Taiwan Semiconductor Corporation GP1602

Overview

GP1602 from Taiwan Semiconductor is a 16A, 100V standard rectifier diode in TO-220AB package, featuring dual-die construction, 150A surge capability, 1.1V max forward voltage at 8A/25°C, and AEC-Q101 qualification option. It serves as primary output rectification in automotive DC-DC converters and industrial switching inverters.

For engineers reviewing the GP1602 datasheet, GP1602 pinout, GP1602 application, or GP1602 equivalent, key selection factors include repetitive peak reverse voltage (100 V), junction-to-case thermal resistance (1.5 °C/W), forward voltage consistency across temperature, surge robustness (150 A IFSM), and RoHS/halogen-free compliance for automotive-grade deployment.

Technical Context

The GP1602 is a single-phase, silicon planar junction standard rectifier with dual-die configuration mounted in a TO-220AB thermally optimized package. Its 100 V VRRM rating targets mid-voltage DC-DC stages where efficiency and surge margin are critical.

Electrical behavior is defined by 1.1 V max VF at 8 A/25°C, 10 µA max IR at 25°C, and 50 pF typical junction capacitance at 1 MHz/4 V - parameters directly influencing conduction loss, leakage stability, and high-frequency switching noise in flyback and forward converter topologies.

FAQ

What is the maximum junction temperature rating for the GP1602?

The GP1602 has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official TSC datasheet. This allows sustained operation in high-ambient environments such as under-hood automotive locations or sealed industrial enclosures. Derating curves confirm 16 A continuous current is maintainable up to 75°C case temperature. The GP1602 must be mounted with appropriate thermal interface material and heatsinking to prevent exceeding TJ max during steady-state or surge conditions.

Is the GP1602 pin-compatible with other TO-220AB rectifiers like the STTH1602D?

Yes, the GP1602 uses the standard TO-220AB 3-lead mechanical outline with Anode–Cathode–Tab pinout, matching STTH1602D and most industry-standard 16 A rectifiers in that package. However, the metal tab is internally connected to the anode - unlike some variants with isolated tabs - so PCB layout must ensure proper anode-side isolation if mounting to a grounded heatsink. Always verify polarity marking and thermal pad connectivity before board-level substitution.

Does the GP1602 have AEC-Q101 qualification?

The GP1602 itself is not AEC-Q101 qualified, but its variant GP1602H is explicitly qualified per AEC-Q101 Rev D for automotive applications. GP1602H undergoes additional stress testing including HTGB, HTRB, and temperature cycling. For automotive designs requiring formal qualification, GP1602H must be specified - it shares identical electrical specs and TO-220AB packaging with GP1602, differing only in test documentation and part marking.

What is the forward voltage specification for the GP1602 at elevated temperature?

The GP1602 specifies VF ≤1.1 V max at IF = 8 A and TJ = 25°C. While the datasheet does not list a guaranteed max VF at higher temperatures, typical curves show VF decreases slightly with rising junction temperature due to silicon's negative temperature coefficient. At TJ = 125°C, measured VF is approximately 0.95–1.05 V under same conditions. Designers should use the 25°C max value for worst-case loss calculation unless performing detailed thermal modeling with actual TJ.

How does the dual-die structure of the GP1602 improve reliability compared to single-die rectifiers?

The GP1602's dual-die construction distributes forward current across two parallel silicon junctions, reducing localized heating and current crowding effects. This improves thermal uniformity, extends lifetime under cyclic loading, and enhances surge survivability - especially during repetitive IFSM events. Unlike single-die devices, failure of one die does not immediately disable the device, providing graceful degradation. The dual-die layout is internal and invisible externally; no change to footprint or pinout is required versus single-die equivalents.
