Product details

Overview

GPA806H from Taiwan Semiconductor is an AEC-Q101-qualified 800V, 8A standard rectifier diode in TO-220AC package, designed for high-reliability power conversion stages in automotive and industrial DC/DC converters and switching inverters. It features low forward voltage (≤1.1 V at 8 A, 25°C), high surge capability (150 A, 8.3 ms), and junction-to-case thermal resistance of 2.5°C/W.

For engineers reviewing the GPA806H datasheet, GPA806H pinout, GPA806H application, or GPA806H equivalent, key selection factors include its 800 V repetitive peak reverse voltage, AEC-Q101 qualification status, TO-220AC mechanical compatibility, glass-passivated junction reliability, and thermal performance under sustained 8 A conduction.

Technical Context

The GPA806H is a single-die, standard (non-fast, non-soft-recovery) silicon rectifier optimized for line-frequency and medium-frequency switching applications up to ~100 kHz. Its 800 V V_RRM rating targets 400–600 V DC bus systems with safety margin, and its 150 A I_FSM supports robust inrush handling in SMPS front-ends.

Thermally, the device relies on case-mounted heatsinking via its TO-220AC package - the 2.5°C/W R_θJC enables efficient heat transfer from junction to heatsink surface, while the -55°C to +150°C operating range supports under-hood automotive environments when properly derated.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - Withstands peak reverse transients up to 800 V without breakdown; suitable for 600 V DC bus designs with 33% margin.
I_F	8 A continuous - Rated average forward current at case temperature ≤75°C; requires heatsink for full-load operation.
I_FSM	150 A (8.3 ms half-sine) - Handles cold-start surges and short-circuit stress in power supplies without failure.
V_F	≤1.1 V @ 8 A, 25°C - Low conduction loss improves efficiency in high-current rectification paths.
R_θJC	2.5°C/W - Enables predictable thermal design when mounted to heatsink; junction rise = 20°C per 8 W dissipated.
T_J max	+150°C - Supports operation in under-hood automotive locations with appropriate thermal management.
AEC-Q101	Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC-Q101 Rev D.

Pinout & Package

Package: TO-220AC - 3-lead, single-ended, through-hole package with isolated tab (cathode-connected tab). Matte tin-plated leads, UL 94V-0 molding compound, JESD201 Class 2 whisker compliant.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Input current entry	Connected to AC or switched node; must withstand full reverse voltage when off.
Cathode (Lead 2)	Output current exit	Electrically tied to metal tab; primary heat path to heatsink; polarity-marked on device body.

High surge current capability	150 A non-repetitive surge rating allows use in unregulated input stages without external fusing.
Low thermal resistance	2.5°C/W R_θJC reduces required heatsink size by ~30% vs. comparable 3.5°C/W devices at same power dissipation.
Halogen-free & RoHS	Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained supply chains.

FAQ

What is the peak repetitive reverse voltage rating of the GPA806H?

The GPA806H has a repetitive peak reverse voltage (V_RRM) rating of 800 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2103), and defines the maximum instantaneous reverse voltage the device can block repeatedly without breakdown. It is specifically assigned to the GPA806H variant within the GPA801–GPA807 family.

Is the GPA806H AEC-Q101 qualified, and what does that mean for automotive use?

Yes, the "H" suffix in GPA806H explicitly denotes AEC-Q101 qualification per the Ordering Information section of the datasheet. This means the GPA806H has passed stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock - validating its suitability for automotive powertrain and chassis applications where reliability under extreme thermal and vibration conditions is mandatory.

What is the forward voltage drop of the GPA806H at rated current?

The GPA806H exhibits a maximum forward voltage (V_F) of 1.1 V at 8 A forward current and 25°C junction temperature, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (0.3 ms pulse width) and represents the conduction loss under typical operating conditions - critical for calculating power dissipation and thermal design.

Does the GPA806H have an isolated tab, and how should it be mounted?

No, the GPA806H uses a TO-220AC package with a cathode-connected tab - the metal tab is electrically common with Pin 2 (cathode), not isolated. When mounting to a grounded heatsink, an insulating washer and shoulder washer must be used to prevent short circuits. The datasheet's Mechanical Data section confirms polarity marking and tab connectivity.

What is the junction-to-case thermal resistance of the GPA806H, and why does it matter?

The GPA806H has a typical junction-to-case thermal resistance (R_θJC) of 2.5°C/W, per the Thermal Performance table. This parameter directly determines how much the junction temperature rises above the case temperature for a given power dissipation - enabling accurate heatsink sizing and ensuring safe operation below the +150°C maximum junction limit under real-world load conditions.
