Product details
Overview
TBS810 from Taiwan Semiconductor is a 1000V, 8A standard quad bridge rectifier with glass-passivated junctions, UL Recognized (E-326854), and RoHS/halogen-free compliance; used in high-voltage AC–DC conversion stages of switching mode power supplies.
For engineers reviewing the TBS810 datasheet, TBS810 pinout, TBS810 application, or TBS810 equivalent, key selection factors include peak reverse voltage (1000V), forward current rating (8A), thermal resistance (RθJL = 13°C/W), and TBS package compatibility with automated placement.
Technical Context
The TBS810 integrates four diodes in a single-phase bridge configuration, rated for repetitive peak reverse voltage of 1000V and surge current up to 475A (1ms). Its glass-passivated junction ensures stable performance under thermal cycling and humidity stress.
Thermal design is supported by RθJC = 9.2°C/W and RθJL = 13°C/W, measured on a 16mm × 16mm copper pad PCB; forward voltage is 0.97V max at 8A/25°C and 0.89V at 8A/125°C, enabling efficient operation across industrial temperature ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K (ON Semiconductor) | Same 1000V VRRM, 10A IF, but GBU package (larger footprint, higher RθJA) | Better current headroom but requires larger PCB area and additional thermal management | Select when higher continuous current (>8A) is needed and board space permits GBU outline |
| GBU8J (Vishay) | 8A IF, 600V VRRM, same GBU package; lower voltage rating limits use to 277VAC systems | Not suitable for 400VAC or surge-prone 230VAC lines where 1000V margin is required | Choose only for cost-sensitive, lower-voltage AC–DC designs where 600V blocking suffices |
Compared with GBU10K and GBU8J, the TBS810 uniquely balances 1000V blocking, 8A rating, and compact TBS surface-mount footprint-enabling high-density, thermally efficient rectification without sacrificing surge robustness or safety certification.

FAQ
What is the maximum repetitive peak reverse voltage rating for the TBS810?
The TBS810 has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, as confirmed in the Absolute Maximum Ratings table. This rating applies per diode within the quad bridge configuration and defines the highest sustained reverse voltage the device can block without breakdown under normal operating conditions at TA = 25°C.
Does the TBS810 meet RoHS and halogen-free requirements?
Yes, the TBS810 is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the official datasheet. These compliance attributes are verified for the TBS810 variant and apply to its standard production lot release.
What is the forward voltage drop of the TBS810 at 8A and 25°C?
The forward voltage drop (VF) of the TBS810 is specified as 0.97 V maximum at IF = 8 A and TJ = 25°C, with typical value 0.90 V. This parameter is measured per diode under pulsed conditions (PW = 0.3 ms) and directly impacts conduction losses in the TBS810-based rectifier stage.
Is the TBS810 UL Recognized, and what is its file number?
Yes, the TBS810 is UL Recognized under File # E-326854, as documented in the FEATURES section. This recognition covers the entire TBS806–TBS810 family and confirms compliance with UL 60747-1 for discrete semiconductors, supporting end-product safety certification.
What is the thermal resistance from junction to lead (RθJL) for the TBS810?
The junction-to-lead thermal resistance (RθJL) of the TBS810 is 13°C/W, measured using the standard 16 mm × 16 mm copper pad test board per JEDEC JESD51-3. This value enables effective heat transfer from the die through the leads to an external heatsink or copper plane.
