Product details
Overview
HS1GLH from Taiwan Semiconductor is a 1 A, 400 V repetitive peak reverse voltage (VRRM), surface-mount glass-passivated silicon rectifier diode in Sub SMA package, with 1.30 V forward voltage at 1 A and 50 ns reverse recovery time, used for freewheeling and snubber functions in automotive DC-DC converters.
For engineers reviewing the HS1GLH datasheet, HS1GLH pinout, HS1GLH application, or HS1GLH equivalent, key selection criteria include its 400 V VRRM rating, 1.30 V VF at 1 A, 50 ns trr, Sub SMA package compatibility with automated placement, and AEC-Q101 qualification for automotive reliability.
Technical Context
This device is a single-die, unidirectional, high-efficiency fast recovery rectifier optimized for switching power supplies. Its 50 ns reverse recovery time and 20 pF junction capacitance at 1 MHz / 4.0 V reverse bias support high-frequency operation in flyback and buck-derived topologies.
The Sub SMA package provides low thermal resistance (RθJA = 100 °C/W) and moisture sensitivity level 1 handling, while the glass-passivated junction ensures stable performance across -55 °C to +150 °C junction temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L04S | 400 V VRRM, 1.05 V VF @ 1 A, 30 ns trr, SMA package | Lower VF and faster trr improve efficiency in high-frequency (>300 kHz) designs | Preferred where lower conduction and switching loss are critical; requires verification of SMA vs. Sub SMA pad compatibility |
| ON Semi MUR140 | 400 V VRRM, 1.25 V VF @ 1 A, 50 ns trr, SMA package | Near-identical electrical specs but not AEC-Q101 qualified | Suitable for industrial/non-automotive use; may reduce cost where automotive qualification is unnecessary |
Compared with STTH1L04S and MUR140, the HS1GLH offers AEC-Q101 qualification and Sub SMA footprint-critical for space-constrained automotive modules-while maintaining matched VRRM and trr, though with slightly higher VF than STTH1L04S.

FAQ
What is the peak repetitive reverse voltage rating for HS1GLH?
The HS1GLH has a peak repetitive reverse voltage (VRRM) rating of 400 V, verified per Taiwan Semiconductor's official datasheet revision A2103. This rating defines the maximum reverse voltage the diode can block repeatedly without avalanche breakdown under normal operating conditions. The HS1GLH is part of the HS1ALH–HS1MLH series where 'G' denotes the 400 V variant, confirmed by the marking code 'HGL' on the device body.
What is the forward voltage drop of HS1GLH at rated current?
The HS1GLH exhibits a maximum forward voltage (VF) of 1.30 V at 1 A forward current and 25°C junction temperature, as specified in the Electrical Specifications table of the official datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction losses in power stage design. The HS1GLH's VF is higher than lower-voltage variants like HS1ALH (0.95 V) due to its wider bandgap silicon structure optimized for 400 V blocking.
Is HS1GLH qualified for automotive applications?
Yes, the HS1GLH is explicitly AEC-Q101 qualified, as stated in the FEATURES section of the official Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming suitability for under-hood and cabin automotive systems. The HS1GLH's -55 °C to +150 °C operating temperature range and moisture sensitivity level 1 further support automotive manufacturing and deployment requirements.
What package type does HS1GLH use, and how does it differ from standard SMA?
The HS1GLH uses the Sub SMA package-a reduced-height variant of the standard SMA outline-with identical lead pitch and pad layout but lower profile for space-constrained PCBs. Per the PACKAGE OUTLINE DIMENSIONS drawing in the datasheet, Sub SMA features a maximum height of 1.6 mm versus 2.3 mm for standard SMA. The HS1GLH's Sub SMA package retains matte tin-plated leads compliant with J-STD-002 and supports automated placement without modification to existing SMA feeders.
What is the junction capacitance of HS1GLH and at what test conditions?
The junction capacitance (CJ) of the HS1GLH is 20 pF, measured at 1 MHz frequency and 4.0 V reverse bias (VR), as documented in the ELECTRICAL SPECIFICATIONS table. This value is specific to the HS1GLH variant and differs from higher-voltage members (e.g., HS1JLH–HS1MLH at 15 pF). Low CJ helps minimize capacitive coupling and switching noise in high-frequency snubber and freewheeling applications where the HS1GLH is commonly deployed.
