Product details
Overview
S1JHR3G from Taiwan Semiconductor is a surface-mount general-purpose silicon rectifier diode with 600 V repetitive peak reverse voltage (VRRM), 1 A average forward current (IF), and DO-214AC (SMA) package. It features glass-passivated junction, low forward voltage drop (VF ≤ 1.1 V at IF = 1 A, TJ = 25°C), and 1500 ns reverse recovery time (trr), suited for DC-DC converters and snubber circuits in industrial power supplies.
For engineers reviewing the S1JHR3G datasheet, S1JHR3G pinout, S1JHR3G application, or S1JHR3G equivalent, key selection factors include its 600 V VRRM rating, 40 A non-repetitive surge capability (IFSM), 175°C maximum junction temperature, thermal resistance (RθJA = 75°C/W), and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
The S1JHR3G is a single-die, unidirectional silicon PN junction rectifier optimized for switching-mode power conversion. Its 1500 ns reverse recovery time supports moderate-frequency operation up to ~50 kHz, while the glass-passivated chip junction ensures stable performance under humidity and thermal cycling.
Thermal design is enabled by RθJL = 27°C/W (junction-to-lead) and RθJA = 75°C/W (junction-to-ambient), allowing 1 A continuous conduction at ambient temperatures up to 85°C with standard PCB copper area. The device operates across –55°C to +175°C junction range and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in DC-DC flyback or buck converter output stage |
| IF(AV) | 1 A - Continuous average forward current at TA = 75°C with adequate PCB copper; derates linearly above 75°C |
| VF | ≤1.1 V @ IF = 1 A, TJ = 25°C - Low conduction loss enabling >85% efficiency in low-power SMPS designs |
| IFSM | 40 A @ 8.3 ms half-sine - Withstands inrush surges during cold-start of AC/DC adapters or LED drivers |
| trr | 1500 ns - Enables use in <50 kHz switching topologies without excessive switching loss or EMI |
| TJ max | +175°C - Supports high-temperature environments such as enclosed industrial enclosures or automotive under-hood proximity |
| CJ | 12 pF @ 1 MHz, VR = 4 V - Minimizes capacitive coupling in high-speed snubber networks and gate-drive isolation |

Applications
| DC-DC Converter Output Rectification | Snubber Network Diode |
|---|---|
Use Scenario: Used as secondary-side freewheeling diode in isolated flyback or forward converters delivering 5–24 V at ≤1 A. IC Role / Device Role / Timing Role: Unidirectional current path enabling energy transfer during MOSFET off-time; blocks reverse voltage during primary switch conduction. Use Value: 600 V VRRM safely absorbs reflected voltage spikes; 1.1 V VF minimizes conduction loss and thermal stress at 1 A load. | Use Scenario: Placed across switching FETs or transformers to suppress voltage overshoot during turn-off transitions. IC Role / Device Role / Timing Role: Clamps transient voltage spikes by conducting only when reverse voltage exceeds VRRM threshold. Use Value: 1500 ns trr ensures fast turn-on during spike events; 12 pF CJ avoids resonant ringing with snubber RC components. |
| LED Driver Secondary Rectification | Industrial Control Power Supply Input Stage |
Use Scenario: Rectifies transformer-isolated auxiliary winding output powering LED string bias or control ICs. IC Role / Device Role / Timing Role: Converts AC auxiliary winding output to regulated DC for logic-level circuitry. Use Value: 175°C TJ max allows operation near hot LED heatsinks; moisture level 1 simplifies manufacturing flow. | Use Scenario: Front-end rectifier in 24 V or 48 V industrial PLC power modules handling intermittent loads. IC Role / Device Role / Timing Role: Provides unregulated DC bus from bridge or center-tapped transformer secondary. Use Value: 40 A IFSM withstands motor startup surges; UL 94V-0 package meets industrial enclosure flammability requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR160 | VRRM = 600 V, IF = 1 A, trr = 75 ns - ultrafast recovery vs. S1JHR3G's 1500 ns | Better suited for >100 kHz SMPS; higher cost and tighter layout constraints due to faster switching | Select MUR160 only if trr < 100 ns is required; S1JHR3G preferred for cost-sensitive ≤50 kHz designs |
| Vishay VS-1N4007-M3/54 | VRRM = 1000 V, IF = 1 A, trr ≈ 30 µs - general-purpose slow recovery; no glass passivation | Higher leakage (>50 µA @ 125°C), not moisture level 1 rated; unsuitable for automated SMT without pre-bake | VS-1N4007-M3/54 may be used in non-SMT legacy repairs; S1JHR3G offers superior manufacturability and thermal margin |
Compared with MUR160 and VS-1N4007-M3/54, the S1JHR3G delivers optimal balance of 600 V blocking, 1 A current handling, 1500 ns recovery, and SMT-ready reliability-making it ideal for cost-constrained industrial and lighting power supplies where ultrafast switching is unnecessary.

FAQ
What is the maximum junction temperature rating for the S1JHR3G?
The S1JHR3G has a maximum junction temperature (TJ max) of +175°C, enabling operation in thermally demanding environments such as enclosed industrial power supplies or near high-power LED arrays. This rating is validated per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision S2102, and allows for extended lifetime when operated within thermal derating curves.
Is the S1JHR3G suitable for automated SMT assembly without baking?
Yes, the S1JHR3G is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be placed directly onto PCBs and reflowed without pre-baking. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the DO-214AC (SMA) package is optimized for pick-and-place compatibility in high-volume manufacturing.
What does the 'J' in S1JHR3G indicate?
The 'J' in S1JHR3G denotes the 600 V repetitive peak reverse voltage (VRRM) rating within the S1x rectifier series. Per Taiwan Semiconductor's ordering nomenclature, S1A = 50 V, S1B = 100 V, ..., S1J = 600 V. The 'HR3G' suffix indicates tape-and-reel packaging (7,500 pcs/reel) and green halogen-free compound.
How does the reverse recovery time of the S1JHR3G affect its use in switching power supplies?
The S1JHR3G has a reverse recovery time (trr) of 1500 ns, making it appropriate for switching frequencies up to approximately 50 kHz. At higher frequencies, increased switching loss and EMI may occur. For designs exceeding 50 kHz, consider ultrafast alternatives like MUR160; for ≤50 kHz applications, the S1JHR3G provides robust performance with lower cost and wider thermal margin.
Does the S1JHR3G meet environmental compliance standards?
Yes, the S1JHR3G is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and terminals pass JESD201 Class 2 whisker testing-ensuring suitability for environmentally regulated industrial and commercial end equipment.
