Product details
Overview
2SA1832-Y,LF from Toshiba Electronic Devices & Storage Corporation is a silicon PNP epitaxial bipolar transistor designed for low-frequency amplifier stages in automotive and industrial signal conditioning circuits, with VCEO = −50 V, IC(max) = −150 mA, hFE = 120–240 (Y-rank), fT = 7 MHz (typ.), and AEC-Q101 qualified for automotive use.
For engineers reviewing the 2SA1832-Y,LF datasheet, 2SA1832-Y,LF pinout, 2SA1832-Y,LF application, or 2SA1832-Y,LF equivalent, key selection criteria include its complementary pairing with 2SC4738, SOT-416 (SSM) package footprint, −50 V breakdown rating, hFE linearity (0.95 typ.), and suitability for linear amplification where low distortion and stable DC bias are required.
Technical Context
This PNP transistor operates in active and saturation regions for analog gain and switching functions, supporting linear amplification with verified hFE linearity across IC = −0.1 mA to −2 mA. Its −50 V VCEO and −5 V VEBO ratings enable robust operation in negative-rail bias configurations.
The device uses an epitaxial base structure to achieve high fT (7 MHz typ.) and low Cob (4 pF typ.) while maintaining tight hFE distribution (Y-rank: 120–240). It is rated for junction temperatures up to 125 °C and mounted on standard FR4 PCBs per JEDEC SOT-416 thermal guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Supports amplifier stages operating with up to −45 V collector supply before breakdown. |
| IC(max) | −150 mA: Enables drive capability for medium-current load interfaces without external buffering. |
| hFE (Y-rank) | 120–240: Ensures predictable DC bias stability and gain consistency in production designs. |
| fT | 7 MHz (typ.): Validates usable bandwidth for audio and sub-MHz signal amplification. |
| Cob | 4 pF (typ. at VCB = −10 V): Limits Miller capacitance impact on high-frequency gain roll-off. |
| VCE(sat) | −0.3 V (max. at IC = −100 mA, IB = −10 mA): Reduces conduction loss in saturated-switch applications. |
| Package | SOT-416 (SSM): 3-pin surface-mount footprint with 0.95 mm pitch, compatible with automated assembly. |
Pinout & Package
2SA1832-Y,LF is housed in the JEDEC-standard SOT-416 (SSM) package - a 3-pin ultra-small molded plastic case with 2.4 mg typical weight and 0.95 mm lead pitch. Pin 1 is Base, Pin 2 is Emitter, Pin 3 is Collector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Current-controlled input terminal | Accepts forward-biased base current to regulate collector-emitter conduction; requires series resistor for stable biasing. |
| 2 (Emitter) | Common emitter node | Connected to negative rail or ground reference; provides return path for both base and collector currents. |
| 3 (Collector) | Output current terminal | Sinks current from load to emitter; supports up to −150 mA DC with < −0.3 V saturation voltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
| High hFE linearity | hFE(IC = −0.1 mA)/hFE(IC = −2 mA) = 0.95 (typ.): Minimizes harmonic distortion in Class-A amplifier bias points. |
| Complementary pairing | Designed as direct PNP complement to NPN 2SC4738: enables matched push-pull and differential pair implementations. |
| Low Cob | 4 pF (typ.): Reduces feedback capacitance in common-emitter gain stages, preserving phase margin. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP bipolar transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SA1774-Y,LF | Higher VCEO (−60 V), lower hFE (100–200), same SOT-416 package | Better suited for higher-voltage industrial supplies; reduced gain uniformity vs. 2SA1832-Y,LF | Select when > −50 V breakdown margin is required and gain tolerance can be relaxed. |
| MMBT2907ALT1G | Lower VCEO (−60 V), wider hFE range (100–300), SOT-23 package (larger footprint) | Compatible in non-automotive general-purpose amplifiers; not AEC-Q101 qualified | Choose for cost-sensitive consumer designs where automotive qualification is unnecessary. |
Compared with 2SA1832-Y,LF, 2SA1774-Y,LF offers higher voltage headroom but narrower hFE consistency, while MMBT2907ALT1G provides broader hFE spread in a larger SOT-23 package without automotive qualification-making 2SA1832-Y,LF optimal for AEC-Q101-compliant, space-constrained, linear-amplifier applications demanding tight gain control.

FAQ
What is the hFE classification and test condition for 2SA1832-Y,LF?
The 2SA1832-Y,LF has Y-rank hFE, specified as 120–240 at VCE = −6 V and IC = −2 mA. This classification is laser-marked on the device body and verified per production test. The hFE linearity ratio hFE(IC = −0.1 mA)/hFE(IC = −2 mA) is 0.95 (typ.), confirming minimal gain variation across bias points-critical for low-distortion amplifier design using the 2SA1832-Y,LF.
Is 2SA1832-Y,LF qualified for automotive applications?
Yes, 2SA1832-Y,LF is explicitly AEC-Q101 qualified, as confirmed in Toshiba's orderable part number table and datasheet revision 3.0.A. It undergoes stress testing for temperature cycling, high-temperature reverse bias, and electrostatic discharge per automotive reliability requirements-making it suitable for under-hood and cabin electronics where the 2SA1832-Y,LF is deployed in production vehicles.
What is the package type and pin configuration of 2SA1832-Y,LF?
The 2SA1832-Y,LF uses the SOT-416 (SSM) package: a 3-pin ultra-small surface-mount outline with JEDEC registration. Pin 1 is Base, Pin 2 is Emitter, Pin 3 is Collector. This matches the mechanical and thermal specifications defined in Toshiba's package drawing, ensuring compatibility with standard SMT reflow profiles and pick-and-place equipment used for the 2SA1832-Y,LF.
How does 2SA1832-Y,LF compare to its complementary NPN counterpart?
The 2SA1832-Y,LF is designed as the PNP complement to the NPN 2SC4738, sharing matching VCEO (−50 V / +50 V), IC(max) (−150 mA / +150 mA), and SOT-416 packaging. Their hFE ranges are aligned (Y-rank 120–240 vs. 2SC4738's Y-rank 120–240), enabling balanced performance in push-pull, differential, and complementary-symmetry amplifier topologies using either the 2SA1832-Y,LF or 2SC4738.
What are the absolute maximum ratings for 2SA1832-Y,LF at Ta = 25 °C?
At ambient temperature 25 °C, the 2SA1832-Y,LF has VCBO = −50 V, VCEO = −50 V, VEBO = −5 V, IC = −150 mA, IB = −30 mA, PC = 120 mW, Tj = 125 °C, and Tstg = −55 to 150 °C. These ratings assume mounting on a 25.4 mm × 25.4 mm × 1.6 mm FR4 board with specified copper pad area-derating is required above 25 °C ambient per the 2SA1832-Y,LF thermal curve data.
