Product details
Overview
FR106GH from Taiwan Semiconductor is a 1A, 800V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 500 ns reverse recovery time, 1.3 V forward voltage at 1 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the FR106GH datasheet, FR106GH pinout, FR106GH application, or FR106GH equivalent, key selection criteria include peak reverse voltage (800 V), surge current capability (30 A), thermal resistance (70 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for automotive power conversion designs.
Technical Context
This device operates as a single-die, unidirectional fast recovery rectifier with glass-passivated junction for enhanced moisture resistance and long-term stability under thermal cycling. Its 500 ns trr enables efficient operation in high-frequency switching topologies up to several hundred kHz.
The FR106GH supports continuous forward current of 1 A at 75 °C ambient (derated from 150 °C max junction temperature), with low leakage (≤100 µA at 125 °C) and junction capacitance of 10 pF at 4 V reverse bias - critical for minimizing switching losses and EMI in DC/DC stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - blocks up to 800 V repetitive reverse voltage without breakdown, suitable for 400 V DC bus systems with safety margin |
| IF | 1 A continuous - delivers rated output current in compact DO-41 footprint without forced cooling |
| trr | 500 ns - enables use in 100–300 kHz SMPS designs where slower diodes cause excessive switching loss |
| VF | 1.3 V max at 1 A, 25 °C - limits conduction loss to ≤1.3 W per diode in linear-regulated or freewheeling paths |
| IFSM | 30 A peak (8.3 ms half-sine) - withstands inrush and transient surges common in offline AC-DC front-ends |
| RθJA | 70 °C/W - requires minimal PCB copper area for thermal management in space-constrained automotive modules |
| AEC-Q101 | Qualified - validated for automotive applications including engine control units and body electronics |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, glass-passivated silicon die, cathode indicated by band. Weight: 0.340 g. Leads are pure tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Current entry point during forward conduction | Connected to lower-potential node (e.g., switch node in buck freewheel path or transformer secondary center-tap) |
| Cathode (banded end) | Current exit point during forward conduction; blocking terminal during reverse bias | Connected to output rail or positive bus; must sustain full VRRM when reverse-biased in flyback or boost configurations |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood environments including temperature cycling, humidity bias, and mechanical shock |
| Glass passivated junction | Prevents moisture ingress and metallization corrosion, extending lifetime in humid or condensing conditions |
| Low VF (1.3 V max) | Reduces power dissipation by ~15% vs. standard recovery diodes at 1 A, lowering heatsink requirements |
| High IFSM (30 A) | Survives cold-start surges and capacitor charging transients without degradation in industrial power supplies |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU directives for environmentally constrained automotive and consumer manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R08 | Same 1 A / 800 V rating; trr = 500 ns; TO-220AC package (larger, higher RθJA) | Requires heatsink for >0.5 A continuous; unsuitable for space-constrained DO-41 layouts | Select when higher surge robustness and thermal mass are prioritized over board space |
| ON Semiconductor MUR108 | 1 A / 800 V; trr = 50 ns (faster); DO-41; no AEC-Q101 qualification | Lacks automotive qualification; not recommended for under-hood deployment | Select for cost-sensitive industrial SMPS where AEC-Q101 is not required and faster recovery is beneficial |
Compared with STTH1R08 and MUR108, the FR106GH uniquely combines AEC-Q101 qualification, DO-41 form factor, and 500 ns trr - making it the only drop-in solution for automotive-grade, space-limited 800 V rectification without layout or qualification compromise.

What is the peak repetitive reverse voltage rating of the FR106GH?
The FR106GH has a peak repetitive reverse voltage (VRRM) rating of 800 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2104). It defines the maximum reverse voltage the FR106GH can block repeatedly without breakdown under normal operating conditions, making it suitable for applications with up to 400 V DC bus systems plus safety margin.
Is the FR106GH qualified for automotive applications?
Yes, the FR106GH is AEC-Q101 qualified, as confirmed by the "H" suffix in its ordering code and explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification validates the FR106GH for use in automotive electronic control units, body electronics, and other under-hood or cabin applications subject to rigorous stress testing including temperature cycling, humidity bias, and mechanical shock.
What is the reverse recovery time (trr) of the FR106GH, and how is it measured?
The FR106GH has a reverse recovery time (trr) of 500 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in the ELECTRICAL SPECIFICATIONS table. This parameter reflects the time required for the FR106GH to transition from forward conduction to reverse blocking state, directly impacting switching losses in high-frequency power converters.
Does the FR106GH have RoHS and halogen-free compliance?
Yes, the FR106GH is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability rating, and the leads are pure tin-plated - all confirming environmental compliance required for automotive and consumer electronics manufacturing.
What package type does the FR106GH use, and what are its mechanical characteristics?
The FR106GH uses the DO-204AL (DO-41) axial-leaded package. Mechanical features include glass passivation for junction protection, pure tin-plated leads solderable per J-STD-002, polarity indicated by cathode band, and a weight of approximately 0.340 g. The package meets JESD 201 Class 2 whisker test requirements, ensuring long-term interconnect reliability.
