Product details
Overview
FR1G-13 from Diodes Incorporated is a glass passivated fast recovery rectifier diode in SMB package, rated for 400 V maximum recurrent peak reverse voltage (VRRM), 1.0 A average forward rectified current at 75°C (I(AV)), and 150 ns reverse recovery time (trr); used in AC/DC input stage flyback snubber networks and offline switch-mode power supply output rectification.
For engineers reviewing the FR1G-13 datasheet, FR1G-13 pinout, FR1G-13 application, or FR1G-13 equivalent, key selection criteria include VRRM margin for 230 VAC mains surge tolerance, trr < 200 ns for reduced switching loss in 65–130 kHz SMPS, VF ≤ 1.3 V at 1.0 A for thermal management, and SMB footprint compatibility with automated SMT assembly.
Technical Context
This device operates as a unidirectional surface-mount rectifier with glass-passivated PN junction, optimized for high-speed recovery in low-to-medium frequency switching converters. Its 150 ns trr (measured at IF = 0.5 A, IR = 1 A, IRR = 0.25 A) enables efficient operation up to ~100 kHz without significant commutation loss.
Thermal performance is defined by 30 °C/W junction-to-lead thermal resistance (RJL) under standard 6.0 mm² copper pad layout, supporting 1.0 A continuous conduction at TA = 75°C. Junction capacitance is 15 pF at 4.0 V reverse bias and 1.0 MHz, minimizing high-frequency coupling in snubber circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands peak line voltage + surge transients in 230 VAC-input SMPS without avalanche breakdown. |
| I(AV) | 1.0 A @ TA = 75°C - Supports continuous output rectification up to ~12 W in compact open-frame adapters. |
| trr | 150 ns - Enables low-loss commutation in flyback and forward converters operating below 100 kHz. |
| VF | 1.3 V @ IF = 1.0 A - Limits conduction loss to ≤1.3 W per diode, easing thermal design on 1-oz copper PCBs. |
| CJ | 15 pF @ VR = 4.0 V, 1.0 MHz - Reduces EMI generation in high-dv/dt switching nodes compared to slower rectifiers. |
| RJL | 30 °C/W - Requires ≥6.0 mm² copper pad for safe 1.0 A operation at 75°C ambient without derating. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-banded polarity, UL 94V-0 molded plastic case, weight 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry node | Connected to transformer secondary or switching node; must withstand peak inverse voltage during off-state. |
| Cathode | Forward current exit node | Connected to output capacitor or load return; marked by molded band; carries full DC output current. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | 150 ns trr ensures minimal reverse recovery charge (Qrr) and reduced switching loss in 65–100 kHz converters. |
| Glass passivated junction | Enhances humidity resistance and long-term reliability in industrial environments per MIL-STD-19500. |
| SMB package | Standardized footprint compatible with JEDEC MS-012AC, enabling drop-in replacement and high-yield reflow soldering. |
| High surge rating | 30 A IFSM (8.3 ms half-sine) supports inrush current handling during cold-start of AC/DC supplies. |
Applications
| AC/DC Adapter Output Rectification | Flyback Snubber Clamp Diode |
|---|---|
Use Scenario: 5–12 W universal-input wall adapter with single-output flyback topology. IC Role / Device Role / Timing Role: Output rectifier conducting during transformer reset phase; handles continuous 0.8–1.0 A DC output current. Use Value: 1.3 V VF minimizes conduction loss; 400 V VRRM provides 2× margin over reflected 170 V peak voltage. | Use Scenario: Clamp network in 24 V/1 A offline flyback converter protecting primary-side MOSFET. IC Role / Device Role / Timing Role: Fast-recovery clamp diode conducting only during transformer leakage energy dissipation (sub-µs duration). Use Value: 150 ns trr limits voltage overshoot; SMB package allows tight layout near transformer and RCD network. |
| Industrial Control Power Supply Input Stage | LED Driver Secondary-Side Rectification |
Use Scenario: 24 V/0.5 A auxiliary power rail derived from main 400 V DC bus in PLC power module. IC Role / Device Role / Timing Role: Half-wave rectifier feeding linear regulator or buck controller; operates continuously at 75°C ambient. Use Value: 30 °C/W RJL enables stable operation with minimal copper area; UL 94V-0 housing meets industrial safety standards. | Use Scenario: Constant-current LED driver with isolated flyback stage powering 12 V/350 mA string. IC Role / Device Role / Timing Role: Secondary-side synchronous rectification alternative where cost-sensitive design favors simple diode solution. Use Value: 15 pF CJ reduces high-frequency noise coupling into LED current sense path; 1.0 A I(AV) supports 350 mA with >2× margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RS1G-13 | VRRM = 400 V, trr = 150 ns, VF = 1.3 V - identical ratings but uses planar epitaxial process instead of glass passivation. | No difference in circuit function; RS1G-13 has slightly lower leakage at 125°C (IR = 5 µA vs. FR1G-13's 5 µA at 25°C, 100 µA at 125°C). | Select RS1G-13 if long-term humidity exposure is not expected and lower cost is prioritized. |
| ES1D-E3/57T | VRRM = 200 V, trr = 35 ns, VF = 0.95 V - lower voltage rating but faster recovery and lower forward drop. | Not suitable for 230 VAC-derived 400 V bus; appropriate only for 115 VAC-input or low-voltage DC-DC secondaries. | Choose ES1D-E3/57T only when system peak reverse voltage is ≤200 V and sub-50 ns trr is required for >200 kHz operation. |
Compared with RS1G-13, FR1G-13 offers superior moisture resistance due to glass passivation, critical for outdoor or high-humidity industrial deployments; versus ES1D-E3/57T, it trades speed for higher voltage capability-making FR1G-13 the preferred choice for universal-input offline SMPS where 400 V standoff is mandatory.

FAQ
What is the maximum allowable junction temperature for FR1G-13?
The absolute maximum junction temperature (TJ) is +175°C, with continuous operation limited to TJ ≤ 150°C for reliable long-term performance. Derating begins at TA = 75°C per Figure 1 in DS15003 Rev. 5–3, where I(AV) drops linearly to zero at TA = 150°C.
Can FR1G-13 replace FR1J-13 in a 600 V design?
No - FR1G-13 has VRRM = 400 V, while FR1J-13 is rated for 600 V. Substituting FR1G-13 in a 600 V application risks avalanche breakdown during line surges or transient spikes, especially in 230 VAC systems with poor input filtering.
Is FR1G-13 lead-free and RoHS compliant?
Yes - FR1G-13 meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations per J-STD-609. The SMB package uses matte tin plating over copper leads, qualified for Pb-free reflow soldering up to 265°C for 10 seconds.
Does FR1G-13 support automated optical inspection (AOI) after reflow?
Yes - the SMB package's well-defined cathode band, consistent mold compound contrast, and coplanar lead geometry enable reliable AOI detection. Diodes Incorporated specifies ±0.1 mm band position tolerance and 0.15–0.40 mm lead thickness (D dimension), supporting standard AOI algorithms.
