Product details
Overview
HS1JLH from Taiwan Semiconductor is a 600 V, 1 A surface-mount high-efficiency fast recovery rectifier diode in Sub SMA package, featuring 75 ns reverse recovery time, 1.70 V forward voltage at 1 A, and 5 µA reverse leakage at 25°C - used in automotive DC-DC converters and snubber circuits.
For engineers reviewing the HS1JLH datasheet, HS1JLH pinout, HS1JLH application, or HS1JLH equivalent, key selection criteria include peak reverse voltage (600 V), thermal resistance (100 °C/W), junction capacitance (15 pF), AEC-Q101 qualification, and Sub SMA mechanical compatibility with automated placement.
Technical Context
The HS1JLH is a single-die, glass-passivated silicon rectifier optimized for fast switching in high-reliability automotive and industrial power conversion. Its 75 ns trr and low 15 pF junction capacitance support efficient operation in 50–500 kHz DC-DC topologies while maintaining low conduction loss via 1.70 V VF at rated current.
Designed for junction temperatures up to +150°C and moisture sensitivity level 1 (J-STD-020), the HS1JLH integrates matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance - enabling robust reflow assembly in automotive lighting and freewheeling applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06S | 600 V VRRM, 1.05 V VF @ 1 A, 50 ns trr, SMA package | Lower VF reduces conduction loss but requires tighter layout due to faster switching edge | Preferred where thermal margin is constrained and layout supports fast-edge EMI control |
| ES1J | 600 V VRRM, 1.7 V VF @ 1 A, 75 ns trr, SMA package (not Sub SMA) | Slightly taller profile (2.7 mm vs. 2.3 mm) may impact ultra-low-height assemblies | Drop-in substitute only if board clearance ≥2.7 mm and pad layout matches standard SMA |
Compared with STTH1R06S and ES1J, the HS1JLH offers AEC-Q101 qualification and Sub SMA low-profile packaging - making it uniquely suitable for automotive modules where reliability validation and height constraints coexist.

FAQ
What is the maximum repetitive peak reverse voltage rating for HS1JLH?
The HS1JLH has a maximum repetitive peak reverse voltage (VRRM) of 600 V, verified per Taiwan Semiconductor's A2103 datasheet revision. This rating ensures reliable blocking capability in automotive 12 V/24 V systems experiencing load dump transients up to 40 V, and in industrial 48 V DC bus applications. The 600 V margin provides design headroom against voltage spikes in flyback and snubber circuits.
Is HS1JLH qualified for automotive applications?
Yes, HS1JLH is AEC-Q101 qualified per its official datasheet, confirming compliance with stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST). This qualification makes HS1JLH suitable for under-hood and cabin applications such as engine control units, body electronics, and LED lighting modules where reliability under thermal and vibration stress is critical.
What is the forward voltage drop of HS1JLH at 1 A and 25°C?
The forward voltage (VF) of HS1JLH is specified as a maximum of 1.70 V at 1 A forward current and 25°C junction temperature. This value directly determines conduction loss (1.7 W at full load) and impacts thermal design in enclosed modules. At 125°C, VF decreases slightly due to negative temperature coefficient - typical behavior for silicon PN-junction rectifiers.
Does HS1JLH have a defined reverse recovery time, and how is it measured?
Yes, HS1JLH has a maximum reverse recovery time (trr) of 75 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC standards. This parameter reflects the diode's ability to transition from conduction to blocking state, directly influencing switching losses and EMI in high-frequency DC-DC converters. The 75 ns value places HS1JLH in the fast recovery category, distinct from standard or ultrafast rectifiers.
What package type does HS1JLH use, and what are its key mechanical features?
HS1JLH uses the Sub SMA package - a low-profile variant of SMA with maximum height of 2.3 mm, UL 94V-0 flammability rating, and matte tin-plated leads compliant with J-STD-002 solderability. Its polarity is marked by a cathode band, and it weighs approximately 0.019 g. The Sub SMA footprint enables high-density placement in automotive ECUs and LED drivers where vertical space is constrained.
