Product details
Overview
2SA1832-GR,LXHF from Toshiba Electronic Devices & Storage Corporation is a silicon PNP epitaxial bipolar transistor qualified to AEC-Q101 for automotive use, featuring VCEO = −50 V, IC(max) = −150 mA, hFE = 200–400 (GR rank), and packaged in SOT-416 (SSM). It serves as a low-frequency amplifier or switching device in automotive sensor signal conditioning and body control modules.
For engineers reviewing the 2SA1832-GR,LXHF datasheet, 2SA1832-GR,LXHF pinout, 2SA1832-GR,LXHF application, or 2SA1832-GR,LXHF equivalent, key selection criteria include its AEC-Q101 qualification, GR-grade hFE linearity, −50 V breakdown rating, and SSM package thermal performance on FR4 boards.
Technical Context
This PNP transistor operates with emitter-grounded configuration and supports DC amplification and switching in low-frequency analog circuits. Its hFE classification GR (200–400) ensures stable gain across IC = −0.1 mA to −2 mA, with typical hFE linearity ratio of 0.95.
The device exhibits VCE(sat) ≤ −0.3 V at IC = −100 mA/IB = −10 mA and fT ≥ 7 MHz at VCE = −10 V/IC = −1 mA, confirming suitability for audio preamplifier stages and discrete logic-level translation where low saturation voltage and moderate bandwidth are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown under open-base condition; enables use in 24 V automotive supply rails with margin. |
| IC(max) | −150 mA: Continuous DC collector current limit; supports driver-stage loads such as small relays or LED arrays. |
| hFE (GR rank) | 200–400 at VCE = −6 V, IC = −2 mA: High and tightly binned DC current gain for consistent biasing in linear amplifier designs. |
| VCE(sat) | ≤ −0.3 V at IC = −100 mA, IB = −10 mA: Low saturation voltage minimizes power loss in switching applications. |
| fT | ≥ 7 MHz at VCE = −10 V, IC = −1 mA: Sufficient gain-bandwidth for audio-frequency amplification up to ~100 kHz. |
| Cob | Typ. 4 pF at VCB = −10 V, f = 1 MHz: Low output capacitance preserves high-frequency response in multi-stage amplifiers. |
Pinout & Package
Package: SOT-416 (SSM), surface-mount, 3-pin, 2.4 mg typical weight, JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal for forward-biased junction; requires current-limited drive to achieve specified hFE and VCE(sat). |
| 2 | Emitter | Current source terminal in PNP operation; connected to higher potential (e.g., VCC) in common-emitter configurations. |
| 3 | Collector | Output terminal; sinks current to load when base is forward-biased; rated for −50 V reverse bias relative to emitter. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature range (−40 °C to +125 °C junction) and reliability stress testing per AEC standard. |
| High hFE linearity | hFE(IC = −0.1 mA)/hFE(IC = −2 mA) = 0.95 typ., enabling stable small-signal gain across operating current range. |
| Complementary pair | Designed as PNP counterpart to 2SC4738 NPN, facilitating matched push-pull or differential amplifier implementations. |
| Small-outline package | SOT-416 (SSM) footprint saves PCB area and supports automated assembly; thermal resistance θJA ≈ 200 °C/W on 25.4 mm × 25.4 mm FR4 board. |
Applications
| Automotive Door Module Amplifier | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Amplifying low-level analog signals from door latch position sensors in 12 V/24 V automotive body control units. IC Role / Device Role / Timing Role: PNP small-signal amplifier in common-emitter configuration, providing gain and level-shifting before ADC input.

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-GR,LF | VCEO = −50 V, IC = −150 mA, hFE = 200–400, same SOT-416 package, but not AEC-Q101 qualified. | General-purpose industrial use only; unsuitable for automotive ECUs requiring AEC certification. | Select 2SA1832-GR,LXHF when AEC-Q101 compliance is mandatory; choose 2SA1774-GR,LF for cost-sensitive non-automotive designs. |
| MMBT2907ALT1G | VCEO = −60 V, IC = −600 mA, hFE = 100–300, SOT-23 package, AEC-Q101 qualified. | Higher current capability and wider voltage margin, but larger die and different pinout (1=Emitter, 2=Base, 3=Collector). | Use MMBT2907ALT1G where >150 mA load current or −60 V standoff is required; verify PCB layout compatibility due to SOT-23 vs. SOT-416 footprint mismatch. |
Compared with 2SA1774-GR,LF and MMBT2907ALT1G, the 2SA1832-GR,LXHF uniquely combines AEC-Q101 qualification, GR-grade hFE linearity, and SOT-416 footprint-making it optimal for space-constrained automotive signal amplification where gain consistency and reliability are critical.

FAQ
What does the "GR" suffix indicate in 2SA1832-GR,LXHF?
The "GR" suffix denotes the hFE gain bin: 200–400 at VCE = −6 V and IC = −2 mA. This tight binning ensures predictable DC current gain for precision biasing in amplifier and switching circuits. The 2SA1832-GR,LXHF maintains this specification across its qualified operating temperature range and is verified per Toshiba's production test flow.
Is 2SA1832-GR,LXHF suitable for automotive applications?
Yes, 2SA1832-GR,LXHF is explicitly qualified to AEC-Q101 for automotive use, as confirmed in Toshiba's orderable part number table. It meets stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life-making it appropriate for under-hood and cabin modules where reliability is critical.
What is the package type and pin configuration of 2SA1832-GR,LXHF?
The 2SA1832-GR,LXHF uses the SOT-416 (SSM) package: Pin 1 is Base, Pin 2 is Emitter, Pin 3 is Collector. This JEDEC-standard 3-pin surface-mount outline measures 1.6 mm × 0.8 mm × 0.55 mm and weighs 2.4 mg, supporting high-density PCB layouts and reflow soldering.
How does the hFE linearity of 2SA1832-GR,LXHF benefit circuit design?
The 2SA1832-GR,LXHF achieves typical hFE linearity of 0.95 - defined as hFE(IC = −0.1 mA)/hFE(IC = −2 mA). This minimizes gain variation across operating current, improving accuracy in analog amplifiers and reducing distortion in Class-A stages without requiring complex feedback compensation.
What is the maximum power dissipation for 2SA1832-GR,LXHF on a standard PCB?
At Ta = 25 °C on a 25.4 mm × 25.4 mm × 1.6 mm FR4 board with 0.36 mm² copper pads, the 2SA1832-GR,LXHF has PC = 120 mW. Derating applies above 25 °C: approximately −1.2 mW/°C, reaching zero dissipation at ~125 °C ambient - consistent with its 125 °C max junction temperature rating.
