Product details
Overview
S1GH from Taiwan Semiconductor is a 1 A, 400 V surface-mount silicon rectifier diode in DO-214AC (SMA) package, featuring glass-passivated junction, AEC-Q101 qualification, and 1.1 V max forward voltage at 1 A. It serves as a general-purpose power rectifier in automotive lighting and DC-DC converters.
For engineers reviewing the S1GH datasheet, S1GH pinout, S1GH application, or S1GH equivalent, key selection criteria include peak reverse voltage (400 V), surge current rating (30 A), thermal resistance (27 °C/W junction-to-lead), junction temperature range (–55 to +175 °C), and RoHS/halogen-free compliance.
Technical Context
The S1GH is a single-die, standard recovery rectifier with 1500 ns reverse recovery time under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A conditions. Its glass-passivated junction ensures stable performance in humid environments and supports automated placement.
Thermal design is enabled by low RθJL (27 °C/W) and RθJA (75 °C/W), while the DO-214AC (SMA) package provides UL 94V-0 flammability rating and matte tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in bridge or flyback snubber circuits. |
| IF | 1 A continuous - Rated average forward current; determines steady-state power dissipation capability. |
| IFSM | 30 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush tolerance in automotive load switching. |
| VF max | 1.1 V @ 1 A, 25°C - Forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle rectification. |
| TJ max | +175°C - Maximum junction temperature enables operation in under-hood automotive environments without derating. |
| CJ | 12 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency switching noise and EMI in SMPS feedback paths. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, single-anode/single-cathode configuration with cathode band marking. Weight: 0.060 g. Moisture sensitivity level: J-STD-020 Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of AC source or switch node; polarity must match PCB silkscreen. |
| Cathode | Forward current exit point | Marked by band; connects to output rail or filter capacitor positive; critical for correct rectifier orientation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
| Glass-passivated junction | Provides hermetic protection against humidity-induced leakage and long-term parameter drift in harsh environments. |
| Low VF (1.1 V max) | Reduces conduction losses by ~15% vs. comparable 1A rectifiers, lowering thermal load in space-constrained layouts. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally regulated end equipment. |
Applications
| Automotive LED Lighting | DC-DC Converter Output Rectification |
|---|---|
Use Scenario: Rectifying switched AC input in constant-current LED driver modules for headlamps and DRLs. IC Role / Device Role / Timing Role: Power rectifier converting transformer secondary output to regulated DC bus. Use Value: AEC-Q101 qualification and 175°C TJ ensure reliability in engine bay ambient temperatures up to 125°C. | Use Scenario: Secondary-side rectification in isolated 12 V → 5 V/3.3 V buck-derived converters for infotainment ECUs. IC Role / Device Role / Timing Role: Uncontrolled rectifier in flyback or forward topology output stage. Use Value: 30 A IFSM withstands startup surges; 1.1 V VF minimizes voltage drop across output filter inductors. |
| Snubber Network Protection | Industrial Power Supply Input Stage |
Use Scenario: Clamping voltage spikes across MOSFET drains in motor drive inverters using RC snubbers. IC Role / Device Role / Timing Role: Fast-recovery diode absorbing transient energy during switching transitions. Use Value: 1500 ns trr balances snubber efficiency and EMI generation-slower than ultrafast types but sufficient for 20–100 kHz PWM. | Use Scenario: Input bridge rectification in universal-input (85–265 VAC) industrial SMPS for PLC I/O modules. IC Role / Device Role / Timing Role: General-purpose rectifier handling line-frequency full-wave conversion. Use Value: 400 V VRRM provides 2× safety margin over 265 VAC peak (375 V), supporting robust design margins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR140 | Ultrafast recovery (50 ns), higher VF (1.3 V), same 400 V VRRM, DO-41 through-hole | Better for high-frequency SMPS; unsuitable for SMT-only assembly | Select when EMI reduction and faster switching outweigh soldering process constraints. |
| Vishay VS-1N4007HM3/54 | Standard recovery (30 µs), 1000 V VRRM, 1 A IF, DO-214AC, halogen-free | Higher voltage margin but slower recovery; less efficient in mid-frequency converters | Prefer where cost-sensitive designs require ≥600 V standoff and do not demand fast trr. |
Compared with MUR140 and VS-1N4007HM3/54, the S1GH delivers optimal balance of AEC-Q101 compliance, surface-mount compatibility, 400 V rating, and 1.1 V low forward drop-making it ideal for automotive and industrial SMT power supplies where reliability and thermal efficiency are prioritized over ultrafast switching.

FAQ
What is the maximum junction temperature rating for the S1GH?
The S1GH has a maximum junction temperature (TJ) of +175°C, enabling reliable operation in under-hood automotive applications and high-ambient industrial power supplies. This rating is validated per JEDEC standards and supported by its 27 °C/W junction-to-lead thermal resistance. The S1GH maintains stable electrical parameters across this full range when properly heatsinked.
Is the S1GH suitable for automotive applications?
Yes, the S1GH is AEC-Q101 qualified and designed for automotive use, including LED lighting, body control modules, and DC-DC converters. Its glass-passivated junction, halogen-free construction, and –55°C to +175°C operating range meet stringent automotive environmental requirements. The S1GH is explicitly listed in TSC's AEC-Q101 product documentation as qualified for automotive-grade deployment.
What does the "G" in S1GH indicate?
The "G" in S1GH denotes the device's rated repetitive peak reverse voltage: 400 V. Per TSC's S1xH series ordering convention, "A" = 50 V, "B" = 100 V, "D" = 200 V, "G" = 400 V, "J" = 600 V, "K" = 800 V, and "M" = 1000 V. This coding is laser-marked on the DO-214AC (SMA) package as "S1G".
What is the reverse recovery time (trr) of the S1GH?
The S1GH has a typical reverse recovery time (trr) of 1500 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is specified in the official TSC datasheet Version A2102 and reflects its standard recovery behavior-suitable for line-frequency and mid-frequency (≤100 kHz) rectification, but not ultrafast SMPS topologies.
Does the S1GH have RoHS and halogen-free compliance?
Yes, the S1GH is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These certifications are confirmed in the TSC S1xH datasheet (Version A2102) and verified via material declarations. The S1GH uses matte tin-plated leads and UL 94V-0 molding compound, supporting environmentally regulated end equipment.
