Product details
Overview
GBU807H from Taiwan Semiconductor is an AEC-Q101 qualified standard bridge rectifier in GBU package, rated for 8A average forward current, 1000V repetitive peak reverse voltage (VRRM), and 200A non-repetitive surge current (IFSM), used in automotive-grade AC/DC front-end conversion stages of on-board chargers and lighting drivers.
For engineers reviewing the GBU807H datasheet, GBU807H pinout, GBU807H application, or GBU807H equivalent, key selection criteria include VRRM rating, thermal resistance (RθJC = 2°C/W), junction temperature range (–55°C to +150°C), AEC-Q101 qualification status, and UL recognition (E-326243).
Technical Context
The GBU807H integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode/common-anode topology. Its 1000V VRRM rating enables direct use in universal-input (85–265VAC) and high-line industrial AC mains interfaces without external voltage derating.
Thermal design is supported by low junction-to-case resistance (2°C/W) and high case dielectric strength (1500VRMS), allowing reliable operation at TJ up to 150°C under forced-air or PCB copper pour cooling in compact power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports direct connection to 700VDC bus or 600VAC RMS line without additional snubbing |
| IF(AV) | 8 A - delivers continuous DC output current up to 8A at TC ≤ 75°C with adequate heatsinking |
| IFSM | 200 A - withstands 8.3ms half-sine surges typical of inrush current in SMPS input stages |
| RθJC | 2 °C/W - enables efficient heat transfer to heatsink or metal-core PCB, critical for automotive under-hood thermal environments |
| IR @ 125°C | 500 µA - ensures minimal leakage-induced standby loss in high-temperature lighting and EVSE applications |
| CJ (per diode) | 94 pF - reduces high-frequency switching noise coupling in PFC and flyback converters operating above 50kHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBU8K | VRRM = 800V (vs. 1000V); same IF = 8A, IFSM = 200A, GBU package | Not rated for 600VAC line systems requiring 1000V margin; suitable for 400VAC max inputs | Select GBU807H when designing for universal input (85–265VAC) with >2× safety margin or 700VDC bus interfaces |
| ON Semiconductor GBPC807 | Same VRRM = 1000V, IF = 8A, but in GBPC (4-pin DIP) package; no AEC-Q101 qualification | Lacks automotive qualification; higher RθJA (25°C/W vs. 21°C/W) limits power density in constricted layouts | Choose GBU807H for automotive or thermally demanding industrial designs where AEC-Q101 and lower RθJC are mandatory |
Compared with GBU8K and GBPC807, the GBU807H uniquely combines 1000V VRRM, AEC-Q101 qualification, and 2°C/W RθJC-enabling smaller heatsinks, longer lifetime in automotive thermal cycles, and compliance with ISO 16750-4 load-dump immunity requirements.

FAQ
What does the "H" suffix in GBU807H signify?
The "H" suffix in GBU807H indicates full AEC-Q101 qualification per Rev-D stress test requirements-including high-temperature operating life (HTOL), temperature cycling (TCT), and highly accelerated stress test (HAST). This distinguishes it from the standard GBU807, which lacks automotive qualification and is intended for commercial-grade applications only.
Is GBU807H pin-compatible with other GBU-series rectifiers like GBU804H?
Yes, all GBU-series rectifiers-including GBU807H and GBU804H-share identical GBU package dimensions, lead spacing, and 4-terminal pinout (AC1, AC2, +, –). However, VRRM differs (1000V vs. 400V), so substitution requires verification of reverse voltage margin in the target circuit.
What is the maximum recommended case temperature for continuous operation of GBU807H?
The GBU807H supports continuous operation up to TC = 125°C when mounted on a minimum 10 cm² copper pad (2 oz) with thermal vias. At this case temperature, the junction remains within its 150°C limit given RθJC = 2°C/W, enabling reliable performance in sealed automotive enclosures without forced airflow.
Does GBU807H meet UL safety certification requirements?
Yes, GBU807H is UL Recognized under File #E-326243, confirming compliance with UL 60747-4 for semiconductor devices and supporting end-equipment certification for Class I and Class II power supplies in North America without additional component-level investigation.
How does the junction capacitance of GBU807H affect EMI in high-frequency SMPS designs?
With CJ = 94 pF per diode at 1MHz and VR = 4V, the GBU807H contributes low displacement current during switching transitions. This minimizes high-frequency common-mode noise injection into EMI filters-especially beneficial in >100kHz flyback and resonant converters where diode capacitance directly impacts conducted emissions above 30MHz.
