Toshiba Semiconductor and Storage 2SA1162S-GR,LF(D

Overview

2SA1162S-GR,LF from Toshiba Electronic Devices & Storage Corporation is a silicon PNP epitaxial bipolar transistor designed for low-frequency and audio-frequency amplifier stages. It delivers VCEO = −50 V, IC(max) = −150 mA, hFE = 200–400 (GR grade), NF = 1 dB (typ.), and operates in S-Mini package with pinout Base–Emitter–Collector. It serves as a high-linearity, low-noise active device in preamplifier and driver circuits.

For engineers reviewing the 2SA1162S-GR,LF datasheet, 2SA1162S-GR,LF pinout, 2SA1162S-GR,LF application, or 2SA1162S-GR,LF equivalent, key selection criteria include guaranteed AEC-Q101 qualification for automotive use, hFE linearity ratio ≥0.95 at low-to-mid current, noise figure ≤10 dB max, and complementary pairing with 2SC2712 in push-pull designs.

Technical Context

This PNP transistor employs epitaxial base construction to achieve stable hFE across collector current (IC = −0.1 mA to −2 mA), enabling consistent gain in linear amplification. Its −50 V VCEO rating supports operation in higher-voltage analog rails, while the 200 mW PC rating (on FR4 board) defines thermal limits under continuous DC bias.

The device exhibits low noise performance (NF = 1 dB typ. at f = 1 kHz, RG = 10 kΩ) and transition frequency fT = 80 MHz (typ.), confirming suitability for audio-band signal conditioning and moderate-speed switching where gain stability matters more than RF response.

FAQ

What does the "GR" suffix indicate in 2SA1162S-GR,LF?

The "GR" suffix denotes the hFE gain bin classification: 200–400 at VCE = −6 V and IC = −2 mA. This high-gain grade ensures tighter DC bias control and improved signal-to-noise ratio in low-current amplifier stages. The 2SA1162S-GR,LF maintains this specification across its qualified operating temperature range and is validated per AEC-Q101 for automotive use.

Is 2SA1162S-GR,LF pin-compatible with other S-Mini PNP transistors?

Yes-2SA1162S-GR,LF uses the standard S-Mini (TO-236AB) package with pin 1 = Base, pin 2 = Emitter, pin 3 = Collector. It shares mechanical and solder-pad compatibility with other S-Mini PNP devices like 2SA1037AK-RL, though electrical parameters (hFE, NF, linearity) differ. Always verify bias network compatibility before substitution.

Does 2SA1162S-GR,LF require derating at elevated ambient temperatures?

Yes-its 200 mW power dissipation is rated at Ta = 25 °C on a 25.4 mm × 25.4 mm × 1.6 mm FR4 board. Derating is required above 25 °C: approximately −1.6 mW/°C above 25 °C until Tj reaches 150 °C. Full derating curves are provided in Figure 8.7 and 8.8 of the official Toshiba datasheet for 2SA1162S-GR,LF.

How is the AEC-Q101 qualification applied to 2SA1162S-GR,LF?

The 2SA1162S-GR,LF is explicitly listed in Toshiba's orderable part number table as AEC-Q101 qualified (Note 1). This qualification covers stress tests including HTGB, HTRB, TC, AC/DC life test, and ESD per JS-001, confirming suitability for automotive electronic modules. The "LF" suffix indicates lead-free plating, compliant with RoHS.

Can 2SA1162S-GR,LF be used as a direct replacement for 2SA1162-O,LF or 2SA1162-Y,LF?

No-while all share the same package and absolute ratings, the hFE bins differ: O = 70–140, Y = 120–240, GR = 200–400. Substituting 2SA1162S-GR,LF for lower-bin variants may cause overbiasing or instability in existing circuits calibrated for lower gain. Circuit revalidation is required when changing hFE grades, even within the same 2SA1162 family.
