Product details
Overview
S1JH from Taiwan Semiconductor is a surface-mount general-purpose silicon rectifier diode rated for 600 V repetitive peak reverse voltage, 1 A average forward current, and 40 A non-repetitive surge current, with a maximum forward voltage of 1.1 V at 1 A and 25°C - used in automotive lighting, DC-DC converters, and snubber circuits.
For engineers reviewing the S1JH datasheet, S1JH pinout, S1JH application, or S1JH equivalent, key selection criteria include its DO-214AC (SMA) package, AEC-Q101 qualification, 175°C maximum junction temperature, low leakage (≤1 µA at 25°C), and 1500 ns reverse recovery time under specified test conditions.
Technical Context
The S1JH is a single-die, glass-passivated, standard recovery rectifier optimized for cost-sensitive, medium-voltage power conversion where fast switching is not required. Its 1500 ns reverse recovery time and 12 pF junction capacitance reflect trade-offs favoring ruggedness and thermal stability over high-frequency performance.
Designed for automotive-grade reliability, it meets AEC-Q101 stress testing requirements and supports operation from –55°C to +175°C. Its DO-214AC (SMA) package delivers 27°C/W junction-to-lead thermal resistance and is compatible with automated SMT placement per J-STD-020 Level 1 moisture sensitivity.

| IF(AV) | 1 A - Continuous forward current rating at TA = 75°C; determines heatsink-free operation in low-power converters. |
| VF(max) | 1.1 V @ 1 A, 25°C - Forward conduction loss directly impacts efficiency and thermal rise in linear rectification paths. |
| IFSM | 40 A @ 8.3 ms - Surge capability enables robustness against inrush and transient overloads in automotive lighting drivers. |
| trr | 1500 ns - Standard recovery speed; suitable for ≤100 kHz switching topologies without significant switching loss penalties. |
| TJ(max) | +175°C - High junction temperature rating supports under-hood automotive environments and compact PCB layouts. |
| IR(max) | 1 µA @ 25°C - Low leakage ensures minimal standby power loss in battery-backed or always-on systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same VRRM (600 V), same IF (1 A), but faster trr (≈100 ns); higher VF (1.3 V typ) | Better suited for high-frequency PFC or resonant converters where switching loss dominates | Select STTH1R06 only if trr < 200 ns is required and higher conduction loss is acceptable |
| ON Semi MUR106 | Same VRRM (600 V), same IF (1 A), ultrafast trr (≈50 ns); VF ≈ 1.7 V max | Targeted at high-efficiency SMPS with >200 kHz operation; higher cost and thermal demand | Choose MUR106 when minimizing switching loss is critical and thermal design accommodates higher VF |
Compared with STTH1R06 and MUR106, the S1JH offers superior thermal robustness (175°C TJ(max)) and lower conduction loss (1.1 V max), making it optimal for automotive and industrial applications where reliability and steady-state efficiency outweigh ultrafast switching needs.

FAQ
What is the maximum junction temperature rating for the S1JH?
The S1JH has a maximum junction temperature (TJ(max)) of +175°C, enabling reliable operation in under-hood automotive environments and high-ambient industrial settings. This rating is validated per AEC-Q101 stress testing and allows the S1JH to sustain continuous 1 A forward current without external heatsinking at board-level ambient temperatures up to 75°C. Thermal derating curves confirm usable current capacity down to 0.5 A at 125°C ambient.
Is the S1JH pin-compatible with other diodes in the S1xH series?
Yes - all S1xH series diodes, including S1JH, share identical DO-214AC (SMA) package dimensions, lead spacing, and polarity marking (cathode band). The S1JH uses the same physical footprint and solder pad layout as S1AH through S1MH, allowing direct substitution within the same voltage grade group without PCB redesign. However, electrical parameters such as VRRM and IFSM differ across variants and must be verified for circuit compatibility.
Does the S1JH meet automotive qualification standards?
Yes, the S1JH is explicitly qualified to AEC-Q101 for stress testing including HTGB, HTRB, TCT, and mechanical shock. It is rated for automotive applications including LED headlamps, body control modules, and infotainment power supplies. Documentation confirms compliance with JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity - both essential for automotive SMT manufacturing.
What is the reverse recovery time (trr) specification for the S1JH?
The S1JH has a typical reverse recovery time (trr) of 1500 ns under the condition IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is measured using a standardized half-sine test waveform and reflects its classification as a standard-recovery rectifier. The 1500 ns trr makes the S1JH appropriate for line-frequency and low-to-mid frequency (<100 kHz) switching applications, where low conduction loss is prioritized over ultrafast switching.
Can the S1JH be used in snubber circuits?
Yes, the S1JH is explicitly recommended for snubber applications in the manufacturer's datasheet. Its 600 V VRRM provides margin against voltage overshoot, while its 40 A IFSM handles repetitive energy absorption from inductive switching events. The 1500 ns trr balances clamping effectiveness with manageable EMI generation, and its glass-passivated junction ensures long-term stability in high-dV/dt environments typical of IGBT and MOSFET snubbers.
