Product details
Overview
RS1J from Taiwan Semiconductor is a fast recovery surface-mount rectifier diode with 600 V repetitive peak reverse voltage (VRRM), 1 A average forward current (IF), 30 A peak surge current (IFSM), and 250 ns reverse recovery time (trr) at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A - used in DC-DC converters and snubber circuits for high-efficiency switching power supplies.
For engineers reviewing the RS1J datasheet, RS1J pinout, RS1J application, or RS1J equivalent, key selection criteria include its DO-214AC (SMA) package, 1.3 V max forward voltage at 1 A, 5 µA max reverse leakage at 25°C, 105 °C/W junction-to-ambient thermal resistance, and suitability for automated SMT assembly in industrial and lighting power stages.
Technical Context
The RS1J operates as a single-die, unidirectional fast recovery rectifier optimized for high-frequency switching applications. Its glass-passivated junction ensures stable performance under thermal cycling, while the DO-214AC (SMA) package supports reflow soldering per J-STD-002 and meets UL 94V-0 flammability requirements.
With a maximum junction temperature of 175°C and thermal resistance RθJA = 105 °C/W, the RS1J delivers reliable conduction in compact layouts. Its 250 ns trr enables reduced switching losses compared to general-purpose rectifiers, and its 5 µA reverse leakage at 25°C supports low-power standby operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in flyback or boost converters |
| IF | 1 A - continuous average forward current rating; sets steady-state power handling capability in DC-DC output stage |
| trr | 250 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; determines switching loss and EMI profile in >100 kHz topologies |
| VF (max) | 1.3 V at IF = 1 A, TJ = 25°C - forward voltage drop directly impacts conduction loss and thermal design margin |
| IR (max) | 5 µA at VR = 600 V, TJ = 25°C - low leakage preserves efficiency in high-impedance bias or hold-up circuits |
| RθJA | 105 °C/W - junction-to-ambient thermal resistance; used to calculate temperature rise in natural-convection PCB layouts |

|---|---|
Use Scenario: Used as secondary-side rectifier in isolated flyback or forward converters delivering 5–24 V at up to 1 A. IC Role / Device Role / Timing Role: Unidirectional current path enabling energy transfer from transformer to output capacitor during switch-off phase. Use Value: 250 ns trr minimizes reverse recovery loss, improving overall converter efficiency by ~0.5–1.2% vs. slower rectifiers at 250 kHz. | Use Scenario: Placed across MOSFET or IGBT switches to absorb inductive turn-off energy in motor drives and inverters. IC Role / Device Role / Timing Role: Fast clamping element that conducts transient voltage spikes before they exceed device breakdown limits. Use Value: Low VF and fast trr allow rapid energy dissipation with minimal voltage overshoot, protecting switching devices from avalanche stress. |
| LED Driver Power Stage | Switching Mode Lighting Ballast |
Use Scenario: Rectifies high-frequency AC from resonant half-bridge in constant-current LED drivers for street lighting. IC Role / Device Role / Timing Role: High-voltage output rectifier converting switched AC to regulated DC for LED string bias. Use Value: 600 V VRRM withstands reflected transients in magnetic-resonant topologies; 175°C TJ max supports sealed fixture thermal environments. | Use Scenario: Integrated into electronic ballasts for fluorescent and HID lamps operating at 20–60 kHz. IC Role / Device Role / Timing Role: Input-stage rectifier feeding high-frequency inverter, requiring low leakage and stable performance over life. Use Value: 5 µA IR at 25°C prevents standby current drift; glass passivation ensures 10+ year reliability under cyclic thermal stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | 600 V VRRM, 1 A IF, 150 ns trr, TO-277 package | Lower trr but larger footprint and higher RθJA (120 °C/W); requires layout revision | Preferred where faster recovery is critical and board space allows TO-277 mounting |
| ES1J | 600 V VRRM, 1 A IF, 35 ns trr, DO-214AC (SMA) package | Ultra-fast recovery but higher VF (1.7 V typ) and lower IFSM (25 A) | Selected when minimizing switching loss dominates over conduction loss in high-frequency designs |
Compared with STTH1R06U and ES1J, the RS1J offers balanced trade-offs: moderate trr (250 ns), low VF (≤1.3 V), DO-214AC compatibility, and robust surge rating (30 A IFSM), making it optimal for cost-sensitive, thermally constrained 100–300 kHz power supplies.

FAQ
What is the maximum junction temperature rating for the RS1J?
The RS1J has a maximum junction temperature (TJ) of +175°C, verified per absolute maximum ratings in the official TSC datasheet M2304. This rating enables operation in thermally demanding environments such as enclosed LED drivers or industrial power supplies. Derating curves confirm usable current capacity down to 0.5 A at 125°C ambient, assuming standard PCB copper area. The RS1J must not be operated beyond this limit to ensure long-term reliability.
Does the RS1J have a RoHS-compliant and halogen-free construction?
Yes, the RS1J is explicitly certified RoHS compliant and halogen-free per TSC documentation M2304. Its molding compound meets UL 94V-0 flammability standards, and terminals are matte tin plated per J-STD-002 solderability requirements. These attributes satisfy environmental compliance mandates for CE-marked industrial equipment and consumer electronics. The RS1J carries no exemptions and is fully compliant without substitution.
What is the reverse recovery time (trr) specification for the RS1J?
The RS1J has a reverse recovery time (trr) of 250 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per TSC datasheet M2304. This value is confirmed in the Electrical Specifications table and distinguishes RS1J from RS1G (150 ns) and RS1K (500 ns) in the same family. The RS1J's trr directly impacts switching loss in hard-switched topologies above 100 kHz.
Is the RS1J pin-compatible with other devices in the RS1x series?
No - all RS1x devices share the identical DO-214AC (SMA) package and anode/cathode terminal configuration, making them mechanically and electrically pin-compatible. The RS1J uses the same footprint, polarity marking, and solder pad layout as RS1A through RS1M. However, electrical parameters including VRRM, trr, and IR differ significantly across the series, so direct substitution requires validation against circuit voltage and timing requirements.
What is the forward voltage (VF) of the RS1J at rated current?
The RS1J exhibits a maximum forward voltage (VF) of 1.3 V at 1 A forward current and 25°C junction temperature, per the Electrical Specifications table in TSC datasheet M2304. This value is measured under pulse conditions (PW = 0.3 ms) and represents worst-case conduction loss. At elevated temperatures or lower currents, VF decreases slightly; the RS1J's typical VF is approximately 1.05 V under the same conditions.
