Product details
Overview
TBS410 from Taiwan Semiconductor is a 4A, 1000V standard quad bridge rectifier with glass-passivated junctions, UL Recognized (E-326854), and RoHS/halogen-free compliance; it delivers 110A surge current handling and operates up to 150°C junction temperature in SMPS front-end rectification.
For engineers reviewing the TBS410 datasheet, TBS410 pinout, TBS410 application, or TBS410 equivalent, key selection criteria include peak reverse voltage (1000V), forward voltage at 4A/25°C (≤1.00V), thermal resistance (RθJL = 13°C/W), and TBS package compatibility with automated placement and J-STD-002 solderability.
Technical Context
The TBS410 integrates four silicon diodes in a single-phase full-wave bridge configuration within a molded TBS package, supporting AC-to-DC conversion without external interconnects. Its glass-passivated junction ensures stable reverse leakage (<2 µA at 25°C, <200 µA at 125°C) and robust surge capability (IFSM = 110A @ 8.3ms).
Thermal performance is defined for PCB mounting on a 16mm × 16mm copper pad: RθJL = 13°C/W enables efficient heat transfer to the PCB lead frame, while RθJA = 50°C/W reflects ambient-limited dissipation under standard test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage per diode; defines safe AC input voltage ceiling (e.g., 700 VRMS line) before breakdown. |
| IF | 4 A - Continuous average forward current rating; supports sustained DC output of ~4A after rectification with appropriate heatsinking. |
| IFSM | 110 A - Non-repetitive surge current (8.3 ms sine half-cycle); withstands inrush and transient overloads in power supplies. |
| VF @ 4A, 25°C | ≤1.00 V - Forward voltage drop per diode; determines conduction loss (≈4W total for bridge at 4A) and thermal design margin. |
| RθJL | 13 °C/W - Junction-to-lead thermal resistance; enables direct thermal path to PCB copper, critical for compact high-power layouts. |
| Junction Temp | –55°C to +150°C - Operating range compatible with industrial and extended-temperature environments without derating. |
| CJ | 38 pF - Junction capacitance per diode at 1 MHz / 4V; impacts high-frequency switching noise and EMI filter design. |
Pinout & Package
Package: TBS - Molded plastic case with matte tin-plated leads, UL 94V-0 rated, polarity marked on top surface, weight ≈0.220 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | Same 4A/1000V rating, GBU package (larger footprint, higher RθJA = 65°C/W), no UL recognition cited. | Requires larger PCB area; less suitable for space-constrained designs where TBS footprint is optimized. | Select when legacy GBU layout exists and UL certification is not required. |
| GBU4J (Vishay) | 4A/600V rating (lower VRRM), same GBU package; IFSM = 120A but insufficient for 277VAC+ systems. | Not rated for 1000V line transients; limited to ≤230VAC nominal inputs. | Choose only for lower-voltage global-input adapters where 600V margin suffices. |
Compared with GBU4K and GBU4J, the TBS410 provides verified 1000V isolation, UL recognition, and superior thermal efficiency in a compact TBS package-making it optimal for high-reliability, space-sensitive, and safety-certified AC-DC front ends.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) specified for the TBS410?
The TBS410 has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2103). This rating allows the TBS410 to safely operate across universal AC input ranges including 277VAC line systems with transient margins. The TBS410 maintains this rating across its full operating temperature range.
Does the TBS410 require pre-reflow baking before SMT assembly?
No, the TBS410 does not require pre-reflow baking because it is rated at Moisture Sensitivity Level (MSL) 1 per J-STD-020. This means the device can be stored indefinitely at ambient conditions and placed directly into reflow without moisture-related risk. The TBS410's MSL 1 status is explicitly stated in the Features section of the Taiwan Semiconductor datasheet.
Is the TBS410 UL Recognized, and what is its file number?
Yes, the TBS410 is UL Recognized under File # E-326854, as documented in the Features section of the official Taiwan Semiconductor datasheet. This recognition applies to the entire TBS406–TBS410 family and validates compliance with UL 60747-1 for discrete semiconductors, supporting end-product safety certifications in North America.
What is the forward voltage (VF) of the TBS410 at 4A and 25°C?
The forward voltage (VF) of the TBS410 is guaranteed ≤1.00 V at 4A and 25°C, per the Electrical Specifications table. This value represents the maximum drop per diode under pulsed test conditions (PW = 0.3ms), and actual typical performance is 0.95 V. The TBS410 maintains lower VF (≤0.96 V) even at elevated junction temperatures (125°C).
What package type does the TBS410 use, and what are its key mechanical attributes?
The TBS410 uses the TBS package-a surface-mount molded plastic case with matte tin-plated leads. Key mechanical attributes include UL 94V-0 flammability rating, J-STD-002 solderability, JESD 201 Class 1 whisker resistance, and polarity marking on the top surface. Its approximate weight is 0.220 g, and the suggested pad layout is provided in the Package Outline Dimensions drawing of the TBS410 datasheet.
