Product details

Overview

STTH1602CGY-TR from STMicroelectronics is an AEC-Q101-qualified dual center-tap ultrafast rectifier diode in D²PAK package, rated for 2 × 8 A average forward current per diode, 200 V repetitive peak reverse voltage, and 21 ns typical reverse recovery time. It operates up to 175 °C junction temperature and is engineered for low-loss freewheeling and polarity protection in automotive DC–DC converters.

For engineers reviewing the STTH1602CGY-TR datasheet, STTH1602CGY-TR pinout, STTH1602CGY-TR application, or STTH1602CGY-TR equivalent, key selection criteria include its dual-diode thermal coupling behavior (R_th(c) = 0.5 °C/W), low 0.78 V typical forward voltage at 150 °C/8 A, and guaranteed V_RRM stability across –40 to +175 °C.

Technical Context

This dual-center-tap configuration integrates two independent ultrafast switching diodes sharing a common cathode terminal (K), enabling synchronous rectification or complementary freewheeling paths in half-bridge or full-wave topologies. Its 21 ns t_rr and soft recovery (softness factor >1) minimize switching noise and EMI in high-frequency (>100 kHz) automotive power stages.

The D²PAK package provides low thermal resistance - 2.7 °C/W junction-to-case per diode and 1.6 °C/W per device - with direct copper tab mounting for conduction cooling. Thermal coupling between diodes is modeled via R_th(c), requiring simultaneous power dissipation calculation: ΔT_j(diode1) = P_diode1 × 2.7 + P_diode2 × 0.5.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - supports 12 V/24 V automotive systems with ≥2× safety margin against load-dump transients
I_F(AV)	2 × 8 A - enables 16 A total continuous output in center-tap configurations with derating at T_C > 140 °C
t_rr (typ.)	21 ns - reduces turn-off losses and allows operation up to 500 kHz in SMPS without excessive di/dt-induced ringing
V_F (typ.)	0.78 V @ 150 °C / 8 A - lowers conduction loss to ~6.2 W per diode at full rated current
T_j(max)	175 °C - meets under-hood thermal requirements for engine control units and ADAS power supplies
I_R (max)	60 µA @ 125 °C - ensures minimal leakage in high-temperature reverse-biased standby modes
R_th(j-c)	2.7 °C/W per diode - requires ≥25 mm² copper pad for ≤40 K rise at 8 A continuous

Pinout & Package

D²PAK (TO-263-3L) package with isolated copper tab (cathode-connected), surface-mount footprint, and single-sided thermal interface. Dimensions: 10.55 × 9.35 × 4.60 mm (L × W × H); weight: 1.48 g.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first diode path; connects to high-side switch node in center-tap buck or flyback
A2	Anode 2	Input terminal for second diode path; used for complementary phase or redundant path routing
K	Common Cathode	Shared output node; must be thermally anchored to PCB ground plane for heat extraction and EMI control

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive use including temperature cycling, humidity testing, and mechanical shock per JESD22 standards
Ultrafast recovery (21 ns)	Enables high-frequency switching without snubber networks in 12 V/48 V DC–DC modules
Low V_F drift with temperature	0.78 V @ 150 °C (vs. 1.10 V @ 25 °C) minimizes thermal runaway risk in parallel operation
Guaranteed V_RRM over full T_j	200 V holds from –40 to +175 °C - eliminates derating calculations for transient voltage margins
Dual-diode thermal coupling model	R_th(c) = 0.5 °C/W allows accurate junction temperature prediction when both diodes conduct simultaneously

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast dual-diode rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1602C-TR	Same die, D²PAK package but non-automotive grade (no AEC-Q101 qualification); identical electrical specs	Lacks PPAP documentation and extended temperature validation; unsuitable for Tier-1 automotive programs	Select only for industrial or consumer-grade 12 V/24 V SMPS where AEC-Q101 is not mandated
IXYS MUR1620CT	200 V, 16 A dual diode but slower t_rr (35 ns typ.), higher V_F (0.95 V @ 150 °C), no AEC-Q101	Higher conduction and switching losses; requires larger heatsink and snubber components	Acceptable for cost-sensitive non-automotive applications where efficiency >90% is not required

Compared with STTH1602C-TR and MUR1620CT, STTH1602CGY-TR uniquely delivers AEC-Q101 compliance, 21 ns t_rr, and guaranteed 200 V V_RRM across –40 to +175 °C - making it the only choice for PPAP-submittable automotive power designs demanding low EMI and thermal robustness.

FAQ

Is STTH1602CGY-TR pin-compatible with STTH1602C-Y?

Yes - STTH1602CGY-TR and STTH1602C-Y share identical D²PAK pinout (A1, A2, K), mechanical dimensions, and electrical specifications. The "GY" suffix denotes tape-and-reel packaging (1000 pcs) and automotive-grade marking; the base die and layout are functionally identical.

What is the maximum allowable case temperature for continuous operation?

The datasheet specifies I_F(AV) = 16 A per device at T_C = 140 °C. Exceeding 140 °C requires linear derating: at T_C = 150 °C, max I_F(AV) drops to 12.8 A; at 160 °C, it falls to 9.6 A. Thermal design must maintain T_C ≤ 140 °C for full-rated current.

Does STTH1602CGY-TR require a heatsink in typical automotive applications?

A minimum 25 mm² copper pour under the tab is mandatory. For 8 A per diode continuous conduction at 150 °C ambient, a 20 cm² external heatsink lowers T_j by ~18 K. Without added heatsinking, T_j reaches 162 °C at 12 A total - within spec but leaves <13 °C margin to 175 °C limit.

Can STTH1602CGY-TR be used in non-automotive applications?

Yes - its 200 V V_RRM, 21 ns t_rr, and 175 °C rating make it suitable for industrial SMPS, telecom power supplies, and medical equipment where high reliability and low EMI are critical. However, AEC-Q101 test data does not confer qualification outside automotive use cases.
