Taiwan Semiconductor Corporation 1N4003GHR0G

Overview

1N4003GHR0G from Taiwan Semiconductor is a glass-passivated silicon standard rectifier diode rated for 1 A average forward current and 200 V repetitive peak reverse voltage, with 30 A surge capability and 1 V max forward voltage at 1 A - used in DC-DC converters and switching inverters for reliable AC-to-DC power conversion.

For engineers reviewing the 1N4003GHR0G datasheet, 1N4003GHR0G pinout, 1N4003GHR0G application, or 1N4003GHR0G equivalent, key selection criteria include VRRM = 200 V, IFSM = 30 A, TJ(max) = 150 °C, VF ≤ 1 V @ 1 A, and DO-41 package compatibility with through-hole PCB layouts.

Technical Context

This discrete rectifier operates as a single-die, unidirectional PN junction device with glass-passivated chip construction ensuring stable reverse leakage (≤5 µA @ 25 °C, ≤100 µA @ 125 °C) and robust thermal performance (RθJA = 80 °C/W). Its DO-41 package supports manual or automated through-hole assembly.

The 1N4003GHR0G exhibits low junction capacitance (10 pF @ 4 V, 1 MHz), enabling use in moderate-frequency switching applications up to ~100 kHz without significant capacitive loss, while maintaining high reliability under repetitive surge conditions per JEDEC standards.

FAQ

What is the peak repetitive reverse voltage rating for 1N4003GHR0G?

The 1N4003GHR0G has a repetitive peak reverse voltage (VRRM) rating of 200 V. This value defines the maximum instantaneous reverse voltage the diode can block repeatedly without breakdown under normal operating conditions. It is verified per JEDEC test methods and applies across the full operating junction temperature range of −55 °C to +150 °C.

Does 1N4003GHR0G meet automotive reliability standards?

Yes, the "H" in 1N4003GHR0G indicates AEC-Q101 qualification. This means the 1N4003GHR0G has passed stress tests including temperature cycling, highly accelerated stress test (HAST), and mechanical shock - confirming suitability for automotive powertrain and body electronics where reliability under thermal and vibration stress is critical.

What is the forward voltage drop of 1N4003GHR0G at 1 A?

The 1N4003GHR0G exhibits a maximum forward voltage (VF) of 1.0 V at 1 A forward current and 25 °C junction temperature. This specification is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects and ensures predictable conduction loss in power supply output stages.

Is 1N4003GHR0G compatible with lead-free reflow soldering?

No - the 1N4003GHR0G uses pure tin-plated leads designed for wave or hand soldering per J-STD-002, not lead-free reflow. Its DO-41 package is rated for peak temperatures up to 260 °C for ≤10 seconds, but extended exposure above 235 °C risks lead finish degradation. For reflow processes, verify thermal profile against TSC's recommended soldering guidelines.

What does the "R0G" suffix mean in 1N4003GHR0G?

The "R0G" suffix in 1N4003GHR0G denotes tape-and-reel packaging: "R" = reel, "0" = standard orientation (anode first), "G" = green compound (halogen-free, RoHS-compliant molding). This differs from "A0G" (ammo box) and confirms the part is supplied in 5,000-unit reels ready for automated placement.
