Product details
Overview
FR154GH from Taiwan Semiconductor is a 1.5A, 400V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and 50 A surge current capability-designed for high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the FR154GH datasheet, FR154GH pinout, FR154GH application, or FR154GH equivalent, key selection criteria include its AEC-Q101 qualification, glass-passivated junction, 150 ns trr, 5 µA max IR at 25°C, and DO-15 mechanical compatibility with standard through-hole power rectifier footprints.
Technical Context
This single-die, unidirectional fast recovery rectifier uses a glass-passivated PN junction to achieve low forward voltage and stable high-temperature reverse leakage. Its 150 ns reverse recovery time enables operation in medium-frequency switching topologies up to ~100 kHz without excessive switching loss.
The device operates across -55°C to +150°C junction temperature range, with 60°C/W junction-to-ambient thermal resistance and pure tin-plated leads compliant with J-STD-002 solderability. Polarity is marked by a cathode band on the DO-15 body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage before breakdown; sets usable DC bus or output voltage ceiling in flyback/forward converters. |
| IF | 1.5 A continuous - Average forward current rating at TA = 75°C; defines steady-state conduction capability in power supply outputs. |
| IFSM | 50 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush handling during startup or fault transients. |
| trr | 150 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient operation in 50–100 kHz SMPS without excessive diode switching loss. |
| VF (max) | 1.3 V at IF = 1.5 A, TJ = 25°C - Directly determines conduction loss (Pcond ≈ VF × IF); impacts thermal design and efficiency at full load. |
| IR (max) | 5 µA at VR = 400 V, TJ = 25°C - Low leakage preserves regulation in high-impedance feedback paths and reduces standby power loss. |
| TJ max | +150°C - Enables reliable operation in enclosed industrial or automotive under-hood environments without derating below 100°C ambient. |
Pinout & Package
Package: DO-204AC (DO-15), axial lead, glass-passivated single-die rectifier. Cathode indicated by molded band. Leads are pure tin-plated, J-STD-002 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node return path) in bridge or half-wave configurations. |
| Cathode (Lead 2) | Forward current exit / reverse blocking terminal | Connected to output rail or positive bus; cathode band identifies polarity for correct PCB orientation and avoids reverse bias failure. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics including engine control modules and body electronics where reliability under thermal cycling and vibration is critical. |
| Glass passivated junction | Provides hermetic protection against moisture and contaminants, improving long-term stability of VF and IR over 15+ year service life. |
| Low VF (≤1.3 V) | Reduces conduction loss by ≥15% vs. standard recovery diodes at 1.5 A, lowering heatsink requirements in space-constrained adapters. |
| 150 ns trr | Minimizes reverse recovery charge (Qrr), reducing EMI generation and MOSFET turn-on loss in synchronous rectified topologies. |
| RoHS & halogen-free | Complies with IEC 61249-2-21; suitable for consumer, industrial, and automotive assemblies requiring green manufacturing compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 1 A, 600 V, 75 ns trr, SOD-123FL package - lower current, faster recovery, surface-mount only | Not suitable for 1.5 A continuous loads; requires PCB redesign for SMT footprint and thermal pad layout | Select when board space is constrained and peak current stays ≤1 A; not a drop-in replacement for FR154GH. |
| ON Semi MUR1540G | 1.5 A, 400 V, 75 ns trr, DO-15 package - same VRRM/IF, faster trr, non-AEC-Q101 | Lacks automotive qualification; higher cost per unit but superior switching performance in noise-sensitive SMPS | Prefer for industrial SMPS where ultra-low EMI is prioritized over automotive compliance; identical DO-15 footprint allows direct substitution if AEC-Q101 not required. |
Compared with STTH1L06S and MUR1540G, FR154GH uniquely balances AEC-Q101 qualification, 1.5 A capability, and DO-15 through-hole compatibility-making it optimal for automotive and industrial designs needing proven reliability without SMT retooling.

FAQ
What is the maximum junction temperature rating for FR154GH?
The FR154GH has a maximum junction temperature (TJ max) of +150°C, verified per JEDEC JESD22-A108. This rating allows continuous operation in high-ambient environments such as engine compartments or sealed industrial enclosures. Derating begins above 75°C ambient, per the forward current derating curve in the FR151G–FR157G datasheet Version I2105.
Is FR154GH pin-compatible with other DO-15 fast recovery diodes like FR154G?
Yes, FR154GH shares identical DO-204AC (DO-15) mechanical dimensions, lead spacing, and polarity marking (cathode band) with FR154G. The "H" suffix denotes AEC-Q101 qualification but does not alter package or pinout-making FR154GH a direct physical replacement where automotive-grade reliability is required.
What is the reverse recovery time (trr) specification for FR154GH, and under what test conditions?
The FR154GH has a maximum reverse recovery time (trr) of 150 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per JEDEC JESD282B. This value is confirmed in the Electrical Specifications table of the FR151G–FR157G datasheet (Version I2105, Page 2).
Does FR154GH meet RoHS and halogen-free requirements?
Yes, FR154GH is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. This is explicitly stated in the FEATURES section of the official Taiwan Semiconductor datasheet.
What is the surge current rating (IFSM) for FR154GH, and how is it defined?
The FR154GH has a non-repetitive peak forward surge current (IFSM) rating of 50 A, defined per JEDEC JESD22-A112 as a single 8.3 ms half-sine wave applied at TA = 25°C. This rating supports transient overload events such as input power-up surges or motor startup currents without junction failure.
