概述

Description

2SA1774TLR is a PNP silicon power transistor in the 2SA (Japanese) family. The “TLR” suffix usually denotes a Tape & Reel packaging option (for automated assembly) and lead-free variants; exact packaging and ratings depend on the manufacturer.
Key points:
- Type: PNP power transistor; complementary to 2SC1774.
- Common use: audio power amplifier output stages and power-supply regulator circuits.
- Replacement/ specs: For exact Vceo, Ic, hFE, Pd, pinout, and package, refer to the manufacturer’s datasheet or distributor listing.
- Availability: It’s an older device; some vendors may list it as discontinued or require cross-refs to modern equivalents.
If you’re designing or repairing, always verify the specific datasheet for the exact variant you have (since packaging and ratings can vary by maker).

Features

2SA1774TLR features (concise):
- PNP transistor (complement of 2SC1775)
- Package: TO-92 in Tape & Reel (TLR)
- Vceo: about 60 V
- Ic: approx. 0.5 A
- Pd: roughly 0.8 W
- hFE: typically 60–250 (depends on Ic)
- Applications: general-purpose small-signal/audio driver
Note: exact numbers can vary by lot; check the data sheet for your specific lot.

Package

"TLR" on 2SA1774TLR indicates tape-and-reel shipment packaging. The exact component package (SOT-23, SOT-89, TO‑92, etc.) depends on the manufacturer's ordering code—check the specific 2SA1774 datasheet or part marking for the exact package type.

Pinout

- Pin count: 3 pins
- Function: PNP power transistor (complement to 2SC1774), used for high-current amplification or switching. Terminals are emitter, base, and collector; exact pinout depends on the specific TL R package—consult the datasheet for your part.

Manufacturer

Manufacturer: ROHM Co., Ltd. (ROHM Semiconductor).
What kind of company: ROHM is a Japanese semiconductor company (headquartered in Kyoto) that designs and manufactures discrete semiconductors (transistors, diodes, MOSFETs), analog and power ICs, optoelectronics and related modules for consumer, industrial and automotive applications.

Application

2SA1774TLR is a PNP power transistor. Typical applications include:
- Push-pull audio output stages and driver stages
- Linear regulator pass element
- Front-end/pass element in switching regulators (SMPS)
- General high-current PNP switch in power and motor-drive circuits
Useful in any circuit needing a PNP power transistor with appreciable current capability.

Equivalent

I don’t have real‑time part databases. To give accurate equivalents I need the 2SA1774’s key specs (package, PNP/NPN, Vce, Ic, Pd, hFE, fT). Please paste its datasheet or those parameters — then I can list proper substitutes (or cross-references) concisely.
