Product details
Overview
FR151GHR0G from Taiwan Semiconductor is a 1.5A, 50V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 1.3V max forward voltage at 1.5A, 50A surge capability, 150ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as the primary output rectifier in low-voltage DC-DC converters.
For engineers reviewing the FR151GHR0G datasheet, FR151GHR0G pinout, FR151GHR0G application, or FR151GHR0G equivalent, key selection criteria include its 50V VRRM, 150ns trr, glass-passivated junction, RoHS/halogen-free compliance, and DO-15 mechanical compatibility with legacy through-hole power designs.
Technical Context
This single-die, unidirectional fast recovery rectifier uses a glass-passivated PN junction to achieve low conduction loss and rapid carrier recombination. Its 150ns reverse recovery time enables efficient operation in 50–200 kHz switching converters without excessive switching loss or EMI generation.
The device operates across –55°C to +150°C junction temperature range, with 60°C/W junction-to-ambient thermal resistance and 5µA max reverse leakage at 25°C - supporting stable performance in thermally constrained industrial and automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in 12–24V DC-DC output stages. |
| IF | 1.5 A continuous - Rated average forward current; supports sustained load delivery in compact power supplies. |
| IFSM | 50 A (8.3 ms half-sine) - Peak non-repetitive surge rating; handles cold-start inrush and transient overloads. |
| trr | 150 ns - Measured at IF=0.5A, IR=1.0A, Irr=0.25A; enables high-frequency switching with minimal turn-off loss. |
| VF | 1.3 V max at IF=1.5A, TJ=25°C - Low forward drop reduces conduction loss and improves efficiency in low-VOUT designs. |
| TJ max | +150°C - Maximum junction temperature; allows operation in sealed enclosures or near heat-generating components. |
| CJ | 20 pF at 1 MHz, VR=4V - Junction capacitance impacts high-frequency noise coupling and snubber design in flyback topologies. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, glass-passivated, RoHS/halogen-free molded case with cathode band polarity marking. Weight: ~0.400 g.

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 MUR150 | Same 1.5A/50V rating, but TO-220AC package (surface-mount compatible); 100ns trr, higher thermal mass. | Requires PCB layout change; better suited for forced-air-cooled industrial PSUs than space-limited consumer adapters. | Select when board space permits larger footprint and lower trr is critical for >300 kHz operation. |
| Vishay VS-1N4933GP-E3/54 | DO-15 package, 1.5A/50V, but standard recovery (2 µs trr); no AEC-Q101 qualification; 1.1V VF typ. | Acceptable for <50 kHz linear or quasi-resonant supplies; unsuitable for automotive or high-efficiency SMPS. | Choose only for cost-driven, low-frequency applications where fast recovery is not required. |
Compared with MUR150 and VS-1N4933GP-E3/54, FR151GHR0G uniquely combines DO-15 through-hole compatibility, 150ns trr, AEC-Q101 qualification, and halogen-free construction - making it optimal for automotive-qualified, space-constrained, medium-frequency power conversion where pinout retention and reliability are mandatory.

FAQ
What is the maximum junction temperature rating for FR151GHR0G?
The FR151GHR0G has a maximum junction temperature (TJ) of +150°C, verified per JEDEC JESD22-A103. This rating allows reliable operation in enclosed automotive and industrial environments where ambient temperatures exceed 85°C. The FR151GHR0G maintains specified electrical parameters up to this limit, provided thermal design meets the 60°C/W RθJA derating curve.
Is FR151GHR0G pin-compatible with standard DO-15 rectifiers like 1N4007?
Yes, FR151GHR0G uses the DO-204AC (DO-15) package with identical lead spacing, diameter, and cathode band polarity marking as 1N4007 and 1N4933. It is a direct mechanical and soldering-process replacement - no PCB modification is required. However, its 150ns trr and 1.3V VF deliver superior performance in switching applications versus the 30 µs trr of 1N4007.
Does FR151GHR0G meet automotive qualification standards?
Yes, FR151GHR0G is AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. This certification covers stress tests including HTGB, HTRB, TCT, and mechanical shock, confirming suitability for automotive power electronics such as body control modules and infotainment power supplies. Full test reports are available upon request from Taiwan Semiconductor.
What is the reverse recovery time (trr) specification for FR151GHR0G?
The FR151GHR0G has a reverse recovery time (trr) of 150 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, and di/dt = 100 A/µs. This value is confirmed in the official Taiwan Semiconductor datasheet Version I2105 and enables efficient operation in 100–200 kHz switching converters without significant turn-off loss.
How does the glass passivation in FR151GHR0G improve reliability?
The glass passivation layer on the FR151GHR0G's silicon die provides superior environmental protection against moisture ingress, ionic contamination, and surface charge accumulation compared to organic passivants. This enhances long-term parameter stability and prevents premature failure in humid or condensing conditions - a key requirement for automotive and outdoor industrial deployments where the FR151GHR0G is commonly used.
