Product details
Overview
STTH602CBY-TR from STMicroelectronics is an AEC-Q101 qualified dual center-tap ultrafast recovery diode in DPAK package, rated for 200 V repetitive peak reverse voltage, 3 A average forward current per diode (6 A total), and 14 ns typical reverse recovery time at 25 °C. It delivers low conduction losses (VF = 0.80 V typ. at 3 A, 25 °C) and high surge capability (60 A IFSM), enabling use in automotive-grade DC-DC converters and freewheeling circuits.
For engineers reviewing the STTH602CBY-TR datasheet, STTH602CBY-TR pinout, STTH602CBY-TR application, or STTH602CBY-TR equivalent, key selection criteria include dual-diode thermal coupling behavior, junction-to-case thermal resistance (5 °C/W per diode), AEC-Q101 qualification status, and 175 °C maximum junction temperature suitability for under-hood power electronics.
Technical Context
This dual-center-tap diode integrates two independent ultrafast recovery diodes sharing a common cathode terminal (K), configured for synchronous rectification or complementary freewheeling paths. Its 14 ns trr (typ.) and 4–5.5 A IRM at 125 °C support high-frequency switching up to 500 kHz in automotive SMPS.
The DPAK package enables direct thermal coupling to PCB copper planes, with Rth(j-c) = 5 °C/W per diode and Rth(c) = 1 °C/W coupling term when both diodes operate simultaneously-critical for accurate junction temperature prediction in dual-channel operation.
Key Specifications

| VRRM | 200 V - supports input stages of 12 V/24 V automotive DC-DC converters with 2× safety margin against load-dump transients |
| IF(AV) per diode | 3 A at Tc = 160 °C - defines continuous output current capability per leg in center-tap topology |
| trr (typ.) | 14 ns at IF = 1 A, dIF/dt = −100 A/μs - enables efficient operation at ≥300 kHz switching frequencies with minimal switching loss |
| VF (typ.) | 0.80 V at IF = 3 A, Tj = 25 °C - contributes to <1 W conduction loss per diode at nominal load |
| Tj(max) | 175 °C - meets under-hood thermal requirements for engine control units and ADAS power supplies |
| IFS M | 60 A (10 ms sinusoidal) - withstands cold-crank and jump-start surge events without failure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH602CW-TR | Same die, but in D2PAK (TO-263) package; Rth(j-c) = 3.5 °C/W per diode vs. 5 °C/W | Better thermal performance for >10 W dissipation; larger footprint and higher assembly cost | Select when junction temperature must stay <150 °C at >4.5 A per diode continuous current |
| VS-6EWH02FN-M3 | 100 V VRRM, 6 A IF(AV) per diode, 25 ns trr (typ.), TO-252 package | Limited to 12 V systems; higher trr increases switching loss at >200 kHz | Acceptable only for non-safety-critical 12 V DC-DC where AEC-Q101 is not mandated |
Compared with STTH602CBY-TR, STTH602CW-TR offers superior thermal resistance but requires PCB re-layout, while VS-6EWH02FN-M3 sacrifices voltage rating and speed for cost-making STTH602CBY-TR the optimal balance of automotive qualification, thermal capability, and space-constrained design fit.

FAQ
What is the maximum continuous forward current per diode at 155 °C case temperature?
The STTH602CBY-TR supports 6 A average forward current per diode at Tc = 155 °C, as specified in Table 2 of the datasheet (DocID023250 Rev 2). This rating assumes symmetrical thermal loading and proper PCB copper area (≥5 cm² per diode) to maintain junction temperature ≤175 °C.
Does the device require external snubbers in 200 kHz SMPS designs?
No external snubber is required in typical 200 kHz designs due to its 14 ns trr and low Qrr (<15 nC). Measured voltage overshoot remains below 10% of VRRM with standard layout practices; however, a 100 pF/10 Ω RC snubber is recommended if dIF/dt exceeds 300 A/μs in high-noise environments.
How is thermal coupling modeled when both diodes conduct simultaneously?
When both diodes operate concurrently, junction temperature rise is calculated as ΔTj(diode 1) = P₁ × 5 °C/W + P₂ × 1 °C/W, where P₁ and P₂ are individual diode power dissipations. This accounts for direct conduction path (5 °C/W) plus coupling through shared case (1 °C/W), per Table 3 in the datasheet.
Is the STTH602CBY-TR compatible with lead-free reflow profiles?
Yes-the DPAK package is RoHS-compliant and qualified for standard lead-free reflow (J-STD-020D, peak 260 °C, 20 s max). The epoxy meets UL94 V0 flammability rating, and the device is labeled ECOPACK®2, indicating halogen-free and green manufacturing compliance.
