Product details

Overview

RS1G-13-F from Diodes Incorporated is a 1.0A surface-mount fast recovery rectifier in SMA package, rated for 400V peak repetitive reverse voltage (V_RRM), with 1.3V max forward voltage at 1.0A and 150ns reverse recovery time (t_RR). It delivers high-efficiency AC/DC conversion in compact power supplies for consumer adapters and industrial SMPS.

For engineers reviewing the RS1G-13-F datasheet, RS1G-13-F pinout, RS1G-13-F application, or RS1G-13-F equivalent, key selection criteria include its 400V blocking capability, 30A surge rating, RoHS-compliant lead-free finish, and thermal resistance of 20°C/W - critical for thermally constrained board-level designs.

Technical Context

This device operates as a unidirectional silicon PN junction rectifier optimized for fast switching in single-phase bridge and flyback topologies. Its glass-passivated die construction ensures stable reverse leakage (<5µA at 25°C) and robust surge tolerance up to 30A (8.3ms half-sine).

The 150ns reverse recovery time enables operation at switching frequencies up to ~100kHz without excessive switching loss, while its 15pF junction capacitance minimizes high-frequency noise coupling in EMI-sensitive applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Sustains 400V reverse bias without breakdown; suitable for 230VAC input-derived rails with safety margin.
I_O	1.0 A - Continuous average forward current at T_T = +120°C; defines usable DC output capacity in thermally managed layouts.
V_FM	1.3 V max @ 1.0A - Limits conduction loss to ≤1.3W per diode; critical for efficiency in low-voltage, high-current secondary-side rectification.
t_RR	150 ns - Enables efficient operation in 50–100kHz SMPS without significant reverse recovery loss or ringing.
R_θJT	20 °C/W - Junction-to-terminal thermal resistance; allows direct PCB copper pour thermal path design without heatsink.
I_FSM	30 A - Withstands 8.3ms line surges (e.g., cold-start inrush), supporting robust input stage protection.
C_T	15 pF @ 4V, 1MHz - Low junction capacitance reduces capacitive coupling noise in high-dv/dt gate-drive or feedback paths.

Pinout & Package

SMA package: surface-mount, molded plastic case (UL 94V-0), cathode indicated by band on top surface; terminals are matte tin annealed over copper alloy leadframe.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry node	Connected to transformer secondary or switch node; must handle full load current and surge transients.
Cathode	Forward current exit node / reverse voltage reference	Connected to output capacitor positive rail; polarity marking (band) prevents assembly reversal.

Key Features

Feature	Design Value
Glass passivated die	Eliminates need for conformal coating; ensures long-term reliability under humidity and contamination exposure.
Fast recovery (150ns)	Reduces switching loss and EMI generation in 50–100kHz flyback and forward converters.
30A surge rating	Supports repeated cold-start and lightning-induced line surges without degradation.
RoHS & Halogen-free	Meets EU Directive 2015/863/EU; <900ppm Br/Cl, <1000ppm Sb - required for green electronics compliance.

Applications

Industrial SMPS

Use Scenario: 5–24V, 0.5–1.0A wall adapters for IoT sensors and USB-C PD accessories.

IC Role / Device Role / Timing Role: Secondary-side output rectifier in discontinuous conduction mode (DCM) flyback.

Use Value: 1.3V V_FM limits conduction loss to <1.3W; 150ns t_RR avoids cross-conduction loss during MOSFET turn-on.

Use Scenario: 12–48V regulated outputs in DIN-rail mounted PLC power modules.

IC Role / Device Role / Timing Role: Input bridge rectifier in 230VAC front-end with PFC pre-regulator.

Use Value: 400V V_RRM provides 2× safety margin over 230VAC peak (325V); 30A I_FSM withstands motor startup surges.

Automotive Infotainment

Use Scenario: Constant-current LED drivers for commercial signage with universal AC input.

IC Role / Device Role / Timing Role: Primary-side rectifier in isolated buck-boost topology.

Use Value: 20°C/W R_θJT enables direct thermal pad attachment to PCB ground plane, maintaining T_J < 125°C at full load.

IC Role / Device Role / Timing Role: Reverse-polarity protection and load dump clamp diode.

Use Value: 15pF C_T minimizes capacitive coupling into sensitive analog audio paths; RoHS/halogen-free meets automotive ELV directive.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06S	600V V_RRM, 1.7V V_FM, 125ns t_RR, TO-277 package	Higher voltage rating but higher forward drop; requires different footprint and thermal layout.	Select when >400V blocking is needed and board space permits larger package.
MBR140SFT1G	Schottky, 40V V_RRM, 0.55V V_FM, no reverse recovery	Lower voltage, zero t_RR, but unsuitable for 230VAC-derived inputs.	Use only in low-voltage DC-DC outputs where ultra-low V_F outweighs voltage limitation.

Compared with STTH1L06S and MBR140SFT1G, RS1G-13-F uniquely balances 400V capability, 1.3V conduction loss, and SMA footprint - making it optimal for cost- and space-constrained 230VAC-input adapters requiring fast but not ultra-fast recovery.

FAQ

What is the maximum operating temperature for RS1G-13-F?

The RS1G-13-F has an operating junction temperature range of –65°C to +150°C. Its thermal resistance (R_θJT = 20°C/W) means that at 1.0A continuous current and 1.3V forward drop, junction temperature rise above terminal temperature is ~26°C - allowing safe operation up to +124°C ambient when properly mounted on ≥1 cm² copper pour.

Is RS1G-13-F suitable for use in a bridge rectifier configuration?

Yes - RS1G-13-F is rated for single-phase, half-wave rectification but is commonly used in full-wave bridge configurations (e.g., GBU6K replacement with four units). Its 400V V_RRM supports 230VAC input (325V peak), and its 30A I_FSM handles typical bridge surge currents when paralleled or used in standard 4-diode layouts.

Does RS1G-13-F have a specified reverse recovery charge (Q_rr)?

No - the DS15002 datasheet does not specify Q_rr. Only t_RR = 150ns is provided (measured at I_F = 0.5A, I_R = 1.0A, I_RR = 0.25A). For designs sensitive to recovery charge, empirical measurement or simulation using the provided t_RR and C_T = 15pF is recommended.

Can RS1G-13-F be substituted with a Schottky diode?

Only in low-voltage applications (<60V DC output). RS1G-13-F's 400V rating makes it incompatible with most Schottky diodes, which typically max out at 200V. Substituting with a Schottky like MBR140SFT1G would cause catastrophic failure under 230VAC input conditions due to insufficient V_RRM.
