Product details

Overview

HS2GAH from Taiwan Semiconductor is a 1.5A, 600V glass-passivated surface-mount fast recovery rectifier in DO-214AC (SMA) package, optimized for automotive DC-DC converters and snubber circuits with 50ns reverse recovery time and 1.3V forward voltage at 1.5A.

For engineers reviewing the HS2GAH datasheet, HS2GAH pinout, HS2GAH application, or HS2GAH equivalent, key selection criteria include its 600V V_RRM, 50A I_FSM, AEC-Q101 qualification, J_unction temperature rating up to 150°C, and DO-214AC mechanical compatibility with automated SMT assembly.

Technical Context

The HS2GAH implements a single-die silicon PN junction structure with glass passivation for enhanced reliability under thermal cycling and humidity stress. Its 50ns trr and 1.3V V_F at 1.5A support high-frequency switching in automotive power supplies and freewheeling paths where low conduction loss and fast turn-off are critical.

Designed for AEC-Q101 compliance, the device operates across –55°C to +150°C junction temperature range and features matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements - essential for under-hood automotive environments.

FAQ

What is the maximum junction temperature rating for HS2GAH?

The HS2GAH has a maximum junction temperature (T_J) rating of +150°C, verified per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments where ambient temperatures exceed 125°C. The device must be mounted on PCB copper areas sufficient to maintain T_J ≤ 150°C under worst-case I_F = 1.5A and ambient conditions - refer to the R_θJA = 80°C/W thermal metric in the HS2GAH datasheet for layout guidance.

Is HS2GAH AEC-Q101 qualified and what tests does that include?

Yes, HS2GAH is AEC-Q101 qualified. Certification includes temperature cycling (–55°C to +150°C), high-temperature reverse bias (HTRB), unbiased highly accelerated stress test (UHAST), and mechanical shock/vibration per AEC-Q101 Rev D. These tests validate performance stability across automotive life cycles. The HS2GAH qualification applies specifically to the DO-214AC packaged variant and is documented in Taiwan Semiconductor's official AEC-Q101 certificate for the HS2x family.

What is the forward voltage drop of HS2GAH at rated current?

The HS2GAH exhibits a maximum forward voltage (V_F) of 1.3 V at I_F = 1.5 A and T_J = 25°C, measured under pulsed conditions (PW = 0.3 ms). At elevated junction temperatures (e.g., 125°C), V_F decreases slightly due to negative temperature coefficient of silicon diodes. This 1.3 V value directly determines conduction loss - 1.95 W at full rated current - and informs thermal design of the HS2GAH in final application.

Does HS2GAH have a specified reverse recovery time, and how is it measured?

Yes, HS2GAH has a maximum reverse recovery time (t_rr) of 50 ns, tested under I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per JEDEC standard. This parameter is critical for minimizing switching loss and EMI in high-frequency DC-DC converters. The 50 ns t_rr is confirmed across the full operating temperature range and distinguishes HS2GAH from slower general-purpose rectifiers like 1N4007 (2 µs) or even some 600V Schottky alternatives with higher leakage.

What package type and marking does HS2GAH use?

HS2GAH uses the DO-214AC (SMA) surface-mount package with cathode polarity indicated by a visible band. The device marking code is "HS2GA" printed on the body, followed by date and factory codes. The package features matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and meets JESD201 Class 2 whisker resistance - all explicitly specified for the HS2GAH variant in Taiwan Semiconductor's A2102 datasheet revision.
