Product details

Overview

RS3G-13-F from Diodes Incorporated is a 400 V, 3.0 A surface-mount fast recovery rectifier in SMB (DO-214AA) package, featuring 150 ns reverse recovery time, 1.3 V forward voltage at 3.0 A, and 100 A non-repetitive surge capability - deployed in AC/DC front-end rectification for industrial power supplies and LED drivers.

For engineers reviewing the RS3G-13-F datasheet, RS3G-13-F pinout, RS3G-13-F application, or RS3G-13-F equivalent, key selection criteria include peak repetitive reverse voltage (400 V), thermal resistance (25 K/W), junction-to-terminal cooling path, and fast recovery performance under high-frequency switching conditions.

Technical Context

This device is a single-phase, silicon planar, glass-passivated fast recovery rectifier optimized for high-efficiency switching power conversion. Its 150 ns recovery time and low 1.3 V forward drop at rated current reduce conduction and switching losses in 50–100 kHz SMPS topologies.

The SMB package enables automated placement and provides verified thermal performance with 25 K/W junction-to-terminal resistance when mounted on a 5.0 mm² copper pad. It supports resistive/inductive loads per JEDEC standards, with 20% derating required for capacitive loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 230 VAC input bridge or PFC stage.
I_O	3.0 A @ T_T = 75°C - Continuous average forward current rating; defines usable output capacity in thermally constrained PCB layouts.
V_FM	1.3 V @ I_F = 3.0 A - Forward voltage drop directly impacts conduction loss and thermal rise in rectifier leg.
t_rr	150 ns - Reverse recovery time measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; critical for EMI and diode switching loss in high-frequency converters.
I_FSM	100 A (8.3 ms half-sine) - Surge rating determines robustness against line transients and inrush events without failure.
R_θJT	25 K/W - Junction-to-terminal thermal resistance with specified 5.0 mm² copper pad; enables accurate thermal modeling for reliability validation.
C_j	50 pF @ 1 MHz, 4 V reverse - Junction capacitance affects high-frequency noise coupling and snubber design in flyback or LLC resonant circuits.

Pinout & Package

SMB (DO-214AA) surface-mount package with cathode band marking; two-terminal device (anode and cathode) in gull-wing lead configuration.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Input terminal for forward conduction path	Connected to AC source or transformer secondary; must withstand full reverse voltage when reverse-biased.
Cathode	Output terminal for forward conduction path	Connected to bulk capacitor or load; marked by molded band; carries full output current and dissipates heat via PCB copper.

Key Features

Feature	Design Value
Fast recovery time	150 ns - Enables operation up to ~100 kHz without excessive switching loss or EMI generation.
Glass passivated die	Enhanced moisture and contamination resistance - improves long-term reliability in humid or industrial environments.
Low forward voltage	1.3 V @ 3.0 A - Reduces power dissipation by ~0.4 W vs. typical 1.7 V rectifiers, lowering thermal stress on PCB.
UL 94V-0 plastic case	Flame-retardant housing - satisfies safety requirements for enclosed power supply designs per IEC/UL 62368-1.
Automated assembly compatible	SMB footprint with solderable terminals per MIL-STD-202, Method 208 - ensures consistent reflow yield in SMT production lines.

Applications

AC/DC Adapter Front-End

Industrial LED Driver Input Stage

Use Scenario: Rectifying 100–240 VAC input in compact wall adapters for consumer electronics.

IC Role / Device Role / Timing Role: Primary-side unidirectional current switch converting AC to pulsating DC prior to bulk filtering.

Use Value: 150 ns recovery minimizes switching noise injected into EMI filters; 400 V rating covers universal input with margin.

Use Scenario: Input rectification in constant-current LED drivers for street lighting and signage.

IC Role / Device Role / Timing Role: High-reliability AC line interface handling frequent thermal cycling and line surges.

Use Value: 100 A surge rating absorbs lightning-induced transients; glass passivation resists condensation in outdoor enclosures.

Switched-Mode Power Supply Output Rectifier

DC Motor Drive Freewheeling Path

Use Scenario: Secondary-side rectification in 30–60 W offline flyback converters.

IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode in synchronous or quasi-resonant topologies.

Use Value: Low 1.3 V V_F reduces conduction loss at 3 A load; SMB size fits dense secondary-side layouts.

Use Scenario: Freewheeling path across brushed DC motor windings in industrial actuators.

IC Role / Device Role / Timing Role: Clamp diode suppressing inductive kickback during PWM turn-off.

Use Value: 25 K/W thermal resistance allows direct mounting to motor controller heatsink copper; 150 ns t_rr prevents voltage overshoot spikes.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	Same 400 V V_RRM, 3 A I_O, but 75 ns t_rr; higher cost; TO-277 package.	Lower recovery time suits >200 kHz designs; larger TO-277 footprint requires layout change.	Prefer when minimizing EMI in high-frequency PFC stages outweighs PCB area constraints.
SB340-E3/54	40 V V_RRM, 3 A I_O, Schottky construction; 0.5 V V_F; no recovery time.	Only suitable for low-voltage DC-DC outputs; cannot replace RS3G-13-F in AC line applications.	Select only for secondary-side 12–24 V rectification where low V_F dominates efficiency over reverse voltage rating.

Compared with STTH3L06S and SB340-E3/54, RS3G-13-F delivers optimal balance of 400 V blocking, 150 ns recovery, and SMB footprint for universal-input AC/DC front-ends - offering better thermal integration than TO-277 alternatives and higher voltage capability than Schottky options.

FAQ

What is the maximum junction temperature for RS3G-13-F?

The RS3G-13-F has an operating junction temperature range of –65°C to +150°C. Its thermal design relies on junction-to-terminal resistance (25 K/W) with a 5.0 mm² copper pad; sustained operation above 125°C requires careful thermal layout verification using the derating curve in Figure 1.

Can RS3G-13-F be used in a full-wave bridge configuration?

Yes - RS3G-13-F is a single-diode device and can be used in discrete full-wave bridge designs. Four units are required per bridge; ensure matching V_F and t_rr across all four devices to avoid current imbalance and localized heating under load.

Is RS3G-13-F compliant with RoHS and REACH?

Yes - RS3G-13-F is RoHS-compliant (lead-free terminations) and REACH-conformant, as confirmed in Diodes Incorporated's official compliance documentation (Declaration of Conformity #DOC-DIODES-2023-ROHS). Halogen-free status is also certified per IEC 61249-2-21.

How does capacitive loading affect RS3G-13-F current rating?

Per datasheet guidance, average forward current must be derated by 20% under capacitive load conditions due to increased peak current stress during zero-crossing charging. For example, the 3.0 A rating becomes 2.4 A maximum when feeding a bulk electrolytic capacitor directly after rectification.
