Product details

Overview

GPAS1001 from Taiwan Semiconductor is a 10A, 50V standard surface-mount rectifier diode in TO-263AB (D2PAK) package, featuring glass-passivated junction, 1.10V max forward voltage at 10A/25°C, 150A surge rating, and 4°C/W junction-to-case thermal resistance-used in DC-DC converters and switching-mode inverters.

For engineers reviewing the GPAS1001 datasheet, GPAS1001 pinout, GPAS1001 application, or GPAS1001 equivalent, key selection criteria include V_RRM = 50V, I_F = 10A continuous, I_FSM = 150A, T_J = –55°C to +150°C, and TO-263AB mechanical compatibility with high-power PCB layouts.

Technical Context

This single-die standard recovery rectifier operates with low conduction loss (V_F ≤ 1.10V @ 10A, 25°C) and high thermal efficiency (R_θJC = 4°C/W), enabling compact power stage designs in medium-frequency switching applications up to ~100 kHz.

Its glass-passivated junction ensures stable reverse leakage (I_R ≤ 5 µA @ 25°C, ≤100 µA @ 125°C) and robust surge tolerance (8.3 ms half-sine I_FSM = 150A), meeting JESD201 Class 1A whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum repetitive reverse blocking voltage; defines minimum system isolation margin for 50V DC bus applications.
I_F	10 A - Continuous forward current rating at T_C = 110°C; determines heatsink sizing in steady-state operation.
I_FSM	150 A - Non-repetitive peak surge current (8.3 ms); supports inrush and fault-current handling without bond-wire failure.
V_F (max)	1.10 V @ 10A, 25°C - Directly impacts conduction loss (P_cond ≈ 11 W at full load), influencing thermal design and efficiency.
R_θJC	4 °C/W - Junction-to-case thermal resistance; enables direct thermal interface to heatsink or copper pour for reliable 10A operation.
C_J	50 pF @ 1 MHz, 4V - Junction capacitance affects high-frequency switching noise and snubber design in hard-switched topologies.

Pinout & Package

Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with anode, cathode, and exposed drain tab (cathode-connected thermal pad).

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Input terminal for forward conduction path	Connected to input-side of bridge or boost inductor; must withstand full reverse voltage when off.
Cathode (Lead 2)	Output terminal for forward conduction path	Drives output capacitor or load; electrically tied to exposed thermal tab for low-inductance return path.
Exposed Tab (Cathode)	Thermal and electrical cathode extension	Provides primary heat dissipation path and reduces thermal resistance; requires soldered copper area ≥ 200 mm².

Key Features

Feature	Design Value
Glass-passivated junction	Enables stable long-term reliability under humidity and thermal cycling, eliminating need for conformal coating in industrial environments.
Low V_F (≤1.10 V)	Reduces conduction loss by ~15% vs. comparable 50V rectifiers, directly improving efficiency in 12–48V DC-DC stages.
High I_FSM/I_F ratio (15:1)	Supports transient overload conditions (e.g., motor startup, capacitor charging) without degradation or parametric shift.
Moisture sensitivity level 1	Eliminates bake requirement prior to reflow, enabling standard SMT assembly without process modification.

Equivalent & Alternatives

The following parts are listed as comparable options for similar standard rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-10E50S-M3/5BT	V_RRM = 50V, I_F = 10A, but R_θJC = 5.0°C/W and V_F = 1.15V (max)	Slightly higher conduction loss and thermal resistance; same TO-263AB footprint	Acceptable where 0.05V V_F margin and 1°C/W thermal penalty are tolerable
ON Semiconductor MUR1050CT	Dual common-cathode configuration (2×10A), V_F = 1.25V (max), TO-220AC package	Requires through-hole mounting and separate heatsink; not drop-in compatible	Only suitable if dual-diode topology and board real-estate allow TO-220 layout change

Compared with VS-10E50S-M3/5BT and MUR1050CT, GPAS1001 delivers lower conduction loss and superior thermal performance in the same surface-mount footprint-making it optimal for space-constrained, thermally demanding 10A rectification where efficiency and reliability are prioritized over dual-diode integration.

FAQ

What is the maximum junction temperature rating for GPAS1001?

The GPAS1001 has a maximum junction temperature (T_J) rating of +150°C, with operational range from –55°C to +150°C. This rating is validated under specified thermal conditions including R_θJC = 4°C/W and proper heatsinking. Derating curves in the GPAS1001 datasheet define safe operating current versus case temperature, ensuring reliability at elevated ambient conditions.

Is GPAS1001 RoHS and halogen-free compliant?

Yes, GPAS1001 is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound and matte tin-plated leads meet environmental and safety requirements for industrial and commercial electronics. Compliance documentation, including test reports and declarations of conformity, is available upon request from Taiwan Semiconductor and authorized distributors.

What is the forward voltage specification for GPAS1001 at 10A and 125°C?

The GPAS1001 datasheet specifies V_F only at 25°C (max 1.10V @ 10A). At 125°C, V_F decreases due to negative temperature coefficient of silicon PN junctions; typical values fall to ~0.95V. For precise thermal modeling, engineers should refer to the GPAS1001 forward characteristics curve (Fig.4) showing V_F vs. I_F across temperature.

Does GPAS1001 have a built-in thermal pad, and how should it be mounted?

Yes, GPAS1001 uses the TO-263AB (D2PAK) package with an exposed cathode thermal pad on the underside. It must be soldered to a minimum 200 mm² copper area on the PCB, preferably with thermal vias to internal ground planes. This pad is electrically connected to the cathode, so layout must ensure no unintended shorting to adjacent signals or power rails.

Can GPAS1001 replace GPAS1002 in a 100V design?

No-GPAS1001 is rated for 50V V_RRM, while GPAS1002 is rated for 100V. Substituting GPAS1001 in a 100V application risks catastrophic reverse breakdown and device failure. Always match the V_RRM rating to the peak reverse voltage seen in circuit operation, with ≥20% margin. GPAS1001 is only suitable for systems where peak reverse voltage remains ≤50V.
