Product details
Overview
FRS1JE from Diodes Incorporated is a surface-mount fast recovery rectifier diode rated for 600 V repetitive peak reverse voltage and 1.0 A average forward current at TC = 125°C, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 1.0 A, and qualified to AEC-Q101 Rev_C for automotive under-hood power conversion.
For engineers reviewing the FRS1JE datasheet, FRS1JE pinout, FRS1JE application, or FRS1JE equivalent, key selection criteria include its DO-219AA (F1A) package thermal resistance (RthJC = 20 °C/W), low leakage (≤5 µA at 600 V, TJ = 100°C), and suitability for high-frequency flyback and boost converters requiring fast switching and RoHS-compliant green packaging.
Technical Context
This device operates as a unidirectional power rectifier in AC/DC and DC/DC stages, with junction temperature range from –55°C to +150°C and thermal resistance from junction-to-case of 20 °C/W. Its 7 pF typical junction capacitance at 4 V reverse bias supports high-frequency operation up to several hundred kHz.
The fast recovery characteristic (trr ≤ 250 ns) is achieved via optimized lifetime control in the epitaxial silicon structure, enabling reduced switching losses compared to standard recovery diodes-critical in 65–300 kHz SMPS topologies where diode conduction loss and reverse recovery loss dominate efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive 600 V reverse transients without breakdown in bridge or flyback snubber circuits. |
| I(AV) | 1.0 A @ TC = 125°C - Sustains continuous 1 A output in compact heatsink-limited designs such as USB-C PD adapters. |
| trr | 250 ns - Enables efficient operation in 200+ kHz switching converters by minimizing reverse recovery charge (Qrr) and associated turn-off losses. |
| VF | 1.3 V max @ IF = 1.0 A, TJ = 25°C - Limits conduction loss to ≤1.3 W at full load, supporting thermally constrained PCB layouts. |
| RthJC | 20 °C/W - Allows direct thermal path to copper pad, enabling >0.8 A derated current at TJ = 125°C with minimal external heatsinking. |
| IR | 5 µA max @ VR = 600 V, TJ = 100°C - Ensures low standby power loss in high-voltage hold-up and auxiliary supply rails. |
| CT | 7 pF @ 4 V, 1 MHz - Minimizes capacitive coupling noise and EMI generation in high-dV/dt gate-drive or feedback paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR160 | Same 600 V VRRM, 1 A I(AV), but TO-220AC package (RthJC = 50 °C/W); trr = 50 ns (faster), VF = 1.25 V max. | Requires through-hole mounting and heatsink; unsuitable for ultra-thin or high-density SMT designs. | Select when lowest possible trr is critical and board space/height constraints allow TO-220 footprint. |
| Vishay VS-1EWH06-M3 | DO-219AB (same outline), 600 V, 1 A, trr = 250 ns, VF = 1.35 V max, RthJC = 22 °C/W; AEC-Q101 qualified. | Nearly identical thermal and electrical specs; differs only in minor VF tolerance and JEDEC registration. | Drop-in replacement with identical layout and thermal management; preferred for dual-sourcing in automotive programs. |
Compared with MUR160 and VS-1EWH06-M3, FRS1JE offers the best balance of AEC-Q101 compliance, ultra-low profile (1.18 mm height), and industry-leading RthJC (20 °C/W) for thermally aggressive SMT applications-making it optimal for space-constrained automotive and industrial power modules.

FAQ
What is the maximum allowable case temperature for continuous operation of FRS1JE?
The FRS1JE is rated for 1.0 A average forward current at TC = 125°C, with absolute maximum junction temperature of +150°C. Its RthJC = 20 °C/W allows sustained operation at TC = 125°C when mounted on a 5 × 7 mm copper pad per JESD-51 standards. Derating curves confirm usable current down to 0.6 A at TC = 150°C.
Does FRS1JE support reflow soldering per IPC-J-STD-020?
Yes-FRS1JE's DO-219AA package and matte tin plating are fully compatible with lead-free reflow profiles per IPC-J-STD-020D, including peak temperatures up to 260°C for ≤30 seconds. The "green" molding compound meets UL 94V-0 flammability and withstands thermal shock across –55°C to +150°C cycles without delamination.
How does the 250 ns reverse recovery time impact EMI in high-frequency converters?
At 250 ns trr, FRS1JE limits reverse recovery di/dt and associated high-frequency ringing, reducing common-mode EMI above 30 MHz by up to 8 dB compared to 1 µs recovery diodes. This enables simpler EMI filter design in 200–500 kHz flyback and LLC converters without sacrificing efficiency.
Is FRS1JE pin-compatible with other DO-219AA rectifiers like VS-1EWH06-M3?
Yes-FRS1JE uses the standardized DO-219AA (F1A) footprint with identical 3.8 mm × 1.9 mm outline and anode/cathode terminal locations. Mechanical drawings confirm matching pad dimensions, solder mask openings, and thermal pad requirements, enabling direct PCB layout reuse across qualified alternatives.
