Product details
Overview
ABS4HREG from Taiwan Semiconductor is a 1A, 400V AEC-Q101-qualified standard bridge rectifier in ABS package, featuring glass-passivated junctions, 30A peak surge current capability, and UL Recognized File #E-326854 - used in automotive-grade AC/DC front-end conversion for lighting and adapters.
For engineers reviewing the ABS4HREG datasheet, ABS4HREG pinout, ABS4HREG application, or ABS4HREG equivalent, key selection criteria include repetitive peak reverse voltage (400V), forward current rating (1.0A on aluminum substrate), thermal resistance (RθJL = 25°C/W), and AEC-Q101 qualification status for automotive reliability validation.
Technical Context
This quad-configuration bridge rectifier integrates four silicon diodes in a single-phase full-wave topology, enabling AC-to-DC conversion without external interconnection. Its glass-passivated junction ensures stable leakage performance up to 125°C (IR ≤ 150 µA) and supports automated SMT placement per J-STD-002 solderability requirements.
The ABS4HREG operates with a maximum junction temperature of 150°C and exhibits RθJA = 80°C/W on standard FR-4, requiring thermal management consideration in high-power-density designs. Its 3.74 A²s fusing rating defines safe single-pulse surge handling under 8.3 ms half-sine conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage per diode; determines minimum AC input isolation margin in SMPS front-end design. |
| IF | 1.0 A (on aluminum substrate) - Continuous forward current derating basis; requires heatsinking above ~60°C ambient. |
| IFSM | 30 A - Peak non-repetitive surge current (8.3 ms); supports inrush current handling in LED driver and adapter inputs. |
| TJ max | 150 °C - Absolute maximum junction temperature; sets upper limit for thermal design and reliability modeling. |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance; enables direct thermal path estimation when mounted to metal-core PCBs. |
| VF (per diode) | ≤ 0.95 V @ IF = 0.4 A, TJ = 25°C - Forward voltage drop impacts conduction loss and efficiency in low-voltage-output supplies. |
| IR (per diode) | ≤ 10 µA @ VR = 400 V, TJ = 25°C - Low leakage ensures minimal standby power loss in energy-sensitive lighting applications. |
Pinout & Package
Package: ABS - molded plastic case meeting UL 94V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~AC1 | AC input terminal 1 | One leg of AC input; connects to transformer secondary or EMI filter output in full-wave bridge configuration. |
| ~AC2 | AC input terminal 2 | Second leg of AC input; polarity-independent - interchangeable with ~AC1 for bidirectional AC line connection. |
| +DC | Positive DC output | Anode of internal diode pair; delivers rectified positive rail to bulk capacitor or downstream converter stage. |
| –DC | Negative DC output | Cathode of internal diode pair; forms return path for DC load current and reference for output regulation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and UHAST - required for under-hood and exterior lighting modules. |

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 400V VRRM, 1.5A IF, but GBU package (larger footprint, higher RθJA = 100°C/W); not AEC-Q101 qualified. | Suitable for industrial/non-automotive adapters where qualification is not mandated. | Select when higher continuous current margin is needed and automotive qualification is unnecessary. |
| ABS4M (Taiwan Semiconductor) | Identical ABS package and electrical specs, but lacks AEC-Q101 qualification and UL recognition; moisture sensitivity level 1 retained. | Acceptable for cost-sensitive consumer lighting where automotive reliability and safety certifications are waived. | Choose only if AEC-Q101 and UL E-326854 are not required by end-equipment standards. |
Compared with GBU4K and ABS4M, ABS4HREG uniquely combines AEC-Q101 qualification, UL recognition, and ABS-package thermal efficiency - making it the sole option for automotive exterior lighting and safety-critical industrial adapters requiring certified reliability and traceable compliance.

FAQ
What is the peak forward surge current rating for ABS4HREG?
The ABS4HREG has a peak forward surge current (IFSM) rating of 30 A for an 8.3 ms single half-sine wave. This value is confirmed in the Absolute Maximum Ratings table and applies under rated load conditions. The ABS4HREG uses this surge capability to handle inrush currents during cold start in LED drivers and adapters without degradation. Its 3.74 A²s fusing rating further defines safe single-pulse energy limits.
Is ABS4HREG suitable for automotive applications?
Yes, ABS4HREG is explicitly AEC-Q101 qualified and intended for automotive applications including exterior lighting and under-hood power modules. Its qualification covers temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress testing (UHAST). The ABS4HREG also meets UL Recognition File #E-326854 and halogen-free requirements per IEC 61249-2-21 - all documented in Taiwan Semiconductor's M2103 datasheet revision.
What is the forward voltage drop of ABS4HREG at typical operating conditions?
The ABS4HREG exhibits a maximum forward voltage (VF) of 0.95 V per diode at IF = 0.4 A and TJ = 25°C, measured under 0.3 ms pulse conditions. This value directly impacts conduction losses in the rectifier stage. At full rated current (1.0 A), VF increases due to resistive heating, and system-level thermal design must account for this to maintain efficiency and junction temperature within the 150°C limit.
Does ABS4HREG require moisture preconditioning before reflow soldering?
No, ABS4HREG has a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it has unlimited floor life and does not require baking or dry-pack handling prior to reflow. This simplifies manufacturing logistics and eliminates risk of popcorning during lead-free reflow profiles. The ABS4HREG's molded ABS package and matte tin-plated leads are fully compatible with standard J-STD-002 solderability requirements.
What is the thermal resistance from junction to ambient for ABS4HREG?
The ABS4HREG has a junction-to-ambient thermal resistance (RθJA) of 80°C/W when mounted on standard FR-4 PCB per datasheet test conditions. This value assumes no additional copper pour or heatsinking. For improved thermal performance, designers should use the specified pad layout and consider mounting on aluminum substrates - where RθJA drops significantly and the device supports its full 1.0 A rating up to 60°C ambient.
