnPb) solderable leads. It is not RoHS-compliant per EU Directive 2011/65/EU. For RoHS-compliant alternatives, consult SANYO/Panasonic's post-2006 PNP transistor portfolio or cross-reference with modern equivalents such as the NSS12201LT1G.
