Product details
Overview
HS1JALH from Taiwan Semiconductor is a 1A, 600V glass-passivated surface-mount rectifier in Thin SMA package, featuring 1.02V forward voltage at 1.0A/25°C, 75ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability in DC/DC converters and snubber circuits.
For engineers reviewing the HS1JALH datasheet, HS1JALH pinout, HS1JALH application, or HS1JALH equivalent, key selection criteria include its 600V VRRM, 35A IFSM surge rating, 13pF junction capacitance, -55°C to +150°C operating range, and Thin SMA thermal performance (RθJA = 51°C/W).
Technical Context
The HS1JALH is a single-die, standard-recovery silicon rectifier optimized for high-efficiency switching applications requiring low forward loss and fast reverse recovery. Its 75ns trr and 13pF CJ support operation in medium-frequency DC/DC topologies up to several hundred kHz.
Designed with glass-passivated junction and matte tin-plated leads, it meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1. Polarity is marked by cathode band; mounting uses standard reflow profiles on 5mm × 5mm Cu pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking capability in 48V–400V bus systems. |
| IF | 1 A - Continuous average forward current; supports sustained conduction in compact power stages without forced cooling. |
| VF @ 1A, 25°C | 1.02 V (typ), 1.70 V (max) - Directly determines conduction loss (Pcond ≈ 1.02W @ 1A); lower than HS1KALH/HS1MALH variants. |
| trr | 75 ns - Reverse recovery time; enables efficient operation in flyback and forward converters switching up to ~500 kHz. |
| CJ | 13 pF - Junction capacitance at 1 MHz / 4V; reduces high-frequency switching noise and EMI in snubber networks. |
| RθJA | 51 °C/W - Thermal resistance from junction to ambient on standard PCB; enables 1A operation at ≤85°C ambient with minimal copper area. |
| TJ max | +150 °C - Maximum junction temperature; allows use in under-hood automotive environments with derating. |
Pinout & Package
Package: Thin SMA (Surface Mount Assembly), low-profile, RoHS-compliant, halogen-free molding compound meeting UL 94V-0. Cathode indicated by band; matte tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; requires thermal relief pad for soldering and heat dissipation. |
| Cathode | Forward current exit / reverse voltage blocking terminal | Marked by band; connects to higher-potential node; critical for polarity-sensitive snubber and freewheeling paths. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including temperature cycling, HTRB, and ESD; suitable for engine control and ADAS power supplies. |
| Glass-passivated junction | Enhances long-term reliability and moisture resistance vs. epoxy-passivated alternatives; prevents junction degradation under thermal cycling. |
| Low profile Thin SMA | Height ≤1.1 mm enables use in space-constrained modules such as LED drivers and portable DC/DC regulators. |
| Junction-to-lead thermal resistance | RθJL = 29 °C/W - Enables direct heat transfer to PCB copper; improves thermal margin over standard SMA packages. |
| Moisture Sensitivity Level 1 | No baking required prior to reflow; simplifies SMT line integration and eliminates moisture-related popcorning risk. |
Applications
| Freewheeling Diode | Snubber Network |
|---|---|
Use Scenario: Used across inductive loads (e.g., solenoids, relays, motor windings) to clamp back-EMF during switch-off. IC Role / Device Role / Timing Role: HS1JALH serves as passive unidirectional current path, conducting only when inductor voltage reverses polarity. Use Value: Its 600V VRRM and 35A IFSM safely absorb energy from 48V automotive inductors; 75ns trr minimizes voltage overshoot. | Use Scenario: Placed across switching FETs or transformers to suppress voltage spikes caused by leakage inductance. IC Role / Device Role / Timing Role: HS1JALH acts as fast-clamping element in RCD snubbers, turning on rapidly to divert transient energy. Use Value: 13pF CJ and low VF reduce snubber losses; AEC-Q101 rating ensures robustness in harsh automotive transients. |
| DC/DC Converter Output Rectifier | Automotive Power Supply |
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 3.3V–12V at ≤1A. IC Role / Device Role / Timing Role: HS1JALH conducts during transformer secondary positive half-cycle; blocks reverse current during reset phase. Use Value: 1.02V VF at 1A yields <1.1W conduction loss; 150°C TJ max supports operation near hot components in enclosed ECUs. | Use Scenario: Input rectification or auxiliary rail generation in body control modules, lighting controllers, and infotainment power supplies. IC Role / Device Role / Timing Role: HS1JALH provides primary AC/DC or DC/DC stage rectification with automotive-grade reliability and thermal stability. Use Value: Glass passivation and MSL-1 handling ensure field longevity; Thin SMA footprint fits tight board layouts common in automotive modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600V VRRM, 1A IF, 70ns trr, TO-277 package (larger footprint, higher RθJA) | Higher thermal resistance (70°C/W) limits power density; not AEC-Q101 qualified | Prefer HS1JALH where automotive qualification, Thin SMA footprint, or lower thermal resistance is required. |
| SB160-E3/5BT | 60V VRRM, 1A IF, SMA package, no AEC-Q101, 30ns trr | Insufficient voltage rating for 48V+ systems; unsuitable for automotive main rails | Only consider SB160-E3/5BT in low-voltage consumer DC/DC; HS1JALH is mandatory for 600V blocking and automotive compliance. |
Compared with STTH1L06S and SB160-E3/5BT, the HS1JALH uniquely combines AEC-Q101 qualification, 600V rating, Thin SMA form factor, and 29°C/W junction-to-lead thermal resistance-making it the only viable option for space- and reliability-constrained automotive 1A rectification.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the HS1JALH?
The HS1JALH has a VRRM of 600 V, verified per Taiwan Semiconductor's B2103 datasheet. This rating defines the highest reverse voltage the device can block repeatedly without breakdown, making it suitable for 48V battery systems and intermediate bus voltages in automotive and industrial DC/DC converters. Exceeding this value risks avalanche failure or permanent junction damage.
Is the HS1JALH qualified for automotive applications?
Yes, the HS1JALH is AEC-Q101 qualified, as explicitly stated in the official datasheet. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock-ensuring reliability in under-hood and cabin-mounted automotive electronics. The HS1JALH is not just "suitable for" but formally certified for automotive use.
What is the forward voltage drop of the HS1JALH at 1.0A and 25°C?
The HS1JALH exhibits a typical forward voltage (VF) of 1.02 V at 1.0A and 25°C, with a maximum of 1.70 V under the same conditions. This value is measured per pulse test (PW = 0.3ms) and directly impacts conduction loss-e.g., ~1.02W at full load-making it critical for thermal design in compact power stages.
Does the HS1JALH have a specified reverse recovery time (trr)?
Yes, the HS1JALH has a reverse recovery time (trr) of 75 ns, tested at IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This parameter is confirmed in the Electrical Specifications table of the B2103 datasheet and is essential for evaluating switching loss and EMI behavior in medium-frequency DC/DC topologies.
What package type does the HS1JALH use, and what are its key mechanical features?
The HS1JALH uses the Thin SMA package: a low-profile surface-mount outline with height ≤1.1 mm, glass-passivated die, matte tin-plated leads compliant with J-STD-002, and polarity indicated by cathode band. Its MSL-1 rating eliminates pre-bake requirements, and UL 94V-0 molding compound ensures flame resistance in safety-critical assemblies.
