Product details
Overview
RSFGLH from Taiwan Semiconductor is a fast recovery surface-mount rectifier diode with 400 V repetitive peak reverse voltage (VRRM), 0.5 A average forward current (IF), and 150 ns reverse recovery time (trr) under IF = 0.5 A / IR = 1.0 A test conditions, used in automotive DC-DC converters and snubber circuits.
For engineers reviewing the RSFGLH datasheet, RSFGLH pinout, RSFGLH application, or RSFGLH equivalent, key selection criteria include its Sub SMA package, AEC-Q101 qualification, 1.3 V max forward voltage at 0.5 A, 5 µA max reverse leakage at 25°C, and suitability for high-efficiency switching in constrained automotive and industrial power supplies.
Technical Context
The RSFGLH employs a glass-passivated single-die junction with metallurgically bonded construction for thermal robustness up to 150°C junction temperature. Its fast recovery behavior (trr = 150 ns) enables high-frequency operation in flyback and forward converter topologies.
Designed for automated SMT placement, the device features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is indicated by a cathode band on the Sub SMA case.
Key Specifications

|---|---|
| VRRM | 400 V - supports 400 V DC bus or 280 V RMS AC input in bridge configurations |
| IF | 0.5 A - continuous forward current rating suitable for low-power auxiliary rails |
| trr | 150 ns - enables efficient switching above 100 kHz without excessive switching loss |
| VF max | 1.3 V @ 0.5 A - limits conduction loss to ≤650 mW at rated current |
| IR max | 5 µA @ 25°C - ensures minimal leakage in high-impedance hold-up or sensing paths |
| RθJA | 150 °C/W - requires ≥25 mm² copper pad for safe operation at full IF in still air |

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 | VRRM = 600 V, trr = 110 ns, IF = 1.0 A, SMA package | Higher voltage rating and faster recovery, but double the forward current rating | Select when higher surge margin or tighter trr tolerance is required; may require layout adjustment due to larger SMA footprint |
| ES1J | VRRM = 600 V, trr = 35 ns, IF = 1.0 A, SMA package, no AEC-Q101 | Ultra-fast recovery and automotive-unqualified; lower VF (1.7 V typ) but higher leakage (10 µA) | Use in non-automotive consumer or industrial designs where speed outweighs qualification requirements |
Compared with STTH1L06S and ES1J, the RSFGLH offers AEC-Q101 qualification and optimized 400 V/0.5 A balance for cost-sensitive automotive auxiliary rails, whereas alternatives trade qualification for higher voltage, speed, or current capacity-requiring revalidation of thermal and EMI margins.

FAQ
What is the maximum junction temperature rating for RSFGLH?
The RSFGLH has a maximum junction temperature (TJMAX) of +150°C, verified per AEC-Q101 stress testing. This allows operation in under-hood automotive environments and sealed industrial enclosures. Derating begins at 25°C ambient, with full IF permitted only below 75°C ambient when using recommended PCB copper area. The RSFGLH datasheet specifies -55°C to +150°C storage and operating range.
Is RSFGLH qualified for automotive applications?
Yes, RSFGLH is AEC-Q101 qualified, having passed all required stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (UHAST). This qualification confirms its suitability for automotive power systems such as body control modules and lighting drivers. The RSFGLH marking code "FGL" and Sub SMA package are part of the qualified family per TSC document A2103.
What does the "FGL" in RSFGLH indicate?
The "FGL" in RSFGLH is the voltage code denoting 400 V VRRM, per TSC's RSF-series ordering convention: F = 400 V, G = 600 V, J = 800 V, etc. This code appears as the marking on the device body and aligns with the absolute maximum ratings table where RSFGLH is explicitly listed with VRRM = 400 V and trr = 150 ns. The RSFGLH data sheet version A2103 confirms this mapping.
What is the reverse recovery time test condition for RSFGLH?
The RSFGLH reverse recovery time (trr) is specified as 150 ns under the exact condition: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per Figure 6 and the Electrical Specifications table. This test setup reflects real-world switching behavior in flyback and forward converters. The RSFGLH value is distinct from RSFJLH (250 ns) and RSFKLH (500 ns) in the same family.
Does RSFGLH have halogen-free and RoHS-compliant construction?
Yes, RSFGLH uses halogen-free molding compound per IEC 61249-2-21 and is RoHS compliant, as stated in the FEATURES section of the official TSC datasheet (Version A2103). The Sub SMA package employs matte tin-plated leads meeting J-STD-002 solderability, and the entire construction is verified for lead-free reflow compatibility. These attributes are confirmed for the RSFGLH variant, not just the RSF-series family generally.
