Product details
Overview
1N5407GH from Taiwan Semiconductor is a glass-passivated, AEC-Q101 qualified standard silicon rectifier diode in DO-201AD package, rated for 3A average forward current, 800V repetitive peak reverse voltage, and 125A non-repetitive surge current - used in automotive-grade DC-DC converters and switching inverters.
For engineers reviewing the 1N5407GH datasheet, 1N5407GH pinout, 1N5407GH application, or 1N5407GH equivalent, key selection criteria include its 800V VRRM, 1.0V max forward voltage at 3A, 5µA max reverse leakage at 25°C, AEC-Q101 qualification, and DO-201AD mechanical compatibility with high-reliability power conversion designs.
Technical Context
This single-die, axial-leaded rectifier operates as a unidirectional current-conducting device with a PN junction optimized for high-surge capability and low conduction loss. Its glass passivation ensures stable surface characteristics under thermal cycling and humidity stress.
The 1N5407GH supports continuous operation up to +150°C junction temperature and exhibits 15°C/W junction-to-case thermal resistance, enabling reliable performance in compact, convection-cooled power supplies without forced airflow.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L08S | TO-220AC package, 3A/800V, 1.7V VF, no AEC-Q101 | Requires heatsink mounting; higher conduction loss; not automotive-qualified | Preferred where board space allows TO-220 and thermal budget permits higher VF |
| ON Semi MUR480E | DO-201AD, 4A/800V, ultrafast recovery (75ns), 1.75V VF, no AEC-Q101 | Higher speed enables higher-frequency SMPS but with greater conduction loss and no automotive validation | Select when switching frequency exceeds 100kHz and surge immunity is secondary to recovery time |
Compared with STTH3L08S and MUR480E, the 1N5407GH delivers lower forward loss (1.0V vs. ≥1.7V), inherent DO-201AD board-level compatibility, and AEC-Q101 validation - making it optimal for cost-sensitive, thermally constrained, and automotive-compliant 50–100kHz rectification tasks.

FAQ
What is the peak repetitive reverse voltage rating for the 1N5407GH?
The 1N5407GH has a repetitive peak reverse voltage (VRRM) rating of 800 V. This value is specified in the Absolute Maximum Ratings table and defines the maximum reverse-biased voltage the diode can block repeatedly without entering avalanche breakdown. It is verified per JEDEC test conditions and applies across the full operating temperature range.
Is the 1N5407GH qualified to AEC-Q101 standards?
Yes, the 1N5407GH is explicitly AEC-Q101 qualified, as confirmed by the "H" suffix in its ordering code and documented in Taiwan Semiconductor's K2105 datasheet revision. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing - validating suitability for automotive power electronics.
What is the forward voltage drop of the 1N5407GH at 3A and 25°C?
The 1N5407GH has a maximum forward voltage (VF) of 1.0 V at 3 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (0.3 ms pulse width) and represents the upper limit for conduction loss in low-frequency rectification applications.
Does the 1N5407GH have a defined thermal resistance from junction to ambient?
Yes, the 1N5407GH has a typical junction-to-ambient thermal resistance (RθJA) of 45°C/W under free-air conditions, as stated in the Thermal Performance section. This value assumes standard PCB mounting with minimal copper area; actual RθJA will improve with added copper pour or heatsinking.
What packaging options are available for the 1N5407GH?
The 1N5407GH is supplied in DO-201AD package with two standard packing formats: 1,250 pieces per tape-and-reel (ordering code 1N5407GH) and 500 pieces per ammo box (ordering code 1N5407GHA0G). Both use pure tin-plated leads compliant with J-STD-002 solderability requirements.
