Product details

Overview

STTH6002CW from STMicroelectronics is a dual-center-tab ultrafast recovery rectifier diode in TO-247 package, rated for 200 V repetitive peak reverse voltage, 60 A average forward current (per device), and 22 ns typical reverse recovery time. It delivers low conduction losses (VF = 0.75 V typ at 30 A, 150 °C) and high surge capability (330 A, 10 ms), enabling use in high-frequency switch-mode power supplies and DC–DC converters.

For engineers reviewing the STTH6002CW datasheet, STTH6002CW pinout, STTH6002CW application, or STTH6002CW equivalent, key selection factors include junction-to-case thermal resistance (0.8 °C/W total), dual-diode thermal coupling behavior, low forward voltage at elevated temperature, and validated performance under high dIF/dt (200 A/µs) conditions.

Technical Context

This dual-diode rectifier integrates two independent ultrafast switching diodes sharing a common cathode tab and center-mounted case terminal. Its design targets high-efficiency, high-frequency operation where low trr and minimal QRR reduce switching losses in hard-switched topologies.

Thermal management relies on conduction cooling via the TO-247 metal tab; junction-to-case resistance is 0.8 °C/W total (1.2 °C/W per diode), with coupling resistance of 0.4 °C/W between diodes-critical for accurate thermal derating when both diodes conduct simultaneously.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - supports input stages up to 200 V DC or rectified AC without breakdown
I_F(AV)	60 A (per device, T_c = 125 °C) - enables high-power output in compact SMPS designs
t_rr (typ)	22 ns - minimizes switching loss and EMI generation in >100 kHz converters
V_F (typ)	0.75 V @ 30 A, 150 °C - reduces conduction loss and thermal stress at full load and high ambient
I_FSM	330 A (10 ms, sinusoidal) - withstands startup surges and transient overloads without failure
T_j(max)	175 °C - allows operation in thermally constrained industrial or automotive under-hood environments
R_th(j-c)	0.8 °C/W (total) - defines maximum allowable power dissipation for given heatsink interface temperature

Pinout & Package

STTH6002CW is housed in a TO-247 package with three terminals: two anodes (A1, A2) and one shared cathode (K) mounted on the center metal tab. The case serves as the cathode connection and primary thermal path.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first diode leg; electrically isolated from A2 and K
A2	Anode 2	Input terminal for second diode leg; independent conduction path from A1
K (Tab)	Common Cathode	Output node for both diodes; mechanical mounting surface and primary thermal interface

Key Features

Applications

Server Power Supply Rectification

Industrial DC–DC Converter Output Stage

Use Scenario: High-density 48 V input, 12 V/54 A output DC–DC brick with synchronous rectification assist.

IC Role / Device Role / Timing Role: Dual-anode ultrafast diode provides freewheeling path and polarity protection during MOSFET dead-time.

Use Value: 22 ns t_rr limits reverse recovery charge (Q_RR) to <15 nC, reducing cross-conduction loss and EMI filtering burden.

Use Scenario: 24 V input, 5 V/30 A isolated flyback converter for PLC I/O modules.

IC Role / Device Role / Timing Role: Center-tab dual diode serves as synchronous rectifier clamp and output polarity guard.

Use Value: 0.75 V V_F at 150 °C cuts conduction loss by 0.45 W per diode vs. legacy 1.05 V parts, easing thermal design.

Solar Microinverter DC Link Clamp

Automotive On-Board Charger (OBC) Input Rectifier

Use Scenario: 600 V DC link clamping in single-phase transformerless microinverter with H-bridge topology.

IC Role / Device Role / Timing Role: Dual-diode configuration absorbs reverse recovery energy during bridge commutation.

Use Value: 175 °C T_j(max) and 330 A I_FSM ensure reliability under partial shading-induced transients and thermal cycling.

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
IXYS MUR6020CT	Same V_RRM (200 V), higher I_F(AV) (60 A), but slower t_rr (35 ns typ) and higher V_F (0.92 V @ 30 A)	Acceptable in lower-frequency (<100 kHz) SMPS where EMI margin exists	Prefer STTH6002CW where t_rr < 25 ns is required to meet CISPR-22 Class B EMI limits
Vishay VS-60CPH02	TO-247 dual diode, identical V_RRM and I_F(AV), but t_rr = 30 ns and R_th(j-c) = 0.95 °C/W	Suitable for space-constrained industrial supplies with moderate thermal budgets	Choose STTH6002CW when thermal resistance ≤0.85 °C/W and t_rr ≤25 ns are mandatory for target efficiency

Compared with MUR6020CT and VS-60CPH02, STTH6002CW offers the lowest combined t_rr/V_F trade-off and best thermal resistance-making it optimal for high-frequency, high-efficiency, and thermally aggressive applications such as telecom rectifiers and server VRMs.

FAQ

What is the thermal coupling behavior between the two diodes in STTH6002CW?

The datasheet specifies a coupling thermal resistance R_th(c) of 0.4 °C/W between diodes in TO-247. When both diodes conduct simultaneously, heat from one diode raises the junction temperature of the other-requiring derating using ∆T_j(diode 1) = P(diode 1) × R_th(j-c) + P(diode 2) × R_th(c). This interaction must be modeled in thermal simulations.

Can STTH6002CW replace a single-diode TO-247 rectifier in existing layouts?

No-it is not a drop-in replacement. STTH6002CW has three terminals (A1, A2, K) versus two (A, K) in single-diode parts. PCB footprint, gate drive isolation, and thermal pad routing must accommodate dual-anode separation and shared cathode tab. Layout revision is required.

How does reverse recovery performance change with temperature and dIF/dt?

At 125 °C, t_rr increases to 27 ns max (vs. 22 ns typ at 25 °C), and IRM rises to 9.5 A. With dIF/dt = 200 A/µs, t_rr remains stable at ~22 ns, but Q_RR grows from 12 nC (25 °C) to 28 nC (125 °C)-a critical factor for snubber sizing in high-temperature operation.

Is STTH6002CW suitable for synchronous rectification circuits?

It is not a synchronous rectifier IC but can serve as a freewheeling or clamp diode alongside MOSFETs in synchronous topologies. Its ultrafast t_rr prevents shoot-through during MOSFET turn-on, and low V_F minimizes conduction loss when body diode conduction occurs during dead-time.
