Product details
Overview
2SA1162-Y,LF from Toshiba Electronic Devices & Storage Corporation is a silicon PNP epitaxial bipolar transistor designed for low-frequency and audio-frequency amplifier applications. It delivers VCEO = -50 V, IC(max) = -150 mA, hFE = 120–240 (Y-class), NF = 1 dB (typ.), and fT = 7 MHz, operating in S-Mini package with pinout Base–Emitter–Collector.
For engineers reviewing the 2SA1162-Y,LF datasheet, 2SA1162-Y,LF pinout, 2SA1162-Y,LF application, or 2SA1162-Y,LF equivalent, key selection considerations include AEC-Q101 qualification status, hFE linearity at low collector currents, noise performance in preamplifier stages, and complementary pairing with 2SC2712 for push-pull audio output stages.
Technical Context
This PNP transistor operates in linear amplification mode with guaranteed hFE linearity ([email protected] / hFE@-2mA = 0.95 typ.) and low-noise characteristics optimized for small-signal audio gain. Its -50 V VCEO and -150 mA IC rating support operation in Class-A and Class-AB low-power amplifier topologies.
The device is AEC-Q101 qualified for automotive use (per orderable part marking), features a 200 mW power dissipation on FR4 board, and exhibits Cob = 4 pF (typ.) and fT = 7 MHz - enabling stable gain up to mid-audio frequencies without oscillation risk in properly decoupled circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -50 V - supports rail-to-rail swing in single-supply audio preamp stages up to ±24 V supply configurations |
| IC(max) | -150 mA - enables driver-stage capability for small loudspeakers or line-level buffer loads | hFE (Y-class) | 120–240 - ensures predictable DC bias stability across production lots in discrete amplifier designs |
| NF | 1 dB (typ.), ≤10 dB (max) - meets low-noise requirements for microphone preamplifiers and phono input stages |
| fT | 7 MHz - provides usable gain-bandwidth product for audio bandwidth (20 Hz–20 kHz) with margin for feedback stability |
| Cob | 4 pF (typ.) - minimizes Miller effect in common-emitter configurations at audio frequencies |
Pinout & Package
S-Mini package: ultra-compact surface-mount plastic package (12 mg typical weight), 3-pin, JEDEC TO-236AB-compatible footprint, pin 1 = Base, pin 2 = Emitter, pin 3 = Collector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires series base resistor for bias stability in fixed-bias or voltage-divider configurations |
| 2 | Emitter | Common reference terminal in common-base and common-collector topologies; connected to ground or negative rail in most amplifier layouts |
| 3 | Collector | Output current sink node; routed to load resistor or transformer primary in single-ended amplifiers |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability per stress test protocol - suitable for infotainment preamp modules requiring extended temperature and lifetime validation |
| hFE linearity | hFE(-0.1 mA)/hFE(-2 mA) = 0.95 (typ.) - reduces harmonic distortion in low-current signal paths such as tone control networks and active filters |
| Complementary pairing | Designed as direct PNP counterpart to 2SC2712 (NPN) - enables matched push-pull output stages without thermal tracking mismatch |
| Low-noise operation | NF = 1 dB (typ.) at 1 kHz with RG = 10 kΩ - achieves SNR > 90 dB in high-gain microphone front-ends without external shielding |
Applications
| Audio Preamp Stage | Instrument Input Buffer |
|---|---|
Use Scenario: Low-noise amplification of dynamic microphone or piezoelectric pickup signals before ADC or analog processing. IC Role / Device Role / Timing Role: Small-signal PNP amplifier in common-emitter configuration with emitter degeneration for linearity.

Use Value: hFE = 120–240 (Y-class) ensures consistent gain across production units; low Cob avoids phase shift in treble band feedback loops. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP small-signal amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SA1015-Y,LF | VCEO = -50 V, hFE = 120–240, but fT = 80 MHz and Cob = 12 pF - higher bandwidth, higher capacitance | Better suited for RF coupling or wideband applications; less optimal for low-noise audio due to higher NF (2 dB typ.) | Select when bandwidth >10 MHz required; avoid where noise <1.5 dB is critical |
| MPSA92 | VCEO = -300 V, hFE = 25–200, NF = 10 dB (max), no AEC-Q101 qualification | Higher voltage tolerance for industrial HV bias rails; lacks automotive qualification and low-noise optimization | Choose for non-automotive high-voltage switching or amplifier rails >60 V; not recommended for automotive audio |
Compared with 2SA1162-Y,LF, 2SA1015-Y,LF trades lower noise for wider bandwidth, while MPSA92 offers higher breakdown voltage at the cost of noise performance and automotive compliance - making 2SA1162-Y,LF the optimal choice for AEC-Q101-compliant, low-distortion audio preamplification.

FAQ
What is the hFE classification and range for 2SA1162-Y,LF?
The "Y" suffix in 2SA1162-Y,LF denotes hFE classification Y, specifying a guaranteed DC current gain range of 120 to 240 at VCE = -6 V and IC = -2 mA. This binning ensures predictable bias point stability in production amplifier designs and supports interchangeability within Y-class units without circuit re-tuning.
Is 2SA1162-Y,LF qualified for automotive applications?
Yes, 2SA1162-Y,LF is AEC-Q101 qualified, as confirmed in Toshiba's official orderable part number table. This qualification applies specifically to the -Y,LF variant and covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life - validating its use in automotive infotainment and body control module signal paths.
What is the pinout configuration of 2SA1162-Y,LF in the S-Mini package?
The 2SA1162-Y,LF uses the S-Mini (TO-236AB) package with standardized pinout: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. This matches JEDEC outline and is mechanically and electrically compatible with other S-Mini transistors used in space-constrained audio PCB layouts.
How does the noise figure of 2SA1162-Y,LF compare to similar PNP transistors?
2SA1162-Y,LF achieves a typical noise figure of 1 dB at 1 kHz with RG = 10 kΩ, significantly lower than standard PNP transistors like MPSA92 (10 dB max). This makes 2SA1162-Y,LF especially suitable for microphone preamps and phono stages where preserving signal-to-noise ratio is critical.
What complementary NPN transistor pairs with 2SA1162-Y,LF?
Toshiba explicitly identifies 2SC2712 as the complementary NPN counterpart to 2SA1162-Y,LF. Both share matching hFE ranges, thermal characteristics, and S-Mini packaging - enabling thermally balanced push-pull output stages and differential amplifier designs without manual matching.
