Product details
Overview
EABS1G from Taiwan Semiconductor is a 1A, 400V super fast bridge rectifier in ABS package, featuring 35ns reverse recovery time, 40A peak surge current, and AEC-Q101 qualification option; used in compact SMPS and lighting adapters requiring high-frequency rectification with low leakage.
For engineers reviewing the EABS1G datasheet, EABS1G pinout, EABS1G application, or EABS1G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), forward voltage (1.20 V max at 1 A), thermal resistance (25 °C/W junction-to-lead), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The EABS1G integrates four silicon diodes in a single-phase full-wave bridge configuration with quad anode-cathode topology, enabling direct AC-to-DC conversion without external interconnection. Its super fast trr of 35 ns supports switching frequencies up to several hundred kHz in resonant and quasi-resonant converters.
Thermal performance is defined by RθJL = 25 °C/W and RθJA = 80 °C/W, with junction temperature rated from –55 °C to +150 °C. The device uses matte tin-plated leads compliant with J-STD-002 and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse voltage per diode; defines safe AC input voltage limit (e.g., 280 V RMS) |
| IF | 1 A - continuous average forward current; sets DC output capability under thermal derating |
| trr | 35 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A; enables high-frequency operation with low switching loss |
| IFSM | 40 A - non-repetitive surge current (8.3 ms half-sine); withstands inrush in SMPS startup |
| RθJL | 25 °C/W - junction-to-lead thermal resistance; determines heatsinking requirement for lead-mounted PCB layout |
| IR | 1 µA max at 25 °C - reverse leakage per diode; ensures minimal standby power loss in offline supplies |

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) | 400 V VRRM, 4 A IF, 50 ns trr, GBU package (larger than ABS) | Higher current rating but slower recovery; suited for lower-frequency, higher-power designs | Select when >1 A average current or higher surge margin is needed; requires larger PCB footprint |
| DF04S (Vishay) | 400 V VRRM, 1 A IF, 500 ns trr, DFS package (similar size to ABS) | Standard recovery vs. super fast; higher VF (~1.3 V) and greater switching loss at >100 kHz | Select for cost-sensitive, low-frequency (<50 kHz) applications where trr is not critical |
Compared with GBU4K and DF04S, the EABS1G delivers superior high-frequency efficiency due to its 35 ns trr and optimized thermal resistance, while maintaining the smallest footprint among 1 A, 400 V bridge options-making it optimal for space-constrained, high-efficiency SMPS designs.

FAQ
What is the maximum operating junction temperature for EABS1G?
The EABS1G has a maximum junction temperature (TJ) of +150 °C, with a minimum of –55 °C. This wide range allows reliable operation in environments such as enclosed LED drivers or industrial control cabinets without forced cooling. Derating curves in the datasheet define usable current versus ambient temperature, and the 25 °C/W junction-to-lead thermal resistance supports efficient heat transfer through PCB copper.
Is EABS1G pin-compatible with other ABS-packaged bridge rectifiers like DB107 or GBU4K?
No, EABS1G is not pin-compatible with DB107 (DB package, 4-pin inline) or GBU4K (GBU package, 4-pin inline with different lead spacing). The ABS package has a unique 10.5 mm × 8.0 mm outline and 2.54 mm lead pitch. Pin assignments (AC1, AC2, +, –) match standard bridge orientation, but physical dimensions and solder pad layout must be verified using TSC's ABS package drawing before substitution.
Does EABS1G meet RoHS and halogen-free requirements?
Yes, EABS1G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated per J-STD-002. These specifications are confirmed in the official Taiwan Semiconductor datasheet Version C2103 and apply to all standard EABS1G units-not only the AEC-Q101-qualified EABS1GH variant.
What is the typical forward voltage drop of EABS1G at rated current?
The EABS1G has a maximum forward voltage (VF) of 1.20 V per diode at IF = 1 A and TJ = 25 °C, measured under pulsed conditions (PW = 0.3 ms). At elevated junction temperatures (e.g., 125 °C), VF decreases slightly due to semiconductor physics, but total bridge conduction loss remains well below 2.5 W at full load under proper thermal design.
Can EABS1G be used in place of EABS1D or EABS1J in a design?
EABS1G (400 V VRRM) is not a direct replacement for EABS1D (200 V) or EABS1J (600 V) without circuit review. Substituting EABS1G for EABS1D risks overvoltage failure in 277 V AC applications; substituting for EABS1J may compromise safety margin in 480 V industrial systems. Voltage rating must match system peak line voltage plus safety margin-EABS1G is validated for 230/240 V AC mains with transient allowance.
