Product details
Overview
FR1K-13 from Diodes Incorporated is a glass passivated fast recovery rectifier diode rated for 800 V maximum recurrent peak reverse voltage (VRRM), 1.0 A average forward current at 75°C (I(AV)), and 150 ns reverse recovery time (trr), designed for high-efficiency AC/DC input stage rectification in compact surface-mount power supplies.
For engineers reviewing the FR1K-13 datasheet, FR1K-13 pinout, FR1K-13 application, or FR1K-13 equivalent, key selection considerations include its SMB package thermal resistance (30 °C/W junction-to-lead), 1.3 V forward voltage at 1.0 A, 5.0 µA max DC reverse current at 25°C, and suitability for 60 Hz half-wave rectification with surge capability up to 30 A (8.3 ms).
Technical Context
This device operates as a unidirectional silicon PN junction rectifier with glass passivation for enhanced reliability and moisture resistance. Its fast recovery (trr = 150 ns) enables reduced switching losses in medium-frequency line rectification, while the SMB surface-mount package supports automated assembly and thermal dissipation via 6.0 mm² copper pads.
It is specified for single-phase, half-wave resistive or inductive loads at 60 Hz, with derating required above 75°C ambient. The cathode band polarity marking and UL 94V-0 flammability rating confirm compliance for industrial and consumer-grade surface-mounted applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum sustainable reverse voltage before breakdown; defines safe operating margin in 600–700 VAC input designs. |
| I(AV) | 1.0 A @ TA = 75°C - Continuous DC output current capability under standard heatsinking; requires derating above 75°C ambient. |
| trr | 150 ns - Measured at IF = 0.5 A, IR = 1 A, IRR = 0.25 A; enables efficient operation up to ~100 kHz switching frequencies in PFC front-ends. |
| VF | 1.3 V @ 1.0 A - Forward conduction loss directly impacts conduction efficiency and thermal rise in rectifier stage. |
| IR | 5.0 µA @ 25°C, 800 V - Low leakage ensures minimal standby power loss and stable blocking in high-impedance circuits. |
| RθJL | 30 °C/W - Thermal resistance from junction to lead with 6.0 mm² copper pad; determines temperature rise under 1.0 A load. |
| CJ | 15 pF @ 4.0 V, 1.0 MHz - Junction capacitance affects high-frequency noise coupling and EMI filter design. |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case with glass passivated junction, cathode band marking, UL 94V-0 rated, weight ≈ 0.093 g.
| 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 | Marked by band; connects to bulk capacitor or downstream converter; carries full average forward current. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | 150 ns - Reduces reverse recovery charge (Qrr) and associated switching losses in line-frequency rectifiers. |
| Glass passivated junction | Enhanced environmental robustness - Resists moisture ingress and improves long-term reliability in humid or submersible conditions. |
| SMB surface-mount package | Compact footprint (3.3–3.94 mm × 4.0–4.65 mm) - Enables high-density PCB layouts and compatibility with standard reflow profiles. |
| High surge rating | 30 A non-repetitive peak (8.3 ms half-sine) - Withstands inrush currents during cold-start of power supplies without failure. |
Applications
| AC/DC Adapter Input Stage | Industrial Control Power Supply |
|---|---|
Use Scenario: Rectifying 230 VAC mains input in compact wall-wart adapters with space-constrained PCBs. IC Role / Device Role / Timing Role: Primary-side unidirectional current path; blocks reverse voltage during negative half-cycles and conducts during positive half-cycles. Use Value: 800 V VRRM provides 2× safety margin over 230 VAC RMS, while 150 ns trr minimizes switching loss and audible noise in low-cost flyback topologies. | Use Scenario: Providing isolated DC bias for PLC I/O modules operating in factory environments with variable line quality. IC Role / Device Role / Timing Role: Input rectifier in transformer-isolated auxiliary supply; handles repetitive surges and wide ambient temperature swings. Use Value: -65°C to +175°C operating range and UL 94V-0 housing ensure functional stability across industrial temperature extremes and fire-safety compliance. |
| LED Driver Bulk Rectification | Appliance Motor Control Board |
Use Scenario: Converting 120/230 VAC to DC bus for constant-current LED drivers in commercial lighting fixtures. IC Role / Device Role / Timing Role: High-voltage, low-leakage rectifier feeding bulk capacitor; must maintain low IR to minimize no-load power consumption. Use Value: 5.0 µA max IR at 25°C and 800 V reduces standby power loss, supporting Energy Star and ERP Tier 2 efficiency requirements. | Use Scenario: Rectifying AC from triac-controlled motor windings in washing machine or HVAC blower control boards. IC Role / Device Role / Timing Role: Freewheeling and input rectification element exposed to inductive kickback and line transients. Use Value: 30 A surge rating and glass passivation protect against repetitive voltage spikes and humidity-induced degradation in sealed appliance enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RS1KB-13 | Same SMB package, 800 V VRRM, but trr = 250 ns; VF = 1.3 V same; lower IR (1.0 µA @ 25°C) | Higher reliability in low-leakage critical designs; slightly slower recovery increases switching loss marginally | Preferred where ultra-low standby leakage dominates over switching speed |
| ES1J-E3/54 | Same 600 V VRRM rating not applicable; ES1J is 600 V - insufficient for 800 V requirement; trr = 35 ns, VF = 1.7 V | Not suitable as direct replacement due to lower VRRM; only viable in 277 VAC or lower systems | Select only if system peak reverse voltage remains ≤600 V and faster recovery justifies higher VF penalty |
Compared with FR1K-13, RS1KB-13 offers tighter leakage control but sacrifices 100 ns in recovery speed, whereas ES1J-E3/54 fails the 800 V blocking requirement entirely-making FR1K-13 the only validated option for 700–800 V peak line applications requiring SMB footprint and 150 ns trr.

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design and manufacturing operations across Asia and the Americas.
The FR1A–FR1M series was developed specifically for cost-sensitive, high-volume surface-mount rectification in consumer and industrial power supplies where reliability, thermal performance, and standardized SMB packaging are essential.
FAQ
Is FR1K-13 suitable for use in 230 VAC input applications?
Yes. With a 800 V VRRM rating, FR1K-13 provides a 2.4× safety margin over the 325 V peak of 230 VAC, satisfying IEC/UL creepage and surge withstand requirements for Class II power supplies. Its 150 ns trr and 1.3 V VF further support efficient operation in universal-input designs.
What is the maximum PCB copper area needed to achieve the 30 °C/W RθJL specification?
The 30 °C/W thermal resistance is measured with 6.0 mm² of 1 oz copper pad per lead, per Diodes Incorporated DS15003 Rev. 5. Using less copper increases thermal resistance linearly; doubling pad area to 12 mm² typically improves RθJL by ~20%, but layout must maintain symmetry and avoid solder mask over thermal pads.
Does FR1K-13 have lead-free and RoHS-compliant construction?
Yes. FR1K-13 is manufactured with lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH SVHC regulations. The SMB package uses halogen-free molding compound and meets JEDEC J-STD-020 moisture sensitivity level MSL3, qualifying it for standard reflow soldering processes.
Why does the datasheet state "NOT RECOMMENDED FOR NEW DESIGNS"?
This note refers to the entire FR1A–FR1M family being superseded by the RS1A–RS1M series, which offer improved trr consistency, tighter VF distribution, and enhanced surge robustness. However, FR1K-13 remains fully qualified, in active production, and supported for legacy design refreshes and cost-driven replacements where RS1KB-13 is not yet approved.
