Product details

Overview

GP1601 from Taiwan Semiconductor is a 16A, 50V standard rectifier diode in TO-220AB package with dual-die configuration, 150A surge rating, 1.1V max forward voltage at 8A/25°C, and AEC-Q101 qualification available. It serves as primary AC/DC rectification element in high-efficiency power supplies for industrial converters.

For engineers reviewing the GP1601 datasheet, GP1601 pinout, GP1601 application, or GP1601 equivalent, key selection criteria include repetitive peak reverse voltage (50V), thermal resistance (1.5°C/W), junction temperature range (–55°C to +150°C), RoHS/halogen-free compliance, and TO-220AB mechanical mounting requirements.

Technical Context

The GP1601 operates as a single-phase, standard recovery rectifier with dual-die construction enabling parallel current handling within one TO-220AB housing. Its 1.1V VF max at 8A/25°C and 10µA IR max at 25°C support low conduction loss in continuous-duty DC-DC stages.

Thermal performance is defined by R_θJC = 1.5°C/W and T_J rating up to +150°C, allowing stable operation under forced-air or heatsink-mounted conditions in switching mode inverters and SMPS front-end rectification.

Key Specifications

V_RRM	50 V - Maximum repetitive reverse blocking voltage; defines safe AC input voltage ceiling in bridge or half-wave rectifiers
I_F	16 A - Continuous average forward current; sets minimum heatsink sizing for steady-state 12–24V output converters
I_FSM	150 A - Non-repetitive surge rating (8.3ms sine); supports inrush tolerance during cold-start of offline SMPS
V_F max	1.1 V @ 8A, 25°C - Low conduction loss enables >92% efficiency in 12V/10A output designs
R_θJC	1.5 °C/W - Enables direct heatsink mounting without thermal interface pads for ≤3W dissipation at full load
Junction Temp	–55°C to +150°C - Supports operation in automotive under-hood and industrial ambient environments

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1605D	16A, 50V, TO-220AC package, VF = 1.15V max @ 8A, R_θJC = 1.7°C/W	No AEC-Q101 variant; slightly higher thermal resistance	Preferred where STMicroelectronics sourcing is mandated; verify heatsink interface due to TO-220AC tab isolation
ON Semi MUR1620CT	16A, 200V, dual common-cathode, VF = 1.2V max @ 8A, R_θJC = 1.8°C/W	Higher V_RRM but lower surge rating (100A) and no AEC-Q101 option	Use only if 200V blocking is required; not suitable for 50V-limited designs without derating

Compared with STTH1605D and MUR1620CT, the GP1601 offers tighter V_RRM matching for 50V systems, lower R_θJC, and optional AEC-Q101 qualification-making it optimal for cost-sensitive, thermally constrained, or automotive-qualified 50V rectification.

FAQ

What is the maximum junction temperature rating for the GP1601?

The GP1601 has a maximum junction temperature (T_J) rating of +150°C, with an operational range from –55°C to +150°C. This rating enables reliable use in enclosed industrial enclosures and automotive under-hood environments when mounted on an appropriately sized heatsink. The GP1601's 1.5°C/W junction-to-case thermal resistance supports thermal design margins up to 3W dissipation at full 16A load.

Is the GP1601 pin-compatible with other TO-220AB rectifiers like the 1N5408?

The GP1601 uses the standard TO-220AB outline with Anode–Cathode–Tab pinout, making it mechanically compatible with legacy TO-220AB rectifiers such as the 1N5408. However, the GP1601 offers higher current (16A vs. 3A), lower VF (1.1V vs. ~1.2V), and dual-die construction - requiring verification of PCB copper area and heatsinking for the increased power handling. The GP1601 is not a direct electrical drop-in without thermal redesign.

Does the GP1601 have AEC-Q101 qualification?

Yes, the GP1601 is available in an AEC-Q101 qualified version designated GP1601H. This variant undergoes stress testing per AEC-Q101 Rev D for automotive applications including engine control units and body electronics. Standard GP1601 parts are not AEC-Q101 qualified; only GP1601H carries the qualification. Both share identical electrical and thermal specs.

What is the forward voltage specification for the GP1601 at elevated temperature?

The GP1601 datasheet specifies forward voltage only at 25°C (VF ≤ 1.1V @ 8A). No typ/max values are provided at elevated temperatures. However, typical silicon diode VF decreases ~2mV/°C, so at 125°C junction temperature, VF is expected to be ~0.9V–0.95V at 8A. For precise thermal modeling, users should consult GP1601 curve Fig.4 (Typical Forward Characteristics) in the official TSC datasheet.

How does the dual-die configuration of the GP1601 affect its performance?

The GP1601 integrates two identical rectifier dies in parallel within one TO-220AB package, improving current sharing, thermal symmetry, and surge robustness compared to single-die alternatives. This configuration reduces effective series resistance and distributes heat across both dies, contributing to the 1.5°C/W R_θJC and 150A I_FSM rating. The dual-die layout is internal and does not change external pinout or mounting.
