Product details
Overview
1N4007G-K from Taiwan Semiconductor is a glass-passivated silicon standard rectifier diode rated for 1000 V repetitive peak reverse voltage (VRRM), 1 A average forward current (IF), and 30 A non-repetitive surge current (IFSM). It operates across –55°C to +150°C junction temperature and is used in DC-DC converters, switching-mode inverters, and general-purpose AC/DC front-end rectification.
For engineers reviewing the 1N4007G-K datasheet, 1N4007G-K pinout, 1N4007G-K application, or 1N4007G-K equivalent, key selection criteria include its 1000 V VRRM, 1 V max forward voltage at 1 A, 5 µA max reverse leakage at 25°C, DO-41 package compatibility, and RoHS/halogen-free compliance for industrial power supply designs.
Technical Context
This discrete rectifier uses a single-die silicon PN junction with glass passivation for enhanced moisture resistance and long-term reliability under thermal cycling. Its 80°C/W junction-to-ambient thermal resistance and 150°C maximum junction temperature support operation in compact, convection-cooled power stages.
The device exhibits low capacitance (10 pF at 4 V, 1 MHz) and stable reverse characteristics up to 700 V RMS, making it suitable for 50/60 Hz line-frequency rectification and moderate-speed switching applications where fast recovery is not required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports direct rectification of 700 V RMS AC mains or high-voltage DC bus conditioning |
| IF | 1 A continuous - sufficient for low-to-medium power SMPS outputs and auxiliary supplies |
| IFSM | 30 A (8.3 ms half-sine) - withstands inrush surges in transformer-coupled or capacitive-input rectifiers |
| VF max | 1.0 V @ 1 A, 25°C - limits conduction loss to ≤1 W at full load, enabling thermally constrained layouts |
| IR max | 5 µA @ 25°C, 1000 V - ensures minimal standby leakage in high-impedance hold-up or sensing circuits |
| TJ max | +150°C - allows operation in sealed enclosures or near heat-generating components without derating |
| CJ | 10 pF @ 4 V, 1 MHz - negligible capacitive loading on 50/60 Hz inputs; no EMI concerns in line-frequency use |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, glass-passivated body with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or lower-potential side during conduction; must handle full IF and IFSM |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to positive output rail; sustains full VRRM when reverse-biased |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Prevents moisture ingress and surface degradation, extending lifetime in humid or outdoor environments |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21; enables use in consumer, industrial, and green-energy products with strict material restrictions |
| UL 94V-0 molding compound | Self-extinguishing encapsulation reduces fire risk in overvoltage or overload fault conditions |
| J-STD-002 solderable leads | Ensures reliable reflow and hand-solder joints without lead finish oxidation or dewetting issues |
Applications
| AC/DC Power Adapter Input Stage | DC-DC Converter Output Rectification |
|---|---|
Use Scenario: Full-wave bridge rectification of 100–240 V AC input in wall adapters and open-frame PSUs. IC Role / Device Role / Timing Role: Discrete rectifier conducting during positive half-cycles; blocks reverse voltage during negative half-cycles. Use Value: 1000 V VRRM provides 2× safety margin over 240 V AC peak (≈340 V); 1 A rating covers typical ≤12 W output loads. | Use Scenario: Secondary-side freewheeling or output rectification in isolated flyback or forward converters. IC Role / Device Role / Timing Role: Unidirectional current path delivering regulated DC to output capacitor and load. Use Value: Low 1 V VF minimizes conduction loss at 1 A; 30 A IFSM absorbs transformer leakage energy during switch-off. |
| Industrial Control Power Supply | LED Driver Bulk Capacitor Charging |
Use Scenario: Auxiliary power generation from 24 V AC control rails or 48 V DC distribution buses. IC Role / Device Role / Timing Role: Half-wave or full-wave rectifier feeding linear regulator or buck converter input. Use Value: –55°C to +150°C operating range supports deployment in unheated cabinets or near motor drives; DO-41 fits legacy through-hole footprints. | Use Scenario: Charging bulk electrolytic capacitors after bridge rectification in constant-current LED drivers. IC Role / Device Role / Timing Role: Conducts during AC peaks to replenish capacitor charge; blocks reverse discharge path. Use Value: 5 µA max IR at 25°C prevents significant capacitor self-discharge between cycles; glass passivation resists flux residue corrosion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4007-T | Same VRRM, IF, IFSM; lead finish is matte tin (not pure tin), no JESD 201 whisker test data published | Identical electrical performance; may require process validation for high-reliability solder joints | Select 1N4007G-K when whisker resistance and J-STD-002 compliance are mandatory |
| STTH1R06 | 1 A, 600 V VRRM, 1.15 V VF, fast recovery (≤150 ns); TO-220AC package | Higher switching speed but lower voltage rating; unsuitable for 1000 V applications | Choose STTH1R06 only if circuit operates ≤600 V and requires reduced reverse recovery loss |
Compared with 1N4007-T and STTH1R06, the 1N4007G-K uniquely combines 1000 V capability, JESD 201 Class 1A whisker resistance, and pure tin leads-making it preferred for long-lifecycle industrial and outdoor-rated power supplies where reliability under thermal cycling and humidity is critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 1N4007G-K?
The 1N4007G-K has a VRRM of 1000 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2104). This rating defines the highest instantaneous reverse voltage the diode can block repeatedly without breakdown. It is the defining parameter distinguishing 1N4007G-K from lower-voltage variants like 1N4001G-K (50 V) or 1N4004G-K (400 V).
Is the 1N4007G-K RoHS and halogen-free compliant?
Yes, the 1N4007G-K is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The "G" in the part number denotes green (halogen-free) molding compound, and the "-K" suffix indicates tape-and-reel packaging with pure tin-plated leads meeting J-STD-002 solderability requirements.
What is the forward voltage (VF) of the 1N4007G-K at rated current?
The 1N4007G-K has a maximum forward voltage of 1.0 V at 1 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At higher temperatures or continuous DC, VF decreases slightly due to negative temperature coefficient of silicon diodes.
Does the 1N4007G-K have a specified junction-to-ambient thermal resistance (RθJA)?
Yes, the 1N4007G-K has a typical RθJA of 80°C/W, as listed in the Thermal Performance section of the datasheet. This value assumes standard JEDEC test conditions (single device on FR-4 board, 1-inch² copper pad). Actual thermal performance in end equipment depends on PCB layout, airflow, and adjacent heat sources.
What package type does the 1N4007G-K use, and how is polarity indicated?
The 1N4007G-K uses the DO-204AL (DO-41) axial-leaded package. Polarity is indicated by a distinct cathode band printed on the body - the banded end is the cathode terminal. The device weighs approximately 0.330 g and features pure tin-plated leads compliant with J-STD-002 for reliable solder wetting.
