Product details

Overview

FR102GH from Taiwan Semiconductor is a 1A, 100V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 30 A surge current capability. It is AEC-Q101 qualified and used in automotive DC-DC converters and switching-mode power supplies.

For engineers reviewing the FR102GH datasheet, FR102GH pinout, FR102GH application, or FR102GH equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (70 °C/W), junction temperature range (−55 to +150 °C), RoHS/halogen-free compliance, and AEC-Q101 qualification status.

Technical Context

This device is a single-die, glass-passivated silicon PN junction rectifier optimized for fast switching in medium-power SMPS and automotive power conversion. Its 150 ns trr and low VF enable high-efficiency operation with reduced switching losses compared to standard recovery diodes.

The FR102GH operates across −55 °C to +150 °C junction temperature, supports 30 A non-repetitive surge current (8.3 ms half-sine), and exhibits only 5 µA max reverse leakage at 25 °C - critical for maintaining efficiency in standby and light-load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum repetitive reverse blocking voltage; defines safe operating limit in bridge or flyback clamp circuits
I_F	1 A continuous average forward current - sets steady-state power handling without heatsinking below 70 °C ambient
t_rr	150 ns - enables operation up to ~500 kHz switching frequency before reverse recovery losses dominate
V_F	≤1.3 V at I_F = 1 A, T_J = 25 °C - directly determines conduction loss (1.3 W dissipation at full load)
R_θJA	70 °C/W - allows ~14.3 °C rise per watt; limits usable power to ~0.7 W in free-air at 70 °C ambient
I_FSM	30 A (8.3 ms) - withstands inrush and fault currents in automotive cold-crank and load-dump scenarios
Junction Temp	−55 to +150 °C - meets under-hood automotive requirements and industrial extended-temperature operation

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06	Same 1 A / 600 V rating but higher V_RRM; t_rr = 75 ns, V_F = 1.15 V typ	Optimized for >200 kHz operation; not AEC-Q101 qualified	Preferred where higher speed and lower V_F outweigh automotive qualification needs
ON Semi MUR105E	1 A / 50 V, t_rr = 75 ns, V_F = 0.92 V typ; TO-220AC package	Higher thermal mass; requires PCB mounting; no AEC-Q101 or halogen-free certification	Used when board-level heat sinking is available and cost-per-watt is prioritized over qualification

Compared with STTH1R06 and MUR105E, the FR102GH trades speed and ultra-low V_F for AEC-Q101 compliance, DO-41 form factor, and halogen-free construction - making it uniquely suitable for space-constrained, automotive-qualified, and environmentally regulated designs.

FAQ

What is the peak repetitive reverse voltage rating of the FR102GH?

The FR102GH has a peak repetitive reverse voltage (V_RRM) rating of 100 V. This value is specified in the Absolute Maximum Ratings table and defines the maximum reverse-biased voltage the device can block continuously without breakdown. Exceeding this voltage risks avalanche failure or permanent degradation. The FR102GH is part of the FR101G–FR107G series, where the second digit indicates voltage grade: '02' = 100 V.

Is the FR102GH AEC-Q101 qualified, and what does that mean for design use?

Yes, the FR102GH is AEC-Q101 qualified - confirmed by the 'H' suffix in its ordering code and explicitly stated in the features list. This means the device has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge per the AEC-Q101 standard, validating its suitability for automotive electronic systems. The FR102GH is intended for under-hood and cabin applications where reliability under thermal, mechanical, and electrical stress is mandatory.

What is the reverse recovery time (t_rr) of the FR102GH, and how does it affect switching performance?

The FR102GH has a reverse recovery time (t_rr) of 150 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter directly impacts switching losses and EMI generation in high-frequency converters. A 150 ns t_rr enables efficient operation up to approximately 500 kHz before recovery-related losses dominate, making the FR102GH suitable for modern compact SMPS designs where faster recovery than standard rectifiers (e.g., 1N4007) is required.

Does the FR102GH have a specified junction-to-ambient thermal resistance, and how should it be used in thermal design?

Yes, the FR102GH has a junction-to-ambient thermal resistance (R_θJA) of 70 °C/W, measured in free-air conditions. This value is used to estimate junction temperature rise above ambient: T_J = T_A + (P_D × R_θJA). For example, at 1 A and 1.3 V forward drop (1.3 W dissipation), the junction rises ~91 °C above ambient - limiting usable ambient to ≤59 °C for safe operation at T_J ≤ 150 °C. PCB copper area or airflow improves actual R_θJA, but 70 °C/W is the baseline for worst-case layout analysis.

What packaging and marking information applies to the FR102GH?

The FR102GH is supplied in DO-204AL (DO-41) package with axial leads, pure tin plating, and UL 94V-0 molding compound. Marking consists of "FR102G" followed by date code (YWW) and factory code (F); the 'H' suffix appears only in the ordering code (e.g., FR102GH), not on the device body. Cathode polarity is indicated by a visible band. Tape-and-reel packaging contains 5,000 units per reel, while ammo box contains 3,000 units.
