Product details
Overview
GPAS1004 from Taiwan Semiconductor is a 10A, 400V repetitive peak reverse voltage (VRRM) standard surface-mount silicon rectifier in TO-263AB (D2PAK) package, featuring glass-passivated junction, low forward voltage (VF ≤ 1.10 V at 10A), and high surge capability (IFSM = 150 A). It serves as a primary output rectifier in high-efficiency DC-DC converters.
For engineers reviewing the GPAS1004 datasheet, GPAS1004 pinout, GPAS1004 application, or GPAS1004 equivalent, key selection criteria include verified VRRM = 400 V, TJ max = 150°C, RθJC = 4°C/W, VF ≤ 1.10 V @ 10A, and IR ≤ 5 µA @ 25°C - all critical for thermal design and efficiency validation in switching power supplies.
Technical Context
The GPAS1004 operates as a single-die, unidirectional standard rectifier with no integrated control logic or recovery optimization. Its glass-passivated junction ensures stable performance under humid conditions (MSL Level 1), while its D2PAK thermally optimized copper tab enables direct heatsinking for continuous 10A conduction.
Electrical behavior follows classic PN-junction diode characteristics: forward conduction governed by VF vs. IF curve (typ. 0.95 V at 5A), reverse blocking validated up to 400 V with IR < 5 µA at 25°C and < 100 µA at 125°C, and junction capacitance of 50 pF at 4 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum non-repetitive reverse voltage the device blocks reliably without breakdown |
| IF | 10 A - continuous average forward current rating at case temperature ≤ 110°C |
| IFSM | 150 A - peak non-repetitive surge current (8.3 ms half-sine) the device withstands without failure |
| VF | ≤ 1.10 V @ 10A, 25°C - directly determines conduction loss (Pcond ≈ 11 W at full load) |
| RθJC | 4°C/W - thermal resistance from junction to case, enabling heatsink sizing for 10A operation |
| IR | ≤ 5 µA @ 400 V, 25°C - leakage level affecting standby power and high-impedance sensing accuracy |
| CJ | 50 pF @ 1 MHz, 4 V - impacts high-frequency switching noise and snubber design |
Pinout & Package
Package: TO-263AB (D2PAK) - surface-mount power package with exposed copper thermal pad (pin 3), 3-terminal configuration, UL 94V-0 molding compound, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry node | Connected to input/high-side potential; must route with low-inductance trace for EMI control |
| Cathode (Pin 2) | Forward current exit node | Connected to output/low-side return; common reference for output filter capacitor |
| Tab / Pin 3 | Thermal pad / Cathode connection | Electrically tied to cathode; requires soldered thermal land for heat dissipation and electrical continuity |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables MSL Level 1 handling and long-term reliability in humid environments without hermetic sealing |
| Low VF (≤1.10 V @ 10A) | Reduces conduction losses by ~15% versus typical 1.25 V rectifiers, improving system efficiency at full load |
| High IFSM (150 A) | Withstands cold-start surges and transient overloads in SMPS without degradation or latch-up |
| RθJC = 4°C/W | Supports 10A continuous operation with ≤40°C temperature rise above heatsink, simplifying thermal management |
| Halogen-free & RoHS compliant | Fulfills IPC-1752A material declaration requirements and meets EU environmental compliance mandates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R04DJF | VRRM = 400 V, IF = 10 A, VF = 1.05 V typ., but TO-220AC package (not surface-mount) | Requires through-hole PCB layout and manual assembly; higher RθJA than D2PAK | Select when legacy through-hole manufacturing or discrete heatsink mounting is required |
| ON Semi MUR1040 | VRRM = 400 V, IF = 10 A, VF = 1.25 V max, TO-220AC package, faster recovery (trr ≈ 50 ns) | Higher VF increases conduction loss; faster trr reduces switching noise but adds cost | Select only if fast recovery is prioritized over efficiency in noise-sensitive analog sections |
Compared with STTH10R04DJF and MUR1040, GPAS1004 provides surface-mount compatibility, lower VF than MUR1040, and better thermal performance than both due to its D2PAK package's 4°C/W RθJC - making it optimal for automated, high-density, thermally constrained power designs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for GPAS1004?
The GPAS1004 has a VRRM rating of 400 V, confirmed in the Absolute Maximum Ratings table across all official documentation versions (D2211). This value defines the highest reverse voltage the device can block repeatedly without avalanche breakdown under normal operating conditions, and is strictly validated per JEDEC JESD201 and JESD22-A115 standards.
Does GPAS1004 have a specified forward voltage (VF) at 10A, and what is its typical value?
Yes, GPAS1004 specifies VF ≤ 1.10 V at IF = 10 A and TJ = 25°C, per Electrical Specifications table. The typical VF is approximately 0.95 V under those conditions, measured using a 0.3 ms pulse test. This value directly impacts conduction loss calculation (Pcond ≈ IF × VF) in thermal and efficiency modeling for GPAS1004-based designs.
Is GPAS1004 compatible with lead-free reflow soldering processes?
Yes, GPAS1004 supports lead-free reflow soldering. Its matte tin-plated leads comply with J-STD-002 for solderability, and the device is rated MSL Level 1 (unlimited floor life), meaning it can be subjected to standard Pb-free reflow profiles (e.g., JEDEC J-STD-020, peak 260°C) without baking or special handling prior to assembly.
What is the thermal resistance from junction to case (RθJC) for GPAS1004, and how is it used in thermal design?
The GPAS1004 has a typical RθJC of 4°C/W, as published in the Thermal Performance section. This parameter is used to calculate junction temperature rise (ΔTJ = RθJC × Pdissipated) when the case temperature is known, enabling accurate heatsink sizing and derating analysis for GPAS1004 in continuous 10A operation.
How does the moisture sensitivity level (MSL) of GPAS1004 affect handling and storage?
GPAS1004 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no dry-packaging or baking before SMT assembly. This eliminates moisture-related popcorning risk during reflow and simplifies inventory management and production planning for GPAS1004 in high-volume manufacturing.
