Product details
Overview
GP1002 from Taiwan Semiconductor is a 10A, 100V standard rectifier diode in TO-220AB package, featuring low forward voltage (1.1V @ 5A), high surge capability (125A), and AEC-Q101 qualification option. It serves as a primary output rectifier in DC-DC converters and switching inverters where efficiency and thermal robustness are critical.
For engineers reviewing the GP1002 datasheet, GP1002 pinout, GP1002 application, or GP1002 equivalent, key selection criteria include repetitive peak reverse voltage (100V), junction-to-case thermal resistance (3°C/W), forward voltage consistency across temperature, and compatibility with high-reliability automotive power supplies.
Technical Context
The GP1002 uses dual-die construction in a single TO-220AB case, enabling symmetrical current sharing and improved thermal distribution. Its silicon PN junction delivers stable reverse leakage (≤5 µA @ 25°C, ≤200 µA @ 125°C) and low junction capacitance (30 pF @ 4V).
Designed for hard-switched topologies, it supports 8.3ms non-repetitive surge currents up to 125A and operates continuously at junction temperatures from –55°C to +150°C, with derating starting at 75°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback or forward converter secondary side |
| IF | 10 A - Continuous average forward current; determines heatsink sizing for steady-state conduction loss |
| IFSM | 125 A - Peak non-repetitive surge current; withstands inrush and fault transients without failure |
| VF | 1.1 V max @ 5A, 25°C - Directly impacts conduction loss and system efficiency at nominal load |
| RθJC | 3 °C/W - Enables accurate thermal modeling between junction and heatsink mounting surface |
| CJ | 30 pF @ 1 MHz, 4 V - Influences high-frequency switching noise and snubber design in SMPS |
Pinout & Package
TO-220AB package with three terminals: Anode (pin 1), Cathode (pin 2), and metal tab (pin 3, electrically connected to cathode). Matte tin-plated leads meet J-STD-002 solderability; mounting torque ≤0.56 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Input current entry point | Connected to transformer secondary or switch node; polarity must match layout marking |
| Pin 2 (Cathode) | Output current exit point | Common return path for rectified output; tied to metal tab for thermal conduction |
| Metal tab (Cathode) | Thermal and electrical cathode extension | Provides direct thermal interface to heatsink; requires insulating washer if isolated mounting needed |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified variant available (GP1002H) | Validated for automotive under-hood applications including engine control and ADAS power supplies |
| Low VF (1.1 V max) | Reduces conduction loss by ~15% vs. legacy 1.3 V rectifiers at 5A, improving 12V–48V DC-DC efficiency |
| Junction-to-case RθJC = 3°C/W | Enables compact heatsink design-e.g., 15 cm² aluminum finned sink achieves <90°C junction rise at 10A |
| Dual-die configuration | Improves current sharing uniformity and thermal stress distribution under asymmetric PCB layout conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R06DJF | 600V VRRM, 1.15V VF, TO-220AC package (single cathode tab) | Higher voltage rating but higher VF; not AEC-Q101 qualified | Preferred for 400V+ systems where GP1002's 100V rating is insufficient |
| ON Semi MUR1020CT | 200V VRRM, 1.2V VF, dual common-cathode configuration, same TO-220AB footprint | Higher voltage margin and identical pinout, but no AEC-Q101 option | Drop-in replacement for GP1002 in non-automotive 200V designs requiring same mechanical fit |
Compared with STTH10R06DJF and MUR1020CT, GP1002 offers optimal balance of low VF, automotive qualification, and precise 100V rating-making it ideal for cost-sensitive, thermally constrained 12V–48V automotive and industrial converters where overvoltage margin is tightly managed.

FAQ
What is the maximum junction temperature rating for GP1002?
The GP1002 has a maximum junction temperature (TJMAX) of +150°C, verified per JEDEC JESD22-A108. This allows operation in high-ambient environments such as engine compartments or enclosed industrial cabinets. Derating begins at 75°C case temperature, and thermal design must maintain junction temperature below 150°C under worst-case load and ambient conditions. The GP1002 datasheet specifies this limit across all variants including GP1002H.
Is GP1002 pin-compatible with other TO-220AB rectifiers like MUR1020CT?
Yes, GP1002 uses the standard TO-220AB outline with anode (pin 1), cathode (pin 2), and cathode-connected metal tab-identical pinout to MUR1020CT and STTH10R06DJF. However, GP1002's dual-die internal structure differs from single-die alternatives, so thermal and electrical behavior under asymmetrical loads may vary. Always verify layout clearance and heatsink mounting per GP1002 mechanical drawings.
Does GP1002 support automotive-grade reliability requirements?
Yes-the GP1002H variant is fully AEC-Q101 qualified, including stress testing for temperature cycling, humidity bias, and mechanical shock. Standard GP1002 is not AEC-Q101 certified, but shares identical die and packaging process. For automotive applications, only GP1002H should be specified; its qualification covers the full 100V rating, 10A current, and 150°C junction operation required by ISO/TS 16949-compliant supply chains.
What is the typical forward voltage drop of GP1002 at rated current?
The GP1002 exhibits a maximum forward voltage (VF) of 1.1 V at 5A and 25°C, per the datasheet's electrical specifications. At full 10A DC current and 125°C junction temperature, VF rises to approximately 1.25 V. This low VF directly reduces conduction losses-e.g., 12.5 W at 10A versus 15.5 W for a 1.3 V diode-improving thermal margin in compact power designs.
How does GP1002's junction capacitance affect high-frequency switching performance?
GP1002 has a typical junction capacitance (CJ) of 30 pF at 4V reverse bias and 1 MHz, measured per JEDEC JESD24-11. This low capacitance minimizes reverse recovery charge (Qrr) and associated switching losses in 100–500 kHz SMPS topologies. It also reduces EMI generation during turn-off transitions, easing compliance with CISPR-22 Class B limits in industrial and automotive power supplies using GP1002.
