Product details

Overview

RS1D-13 from Diodes Incorporated is a surface-mount fast recovery rectifier diode rated for 200 V peak repetitive reverse voltage, 1.0 A average forward current, and 30 A non-repetitive surge current, with 150 ns reverse recovery time and 1.3 V forward voltage drop at 1.0 A - used in AC/DC input stages of compact power adapters and DC-DC converter front-ends.

For engineers reviewing the RS1D-13 datasheet, RS1D-13 pinout, RS1D-13 application, or RS1D-13 equivalent, key selection criteria include fast recovery performance (t_RR = 150 ns), thermal resistance (R_θJT = 20 °C/W), RoHS-compliant lead-free finish, and SMA package compatibility with automated SMT assembly.

Technical Context

This device operates as a unidirectional silicon PN junction rectifier optimized for high-frequency switching power supplies. Its glass-passivated die construction ensures stable reverse leakage (I_RM ≤ 5.0 µA at 25°C) and robust surge capability (30 A, 8.3 ms half-sine).

The SMA package enables low-profile mounting with defined thermal path to PCB copper; junction-to-terminal thermal resistance of 20 °C/W supports operation up to +120°C terminal temperature under full-rated current.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Withstands transient spikes up to 200 V in bridge or single-diode rectification without breakdown.
I_O	1.0 A @ T_T = +120°C - Continuous DC output current capability when mounted on thermally adequate PCB copper.
t_RR	150 ns - Enables efficient operation in 100–500 kHz SMPS designs by minimizing switching loss during commutation.
V_F	1.3 V @ I_F = 1.0 A - Low conduction loss improves efficiency in low-voltage, high-current secondary-side rectification.
I_FSM	30 A - Survives inrush surges common during cold-start of offline power supplies with capacitive input filters.
R_θJT	20 °C/W - Direct thermal path from junction to soldered terminal allows accurate thermal design using PCB copper area as heatsink.

IC Role / Device Role / Timing Role: Primary-side fast recovery rectifier in voltage-doubler or bridge configuration.

Use Value: 150 ns t_RR minimizes switching loss during 50/60 Hz rectification with high-frequency ripple content.

Use Scenario: Input rectification in isolated flyback or forward converters operating at 100–300 kHz.

IC Role / Device Role / Timing Role: Secondary-side synchronous or standard rectifier handling pulsed DC input before bulk filtering.

Use Scenario: DIN-rail mounted 24 V power modules powering PLC I/O and sensors in factory environments.

IC Role / Device Role / Timing Role: Input rectifier subjected to line transients and repeated cold starts.

Use Value: 30 A I_FSM rating ensures reliability during repeated inrush events across wide ambient temperature range (−40°C to +85°C).

Use Scenario: Constant-voltage LED drivers for commercial lighting with EMI-sensitive environments.

Use Value: Low 15 pF typical capacitance reduces high-frequency noise coupling into downstream PWM circuitry.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R02U	Same 200 V V_RRM, but t_RR = 35 ns and V_F = 1.15 V @ 1 A - lower loss, tighter tolerance.	Preferred where higher efficiency or tighter thermal margin is required in space-constrained designs.	Select if system-level efficiency gain justifies cost premium and layout change for TO-277 package.
MBR120ESFT1G	100 V V_RRM, Schottky architecture - zero reverse recovery, but limited to ≤120 V circuits.	Only suitable for low-line or DC-fed inputs; cannot replace RS1D-13 in universal AC input stages.	Choose only for 12 V or 24 V DC-DC front-ends where ultra-low V_F (0.52 V) outweighs voltage limitation.

Compared with STTH1R02U and MBR120ESFT1G, RS1D-13 offers optimal balance of voltage rating, recovery speed, and cost for universal-input AC/DC applications - its 200 V rating and 150 ns t_RR provide margin for transient suppression while maintaining SMT compatibility and thermal predictability in SMA footprint.

FAQ

What is the maximum junction temperature for RS1D-13?

The RS1D-13 has an operating junction temperature range of −65°C to +150°C. Its thermal resistance (R_θJT = 20 °C/W) means that at 1.0 A continuous current and 25°C ambient, junction temperature rise is approximately 20°C above terminal temperature - allowing safe operation up to +120°C terminal temperature per derating curve.

Is RS1D-13 suitable for use in a full-wave bridge configuration?

Yes - RS1D-13 is commonly used in discrete full-wave bridge rectifiers due to its 200 V V_RRM, 30 A I_FSM, and matched electrical characteristics across the RS1x family. Four RS1D-13 devices can form a compact, high-reliability bridge for 100–120 V_AC inputs with sufficient voltage margin.

Does RS1D-13 require a heatsink in typical applications?

No external heatsink is required when mounted on ≥1 cm² of 1 oz copper on FR-4 PCB. The 20 °C/W R_θJT and 1.0 A I_O rating assume adequate PCB copper area acts as thermal mass; thermal simulation or measurement is recommended for >0.8 A continuous loads in enclosed or high-ambient environments.

How does RS1D-13 differ from RS1D-13-F?

RS1D-13 and RS1D-13-F are identical electrically and mechanically; the "-F" suffix explicitly denotes RoHS-compliant, lead-free, halogen-free ("Green") construction per Diodes Incorporated's internal coding. Both part numbers refer to the same SMA-packaged, 200 V fast recovery rectifier with identical datasheet specifications and marking.
