Product details

Overview

GBL202H from Taiwan Semiconductor is a 2A, 100V AEC-Q101-qualified standard bridge rectifier in GBL package, featuring glass-passivated junctions, <1 μA reverse leakage at 25°C, and 60A non-repetitive surge capability. It serves as the AC-to-DC front-end in automotive-grade power adapters and lighting drivers.

For engineers reviewing the GBL202H datasheet, GBL202H pinout, GBL202H application, or GBL202H equivalent, key selection criteria include its 100V V_RRM, AEC-Q101 qualification, 13°C/W R_θJL, and matte tin-plated leads compliant with J-STD-002 solderability.

Technical Context

This quad-diode bridge integrates four silicon junctions in a single GBL molded package with common-cathode/common-anode configuration. Its glass passivation ensures stable reverse characteristics across -55°C to +150°C junction temperature range and supports high dielectric strength for isolation-critical SMPS inputs.

The device delivers 2A average forward current with ≤1.0 V forward voltage per diode at 2A/25°C, and exhibits 25 pF junction capacitance at 1 MHz/4 V - enabling low-noise rectification in high-frequency switching converters up to several hundred kHz.

Key Specifications

I_F	2 A - continuous average forward current; sets thermal design basis for heatsink-free operation up to ~50°C ambient
I_FSM	60 A - 8.3 ms half-sine surge rating; withstands inrush currents in LED driver and adapter startup
V_F (per diode)	≤1.0 V @ 2 A, 25°C - low conduction loss enables >85% efficiency in 12–24 V output SMPS
I_R (per diode)	≤5 μA @ 100 V, 25°C - minimal leakage preserves hold-up time and reduces standby power loss
R_θJL	13 °C/W - enables direct PCB copper pour thermal coupling without external heatsink for 2 A DC loads

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBL202	No AEC-Q101 qualification; identical electrical specs and package	Not suitable for automotive production; acceptable for industrial prototypes	Select GBL202H when automotive qualification or long-term field reliability is mandatory
DF04S	Same 2A/100V rating but SMD DO-214AA package; higher R_θJA (40°C/W)	Better for space-constrained layouts; requires thermal pad for same 2A load	Choose DF04S only if board area is critical and thermal management via PCB copper is impractical

Compared with GBL202 and DF04S, the GBL202H uniquely combines automotive qualification, through-hole GBL mechanical robustness, and low thermal resistance - making it optimal for high-reliability, thermally demanding bridge rectification where qualification and service life are prioritized over footprint size.

FAQ

What is the peak repetitive reverse voltage rating of the GBL202H?

The GBL202H has a peak repetitive reverse voltage (V_RRM) rating of 100 V. This value is defined per diode within the bridge and determines the maximum AC input voltage the device can safely block during each half-cycle. It corresponds to a 70 V_RMS sinusoidal input and is verified under standard test conditions per JEDEC JESD201.

Is the GBL202H suitable for automotive applications?

Yes, the GBL202H is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. This qualification covers stress tests including HTSL, TC, UHAST, and ESD, confirming suitability for automotive body electronics, lighting modules, and infotainment power supplies operating within -40°C to +125°C ambient ranges.

What is the forward voltage drop of the GBL202H at rated current?

The GBL202H exhibits a maximum forward voltage drop of 1.0 V per diode at 2 A and 25°C junction temperature. This specification is measured under pulsed conditions (0.3 ms pulse width) and reflects typical conduction loss in continuous operation - critical for calculating thermal rise and efficiency in 24 V-output SMPS designs using the GBL202H.

Does the GBL202H require a heatsink for 2A continuous operation?

No external heatsink is required for 2A continuous operation at ambient temperatures up to ~50°C, thanks to the GBL202H's 13°C/W junction-to-lead thermal resistance and GBL package's ability to transfer heat directly to PCB copper. Thermal performance must be validated in the final layout using measured board copper area and airflow conditions.

How does the GBL202H differ from the GBL202 part number?

The GBL202H differs from GBL202 solely by AEC-Q101 qualification - both share identical electrical parameters, package dimensions, pinout, and thermal ratings. The "H" suffix denotes additional automotive-grade screening and traceability. GBL202H is recommended for production automotive systems; GBL202 remains appropriate for cost-sensitive industrial applications where qualification is not mandated.
