Product details
Overview
ABS6-K from Taiwan Semiconductor is a 1 A, 600 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 compact switching power supplies.
For engineers reviewing the ABS6-K datasheet, ABS6-K pinout, ABS6-K application, or ABS6-K equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward current rating (1.0 A on aluminum substrate), thermal resistance (RθJL = 25 °C/W), and RoHS/halogen-free compliance for industrial adapter and lighting designs.
Technical Context
The ABS6-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.
Designed for surface-mount assembly on FR-4 or aluminum substrates, it supports 1.0 A continuous forward current when mounted on thermally enhanced PCBs and withstands 8.3 ms half-sine surge currents up to 30 A, with fusing I²t rating of 3.74 A²s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse voltage the device blocks per cycle; defines usable input AC range (e.g., 420 VRMS line). |
| IF | 1.0 A - Continuous forward current rating when mounted on aluminum substrate; determines max DC output current in SMPS front-end. |
| IFSM | 30 A - Peak non-repetitive surge current (8.3 ms half-sine); enables robustness against line transients and inrush events. |
| VF | ≤0.95 V - Max forward voltage per diode at 0.4 A and 25°C; directly impacts conduction loss and thermal rise in bridge leg. |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance; enables accurate junction temperature estimation using lead temperature measurement. |
| TJ max | 150 °C - Maximum allowable junction temperature; sets upper limit for thermal design margin in enclosed adapters. |

Applications
| Switching Mode Power Supply (SMPS) | AC/DC Adapters |
|---|---|
Use Scenario: Front-end rectification in 10–30 W offline flyback converters powering IoT gateways and smart home hubs. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting universal AC input (85–265 VAC) to pulsating DC for bulk capacitor charging. Use Value: 600 V VRRM provides 2× safety margin over 265 VAC peak (375 V), while 30 A IFSM handles cold-start surges without degradation. | Use Scenario: Compact wall-mounted USB-C PD adapters with dual-output rails (5 V/9 V/15 V/20 V). IC Role / Device Role / Timing Role: Input-stage AC/DC conversion before active PFC or primary-side controller IC. Use Value: ABS package enables low-profile design (<2.3 mm height); 1.0 A IF rating supports up to 24 W continuous output with adequate thermal margin on 2-layer PCB. |
| LED Lighting Drivers | Industrial Control Power Supplies |
Use Scenario: Constant-current LED drivers for commercial troffer and panel lights operating from 120/230 VAC. IC Role / Device Role / Timing Role: Non-isolated bridge rectifier feeding buck or buck-boost LED controller ICs. Use Value: Glass passivation ensures long-term stability under high ambient temperatures (>85°C enclosure), with <150 µA IR at 125°C limiting standby losses. | Use Scenario: Auxiliary power supply for PLC I/O modules requiring reliable 5 V/12 V bias rails. IC Role / Device Role / Timing Role: Primary-side rectification in isolated flyback or forward converter supplying control logic and sensors. Use Value: UL recognition simplifies system-level safety approval; RθJL = 25 °C/W allows junction temp monitoring via solder joint thermocouple during qualification testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 600 V VRRM, 1.5 A IF, but GBU package (larger footprint, higher RθJA = 50 °C/W). | Preferred where higher continuous current headroom is needed, but requires PCB layout revision due to larger body and lead spacing. | Select GBU6K only if >1.0 A sustained load current or lower ambient thermal conditions justify package change. |
| DB106S (Diotec) | 600 V VRRM, 1.0 A IF, same ABS package, but no UL recognition and higher typical VF (1.05 V). | Suitable for cost-sensitive, non-certified industrial equipment where UL listing is not required. | Choose DB106S for BOM cost reduction in non-regulated markets, accepting trade-off in safety certification and conduction loss. |
Compared with GBU6K and DB106S, ABS6-K uniquely balances UL recognition, ABS footprint, and 1.0 A/600 V rating-making it optimal for certified, space-constrained AC/DC designs where thermal performance and regulatory compliance are jointly critical.

FAQ
What is the maximum continuous forward current rating for ABS6-K?
The ABS6-K has a maximum continuous forward current (IF) of 1.0 A when mounted on an aluminum substrate, and 0.8 A on standard glass-epoxy PCBs. This rating is defined at TA = 25°C and must be derated above 25°C per the forward current derating curve in the ABS6-K datasheet. Thermal design must ensure junction temperature remains ≤150°C under worst-case load and ambient conditions.
Does ABS6-K have UL recognition, and what is the file number?
Yes, ABS6-K is UL Recognized under file number E-326854. This applies to the entire ABS4-K through ABS10-K family and confirms compliance with UL 60747-4 for semiconductor devices. The recognition covers flammability (UL 94V-0), terminal plating (J-STD-002), and whisker resistance (JESD 201 Class 1A), supporting end-product safety certifications without additional component-level evaluation.
What is the marking code printed on the ABS6-K device body?
The ABS6-K device is marked "ABS6" on its top surface, followed by date code (YW) and factory code (F). This marking aligns with the ordering code ABS6-K and distinguishes it from other members of the family (e.g., ABS4-K shows "ABS4", ABS8-K shows "ABS8"). Polarity is indicated by the "+" and "–" symbols adjacent to respective terminals.
What is the peak forward surge current rating for ABS6-K, and under what test condition?
The ABS6-K has a peak forward surge current (IFSM) rating of 30 A, tested using an 8.3 ms single half-sine wave superimposed on rated load. This value is specified at TA = 25°C and reflects the device's ability to survive transient overloads such as AC line surges or capacitor inrush. The corresponding fusing I²t rating is 3.74 A²s, useful for coordinating with upstream fuses.
Is ABS6-K compliant with RoHS and halogen-free standards?
Yes, ABS6-K is RoHS compliant and halogen-free per IEC 61249-2-21. All materials-including molding compound, lead frame, and plating-meet these requirements. The device carries no restricted substances above threshold limits and is suitable for export to EU, China, and other regulated markets requiring formal declarations of conformity.
