Taiwan Semiconductor Corporation 2A02GHR0G

Overview

2A02GHR0G from Taiwan Semiconductor is a 2 A, 100 V glass-passivated standard rectifier diode in DO-204AC (DO-15) package, featuring low forward voltage (1.1 V @ 2 A, 25°C), 70 A surge capability, and AEC-Q101 qualification for automotive use in DC-DC converters and switching inverters.

For engineers reviewing the 2A02GHR0G datasheet, 2A02GHR0G pinout, 2A02GHR0G application, or 2A02GHR0G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), junction-to-lead thermal resistance (25 °C/W), RoHS/halogen-free compliance, and cathode-band polarity marking for reliable board-level integration.

Technical Context

This discrete rectifier operates as a single-die, unidirectional current-conducting device with a maximum junction temperature of 150°C and storage range from –55°C to +150°C. Its glass-passivated junction ensures stable reverse leakage (<5 µA @ 25°C, <100 µA @ 125°C) and robust surge tolerance (70 A, 8.3 ms half-sine).

Thermal performance is defined by R_θJL = 25 °C/W and R_θJA = 60 °C/W, supporting conduction-cooled PCB layouts. The DO-204AC (DO-15) package uses pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

FAQ

What is the maximum junction temperature rating for 2A02GHR0G?

The 2A02GHR0G has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official TSC datasheet Version I2105. This rating enables operation in under-hood automotive environments and high-ambient industrial settings. Derating begins above 75°C ambient, and thermal design must maintain T_J ≤ 150°C under worst-case I_F and I_FSM conditions. The 2A02GHR0G's R_θJL = 25 °C/W supports this requirement when mounted on adequate copper area.

Is 2A02GHR0G pin-compatible with other DO-204AC rectifiers like 1N4007?

No - while both use DO-204AC (DO-15) mechanical packaging, the 2A02GHR0G is not functionally or electrically interchangeable with 1N4007. The 1N4007 is rated for 1 A / 1000 V with VF ≈ 1.1 V, whereas the 2A02GHR0G is rated for 2 A / 100 V with tighter VF distribution and AEC-Q101 qualification. Substitution requires validation of current, thermal, and qualification requirements. The 2A02GHR0G's marking "2A02G" and cathode band follow TSC-specific orientation conventions.

Does 2A02GHR0G meet automotive qualification standards?

Yes - the "H" suffix in 2A02GHR0G explicitly denotes AEC-Q101 qualification per the TSC ordering information table. This includes stress testing for temperature cycling, humidity bias, high-temperature operating life, and mechanical shock. The device is intended for automotive power supplies, body electronics, and ADAS subsystems where reliability under vibration, thermal cycling, and electrical transients is mandatory. The 2A02GHR0G's glass-passivated junction and JESD 201 Class 2 whisker resistance further support automotive-grade robustness.

What does the "R0G" suffix mean in 2A02GHR0G?

The "R0G" suffix in 2A02GHR0G indicates tape-and-reel packaging (R), green compound (G), and a specific date/lot coding format per TSC internal revision "R0". It does not alter electrical or thermal specifications. The base device remains the AEC-Q101-qualified 2A02GH rectifier. Packaging format affects handling, automated placement compatibility, and moisture sensitivity level (MSL), though DO-15 devices like the 2A02GHR0G are typically MSL-1 and do not require dry pack or bake-out prior to reflow.

How does the forward voltage of 2A02GHR0G compare across temperature?

The 2A02GHR0G exhibits a negative temperature coefficient for forward voltage: VF decreases as junction temperature rises. At 2 A and 125°C, VF drops to approximately 0.92 V versus 1.1 V at 25°C - confirmed by Fig.4 Typical Forward Characteristics in the TSC datasheet. This behavior reduces conduction loss at elevated temperatures but requires attention in thermal runaway analysis for parallel-connected diodes. The 2A02GHR0G's stable VF tracking across temperature supports predictable loss modeling in thermal simulation tools.
