Product details
Overview
2SB892S-AE from SANYO Semiconductor is a PNP epitaxial planar silicon transistor designed for large-current switching applications, with VCEO = −50 V, IC = −2 A, PC = 1 W, hFE = 100–560 (at IC = −100 mA), and VCE(sat) = −0.15 to −0.4 V (at IC = −1 A, IB = −50 mA). It is used in automotive wiring, relay drivers, and lamp drivers where low saturation voltage and wide safe operating area (ASO) are critical.
For engineers reviewing the 2SB892S-AE datasheet, pinout, applications, or equivalent options, key selection considerations include its PNP polarity, TO-126 package mapping, guaranteed hFE grading (Rank S: 140–280), −0.9 to −1.2 V VBE(sat), and fT = 150 MHz - all confirmed per SANYO No.930 data sheet.
Technical Context
The 2SB892S-AE employs SANYO's proprietary FBET and MBIT processing to achieve low VCE(sat) and high current gain consistency across temperature. Its −50 V VCEO rating and 150 °C Tj support robust operation in automotive and industrial power-switching nodes.
It operates as a medium-power PNP switch with DC current gain specified at two test points: hFE1 = 100–560 @ VCE = −2 V, IC = −100 mA and hFE2 = 40 min @ VCE = −2 V, IC = −1.5 A - enabling reliable drive under both small-signal bias and high-load saturation conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter blocking voltage before breakdown in common-emitter configuration. |
| IC | −2 A continuous: Rated collector current for sustained switching without thermal derating at Ta = 25 °C. |
| VCE(sat) | −0.15 to −0.4 V @ IC = −1 A, IB = −50 mA: Low saturation voltage enables minimal conduction loss in high-current PNP switch designs. |
| hFE | 140–280 (Rank S): Guaranteed DC current gain range at IC = −100 mA, ensuring predictable base drive requirements. |
| fT | 150 MHz: Gain-bandwidth product confirming usable frequency response up to audio and low-RF switching speeds. |
| PC | 1 W: Maximum power dissipation at case temperature ≤ 25 °C; requires heatsinking above ambient derating thresholds. |
| Cob | 12 pF @ VCB = −10 V, f = 1 MHz: Output capacitance affecting switching speed and EMI in hard-switched topologies. |
Pinout & Package
2SB892S-AE is housed in a TO-126 plastic package (SANYO MP designation), with lead-free plating and standard through-hole mounting. Pin 1 = Emitter, Pin 2 = Collector, Pin 3 = Base - verified per SANYO package drawing 7520-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal for PNP device | Connected to higher potential rail; carries full load current in high-side switch configurations. |
| 2 (Collector) | Current sink terminal | Typically tied to load return path or ground-referenced load; voltage swing limited by VCEO rating. |
| 3 (Base) | Control input for bipolar junction | Requires negative current injection relative to emitter to turn on; base resistor sizing must ensure IB ≥ IC/hFE(min). |
Key Features
| Feature | Design Value |
|---|---|
| FBET/MBIT process technology | Enables tight hFE distribution and stable VCE(sat) across production lots and temperature. |
| Wide Safe Operating Area (ASO) | Supports pulsed ICP = −4 A without secondary breakdown, critical for inductive load switching. |
| Low VBE(sat) | −0.9 to −1.2 V @ IC = −1 A ensures minimal base drive power loss in high-current applications. |
| High junction temperature rating | Tj = 150 °C allows operation in under-hood automotive environments with appropriate thermal design. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SB1260-Z | VCEO = −60 V, IC = −3 A, PC = 1.5 W, TO-126 package | Higher voltage/current ratings; wider ASO margin for 24 V industrial systems | Select when higher blocking voltage or thermal headroom is required beyond 2SB892S-AE specs. |
| MJD2955T4G | VCEO = −60 V, IC = −10 A, PC = 1.5 W, DPAK surface-mount package | SMT-compatible; higher current but different footprint and thermal interface | Choose for automated assembly and space-constrained PCBs where TO-126 through-hole is impractical. |
Compared with 2SB892S-AE, 2SB1260-Z offers extended voltage and current margins in the same TO-126 form factor, while MJD2955T4G provides significantly higher current capacity in a surface-mount package - making it suitable for next-generation compact power stages where reworkability and layout density are prioritized over legacy through-hole compatibility.

FAQ
What is the hFE grade of 2SB892S-AE?
The 2SB892S-AE is specifically graded as Rank S, with DC current gain hFE = 140–280 measured at VCE = −2 V and IC = −100 mA. This tighter binning ensures predictable base drive requirements in production designs, distinguishing it from broader-range variants like Rank R (100–200) or Rank U (280–560) within the same 2SB892 family.
Is 2SB892S-AE RoHS compliant?
Yes, 2SB892S-AE is RoHS compliant and features lead-free plating per SANYO's EN930D specification. The TO-126 package uses Pb-free terminations and conforms to JEDEC J-STD-020 moisture sensitivity level (MSL) 1 - suitable for standard reflow and wave soldering processes without special handling.
Can 2SB892S-AE replace 2SB892 in existing designs?
Yes, 2SB892S-AE is a direct replacement for the base 2SB892, sharing identical electrical specifications, TO-126 package, pinout, and thermal characteristics. The "S-AE" suffix denotes SANYO's standard-grade, RoHS-compliant version with Rank S hFE binning - no layout or schematic changes are needed when upgrading from legacy 2SB892 parts.
What is the maximum pulsed collector current for 2SB892S-AE?
The maximum pulsed collector current ICP for 2SB892S-AE is −4 A, specified at pulse width ≤ 10 ms and duty cycle ≤ 10%. This rating is validated under the Wide ASO condition and supports short-duration inrush current handling in lamp and relay driving applications without secondary breakdown.
Does 2SB892S-AE require a heatsink in 1 W continuous operation?
Yes, 2SB892S-AE dissipates up to 1 W continuously only at Ta = 25 °C with adequate heatsinking. Its thermal resistance θJA is approximately 150 °C/W (TO-126, no heatsink); therefore, a minimum heatsink or copper pour is required to maintain Tj ≤ 150 °C in real-world ambient conditions above 25 °C - especially in enclosed automotive or industrial enclosures.
