Product details

Overview

RS3GB-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 - used in AC/DC front-end rectification for switch-mode power supplies and offline adapters.

For engineers reviewing the RS3GB-13-F datasheet, RS3GB-13-F pinout, RS3GB-13-F application, or RS3GB-13-F equivalent, key selection criteria include peak repetitive reverse voltage (400 V), average output current rating (3.0 A @ TT = 75°C), thermal resistance (25 K/W), fast recovery performance (150 ns), and SMB package compatibility with automated SMT assembly.

Technical Context

This device implements a glass-passivated silicon PN junction optimized for high-efficiency, medium-power rectification in single-phase, half-wave configurations. Its fast recovery time (150 ns) minimizes switching losses during turn-off, while low forward voltage (1.3 V @ 3.0 A) reduces conduction loss under continuous load.

The SMB package provides validated thermal performance (R_JT = 25 K/W with 5.0 mm² copper pad) and meets UL 94V-0 flammability requirements. Polarity is marked by cathode band; terminals are solder-plated per MIL-STD-202, Method 208.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - maximum peak repetitive reverse voltage; defines safe blocking capability in AC line rectification.
I_O	3.0 A @ T_T = 75°C - average rectified current rating; determines continuous power handling in half-wave resistive/inductive loads.
V_FM	1.3 V @ I_F = 3.0 A - forward voltage drop; directly impacts conduction loss and thermal design in high-duty-cycle operation.
t_rr	150 ns - reverse recovery time; critical for minimizing switching loss and EMI in 50–100 kHz SMPS front-ends.
I_FSM	100 A - non-repetitive surge rating (8.3 ms half-sine); supports inrush current tolerance during cold-start conditions.
R_JT	25 K/W - junction-to-terminal thermal resistance; enables accurate thermal modeling when mounted on standard PCB copper pads.

Pinout & Package

SMB (DO-214AA) plastic package with molded body, solder-plated terminals, and cathode polarity indicated by a band on the case. Weight: 0.09 g. UL 94V-0 rated.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Input terminal for positive half-cycle conduction	Connected to AC source or transformer secondary; must withstand full reverse voltage when off.
Cathode	Output terminal for rectified DC current	Connected to bulk capacitor or downstream converter; carries full average output current and ripple.

Key Features

Feature	Design Value
Glass-passivated die	Enhances long-term reliability and moisture resistance in humid or thermally cycled environments.
Fast recovery (150 ns)	Reduces reverse recovery charge (Q_rr) and associated switching losses in high-frequency converters.
Low V_F (1.3 V @ 3 A)	Lowers conduction loss by ~15% vs. standard recovery rectifiers, improving efficiency in 12–24 V output supplies.
100 A surge rating	Withstands repeated cold-start surges without degradation, eliminating need for external NTC inrush limiters.

Use Scenario: Input rectification in 100–500 W industrial switch-mode power supplies with wide-input ranges.

IC Role / Device Role / Timing Role: Half-wave rectifier in bridgeless or conventional diode bridge configurations.

Use Value: 3.0 A I_O rating supports continuous operation at 75°C ambient; 25 K/W R_JT enables stable thermal performance on standard PCB layouts.

LED Driver Bulk Rectification

UPS Charger Input Stage

Use Scenario: Converting AC line to DC bus for constant-current LED drivers in commercial lighting.

IC Role / Device Role / Timing Role: Main rectifier feeding bulk capacitor; operates in discontinuous conduction mode.

Use Value: Low 1.3 V V_FM reduces heat generation in enclosed fixtures; UL 94V-0 package meets safety compliance requirements.

Use Value: 100 A I_FSM accommodates repeated battery reconnection surges; cathode-band marking ensures correct polarity during high-volume assembly.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L04S	Same 400 V V_RRM, 3.0 A I_O, but 120 ns t_rr and 1.25 V V_FM; SMB package.	Slightly lower conduction loss and faster recovery; preferred where <100 ns t_rr is required for EMI reduction.	Select STTH3L04S if optimizing for lowest possible Q_rr in high-frequency designs; verify layout parasitics support faster edge rates.
ES3G	Same 400 V V_RRM, 3.0 A I_O, but 250 ns t_rr and 1.35 V V_FM; SMB package.	Slower recovery increases switching loss in >50 kHz topologies; higher V_F raises thermal load at full load.	Select ES3G only for cost-sensitive, low-frequency (<30 kHz) applications where thermal margin is ample and EMI is not critical.

Compared with RS3GB-13-F, STTH3L04S offers superior dynamic performance at marginally higher cost, while ES3G trades speed and efficiency for lower unit price - making RS3GB-13-F the balanced choice for mainstream 50–100 kHz AC/DC converters requiring proven reliability and thermal stability.

FAQ

What is the maximum operating junction temperature for RS3GB-13-F?

The RS3GB-13-F has an operating junction temperature range of –65°C to +150°C. Its rated average output current (3.0 A) is specified at terminal temperature (T_T) = 75°C, and derating follows the curve in Figure 1 - full current is usable up to T_T = 75°C, decreasing linearly to zero at ~150°C terminal temperature.

Can RS3GB-13-F be used in full-wave bridge configurations?

Yes, RS3GB-13-F is commonly used as one leg in discrete full-wave bridge rectifiers. Each device handles half the AC cycle, so four units form a complete bridge. Its 400 V V_RRM supports 230 V AC RMS inputs with adequate safety margin, and its SMB footprint allows dense, automated placement.

Is RS3GB-13-F compliant with lead-free and RoHS requirements?

Yes, RS3GB-13-F is lead-free and RoHS-compliant. The device uses lead-free solder plating on terminals and conforms to JEDEC J-STD-020 moisture sensitivity level (MSL) 1 - unlimited floor life at ≤30°C/85% RH - and is compatible with standard Pb-free reflow profiles.

How does the 150 ns recovery time affect EMI in a 65 kHz flyback converter?

A 150 ns t_rr results in moderate reverse recovery charge (Q_rr ≈ 35 nC), which contributes to high-frequency ringing during turn-off. In a 65 kHz flyback, this can elevate conducted EMI above 30 MHz; adding a small RC snubber across the device or using soft-recovery variants may be necessary for Class B compliance.
