Product details

Overview

GP1603H from Taiwan Semiconductor is an AEC-Q101-qualified 16A, 200V standard rectifier diode in TO-220AB package, featuring low forward voltage (1.1 V max at 8 A), high surge capability (150 A), and junction-to-case thermal resistance of 1.5 °C/W. It serves as a primary output rectifier in automotive DC-DC converters and industrial switching inverters.

For engineers reviewing the GP1603H datasheet, GP1603H pinout, GP1603H application, or GP1603H equivalent, key selection criteria include repetitive peak reverse voltage (200 V), forward current rating (16 A), thermal performance (R_θJC = 1.5 °C/W), AEC-Q101 qualification status, and TO-220AB mechanical compatibility with heatsink mounting.

Technical Context

This device is a single-die, unidirectional standard rectifier optimized for line-frequency and medium-frequency switching applications up to ~100 kHz. Its 200 V V_RRM rating targets 24–48 V system-level power conversion where moderate blocking voltage and high average current are required.

The GP1603H uses matte tin-plated leads compliant with J-STD-002, supports mounting torque up to 0.56 N·m, and meets JESD201 Class 2 whisker resistance. Its dual-die configuration is not applicable - GP1603H is a single-diode device per package, confirmed by marking code "GP1603" and absolute maximum ratings table.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum repetitive reverse voltage the diode blocks without breakdown; defines usable input/output voltage range in rectification stage
I_F	16 A - Continuous average forward current at case temperature ≤ 75 °C; sets minimum heatsink sizing requirement
I_FSM	150 A - Non-repetitive surge current (8.3 ms half-sine); determines robustness against startup/load-dump transients
V_F	1.1 V max @ 8 A, 25 °C - Forward voltage drop directly impacts conduction loss and thermal load in high-current paths
R_θJC	1.5 °C/W - Junction-to-case thermal resistance; enables direct calculation of junction temperature rise above heatsink temperature
T_J max	150 °C - Maximum allowable junction temperature; constrains derating curve and long-term reliability under thermal stress
I_R	10 µA max @ 200 V, 25 °C - Reverse leakage current; affects standby power loss and high-impedance sensing integrity

Pinout & Package

Package: TO-220AB - 3-lead through-hole package with isolated tab (cathode-connected tab), rated for >1.8 W continuous power dissipation when mounted on ≥10 cm² copper area or external heatsink.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Input current entry point	Connected to AC or switching node side; requires trace width ≥ 2 mm for 16 A continuous routing
Cathode (Lead 2)	Output current exit point	Electrically tied to metal tab; must be insulated from chassis unless system ground reference permits
Tab (Cathode)	Thermal & electrical cathode terminal	Primary heat path to heatsink; electrically identical to Lead 2; isolation voltage rating depends on mounting hardware

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive underhood applications including temperature cycling, mechanical shock, and humidity testing
Low V_F (1.1 V max)	Reduces conduction loss by ~15% vs. legacy 1.3 V rectifiers at 8 A, lowering thermal design margin requirements
R_θJC = 1.5 °C/W	Enables 10.7 °C junction rise per watt - supports compact heatsink designs in space-constrained enclosures
RoHS & halogen-free	Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally regulated production
150 A I_FSM	Withstands 6× rated current surge - accommodates inrush in 48 V battery-fed DC-DC modules without derating

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1602S	16 A, 200 V, VF = 1.15 V max @ 8 A, R_θJC = 1.7 °C/W, no AEC-Q101	Industrial-only use; lacks automotive qualification and has higher thermal resistance	Select when AEC-Q101 is not required and cost sensitivity outweighs thermal margin
ON Semi MUR1620CT	16 A, 200 V, dual common-cathode configuration, VF = 1.2 V max, R_θJC = 2.0 °C/W, no AEC-Q101	Requires PCB layout change due to dual-diode pinout; unsuitable for single-diode footprint	Choose only if dual-diode functionality is needed and automotive compliance is waived

Compared with STTH1602S and MUR1620CT, GP1603H delivers tighter thermal performance (1.5 vs. ≥1.7 °C/W) and certified automotive reliability - making it the sole option for AEC-Q101-compliant 200 V rectification where single-diode TO-220AB fit is mandatory.

FAQ

What is the AEC-Q101 qualification scope for GP1603H?

The GP1603H is fully AEC-Q101 qualified per Rev G test plan, covering temperature cycling, high-temperature operating life, unbiased highly accelerated stress test, and mechanical shock. This validation applies specifically to the GP1603H variant - not the base GP1603 - and confirms suitability for automotive underhood applications up to 125 °C ambient.

Does GP1603H have an isolated tab?

Yes, GP1603H uses a TO-220AB package with electrically isolated metal tab. The tab is internally connected to the cathode terminal (Lead 2), but the dielectric isolation between tab and leads meets ≥2500 V_RMS per UL 60950-1 - enabling safe mounting to grounded heatsinks without additional insulation when cathode is referenced to system ground.

What is the maximum recommended case temperature for continuous operation of GP1603H?

The GP1603H supports continuous operation up to 100 °C case temperature when derated per its forward current derating curve. At 100 °C case, the maximum allowable I_F is 12.8 A. Exceeding this requires active cooling or reduced load to maintain T_J ≤ 150 °C, as verified by R_θJC = 1.5 °C/W and thermal modeling.

How does GP1603H differ from GP1603 in terms of construction and reliability?

GP1603H differs from GP1603 solely in AEC-Q101 qualification and associated process controls - including wafer-level burn-in, enhanced lot traceability, and extended reliability testing. Electrically and thermally, GP1603H matches GP1603: identical V_RRM, I_F, V_F, and R_θJC. The "H" suffix denotes automotive-grade screening, not structural modification.

Can GP1603H replace GP1603 in existing designs without layout changes?

Yes, GP1603H is a direct form-fit-function replacement for GP1603 - same TO-220AB package, identical pinout, matching electrical and thermal specifications. No PCB or thermal interface changes are required; only documentation and supply chain updates are needed to reflect AEC-Q101 compliance for automotive programs.
