Product details
Overview
ABS10-K from Taiwan Semiconductor is a 1 A, 1000 V standard bridge rectifier in ABS package with quad configuration, glass-passivated junctions, 30 A peak surge capability, and UL recognition (E-326854), used in AC/DC front-end stages of offline SMPS and LED drivers.
For engineers reviewing the ABS10-K datasheet, ABS10-K pinout, ABS10-K application, or ABS10-K equivalent, key selection criteria include repetitive peak reverse voltage (1000 V), forward current rating (1.0 A on aluminum substrate), thermal resistance (RθJL = 25 °C/W), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
The ABS10-K integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling direct AC-to-DC conversion without external interconnection. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C) and high reliability under thermal cycling.
Rated for operation from –55°C to +150°C junction temperature, it supports high-temperature PCB layouts and delivers 3.74 A²s fusing I²t rating under 8.3 ms half-sine surge, making it suitable for transient-heavy mains-input applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage per diode; defines maximum AC input RMS voltage support (~700 VRMS) |
| IF | 1.0 A - Continuous forward current rating on aluminum substrate; determines heatsink-free power handling up to ~1.2 W dissipation |
| IFSM | 30 A - Non-repetitive peak surge current (8.3 ms); withstands inrush currents in switch-mode adapters and lighting ballasts |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance; enables direct thermal path to PCB copper pour or heatsink via leads |
| VF (per diode) | ≤0.95 V @ 0.4 A - Forward voltage drop limits conduction loss and self-heating in 50/60 Hz rectification |
| IR (per diode) | ≤10 µA @ 25°C - Low reverse leakage preserves efficiency in high-impedance hold-up circuits and standby modes |
| TJ max | +150°C - Maximum junction temperature; allows operation in enclosed, convection-limited environments |

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 1 A / 1000 V rating, GBU package (larger footprint, higher RθJA = 100 °C/W) | Requires larger PCB area and more thermal margin; not tape-and-reel compatible with ABS footprint | Select when legacy GBU layout exists and higher surge margin (50 A IFSM) is prioritized over size |
| DB107S (Diotec) | 1 A / 1000 V, DBS package (smaller than ABS), lower IFSM = 25 A, no UL recognition | Lacks UL file number; requires additional safety validation for end equipment; tighter thermal limits | Select for space-constrained consumer designs where UL recognition is not mandated |
Compared with GBU10K and DB107S, the ABS10-K offers optimal balance of compact ABS footprint, UL recognition, and 30 A surge rating-making it preferred for certified industrial and lighting power supplies requiring reliable, drop-in-ready rectification without layout redesign.

FAQ
What is the maximum continuous forward current rating for ABS10-K?
The ABS10-K has a continuous forward current rating of 1.0 A when mounted on an aluminum substrate, and 0.8 A on FR-4 glass-epoxy PCB. This rating reflects real-world thermal dissipation capability and must be applied with appropriate copper area or heatsinking to maintain junction temperature ≤150°C. Derating is required above ambient temperatures of 25°C per the forward current derating curve in the ABS10-K datasheet.
Does ABS10-K have UL recognition, and what is the file number?
Yes, ABS10-K is UL Recognized under file number E-326854. This certification confirms compliance with UL 60747-4 for semiconductor devices and supports streamlined end-equipment safety approvals in North America and other regions accepting UL recognition. The marking "UL" appears on the device body alongside the ABS10 code and date code.
What is the forward voltage drop specification for ABS10-K?
The ABS10-K specifies a maximum forward voltage of 0.95 V per diode at 0.4 A and 25°C junction temperature, measured under pulsed conditions (PW = 0.3 ms). This value directly impacts conduction losses in the rectifier stage; actual VF increases with current and temperature, reaching ~1.1 V at 1.0 A and 100°C.
Is ABS10-K compliant with RoHS and halogen-free standards?
Yes, ABS10-K is RoHS compliant and halogen-free per IEC 61249-2-21. All materials-including molding compound, lead frame, and plating-meet these environmental requirements. The device carries the "HF" marking on its top surface to indicate halogen-free status, and full compliance documentation is available from Taiwan Semiconductor upon request.
What is the peak non-repetitive forward surge current rating for ABS10-K?
The ABS10-K is rated for 30 A peak forward surge current (IFSM) under an 8.3 ms single half-sine wave condition. This rating applies to transient events such as AC power-on inrush or lightning-induced surges. The corresponding I²t rating is 3.74 A²s, which is used for fuse coordination and thermal stress analysis in the ABS10-K's application circuit.
