Product details
Overview
STTH8R02DDJFY-TR from STMicroelectronics is an AEC-Q101-qualified dual ultrafast rectifier in PowerFLAT™ 5x6 Dual Island package, rated for 200 V repetitive peak reverse voltage and 4 A average forward current per diode, with typical forward voltage of 0.71 V at 150 °C and 16 ns reverse recovery time - deployed in automotive switching-mode base drive and free-wheeling circuits.
For engineers reviewing the STTH8R02DDJFY-TR datasheet, STTH8R02DDJFY-TR pinout, STTH8R02DDJFY-TR application, or STTH8R02DDJFY-TR equivalent, key selection criteria include dual-diode thermal coupling, wettable flanks for automated optical inspection, low conduction loss (P = 0.72 × IF(AV) + 0.040 × IF²(RMS)), AEC-Q101 qualification, and PPAP capability for automotive power systems.
Technical Context
The STTH8R02DDJFY-TR integrates two independent ultrafast silicon rectifiers in a single thermally coupled PowerFLAT™ 5x6 Dual Island package, enabling shared heatsinking while maintaining electrical isolation between diodes. Each diode exhibits 23 ns typical reverse recovery time at 1 A / −50 A/µs and 15 ns at −100 A/µs, with negligible switching losses due to low Qrr (65 nC) and IRM (6.0 A).
It operates across −40 °C to +175 °C junction temperature range, supported by Rth(j-c) = 5 °C/W per diode and total thermal coupling of 3 °C/W. The device uses planar epitaxial technology optimized for high dI/dt immunity and stable VF drift over temperature - critical for automotive transistor snubbing and synchronous rectification assist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - supports 12 V/24 V automotive bus-derived DC-DC stages with 2× safety margin against load dump transients |
| IF(AV) | 2 × 4 A - enables dual-path 8 A total average forward current handling with shared thermal path |
| VF (typ.) | 0.71 V @ 150 °C, 4 A - reduces conduction loss to ≤0.72×IF(AV) + 0.040×IF(RMS)² in high-temp operation |
| trr (typ.) | 16 ns - minimizes switching loss and EMI in >100 kHz SMPS base-drive and freewheeling applications |
| Tj(max) | +175 °C - allows direct mounting on engine-control PCBs without external heatsink in space-constrained modules |
| Rth(j-c) | 5 °C/W per diode - enables 4 W dissipation per diode at ΔT = 20 °C case-to-junction rise |
| Qrr | 65 nC - limits reverse recovery energy loss during hard-switching transitions in motor gate drive circuits |
Pinout & Package
STTH8R02DDJFY-TR uses the PowerFLAT™ 5x6 Dual Island package (95 mg), featuring two isolated copper pads (A1/K1 and A2/K2) for cathode/anode connections per diode, with wettable flanks for automated optical inspection. Package dimensions: 6.0 × 5.2 × 1.0 mm (L × W × H), with 1.27 mm pitch between centerlines of dual pads.
| Pin/Terminal | Circuit Role | Design Meaning |

IC Role / Device Role / Timing Role: Dual-channel rectifier supporting bidirectional PWM control with independent anode routing for H-bridge symmetry. Use Value: Maintains <0.8 V forward drop at 150 °C ambient, reducing thermal derating and enabling smaller heatsinks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R02DJF-TR | Same die, but single-island PowerFLAT™ 5x6 package (no dual pad separation); Rth(j-c) = 4.5 °C/W total | Lacks independent anode/cathode isolation; unsuitable where circuit separation or differential layout is required | Select when thermal performance is prioritized over circuit independence and footprint flexibility |
| ON Semiconductor MUR820CT | TO-220AB package, 8 A total IF(AV), 200 V VRRM, trr = 35 ns, no AEC-Q101 qualification | Requires mechanical mounting and external heatsink; not PPAP-capable or automotive-grade qualified | Select only for non-automotive industrial prototypes where cost outweighs qualification and miniaturization needs |
Compared with STTH8R02DDJFY-TR, the STTH8R02DJF-TR offers better thermal resistance but forfeits layout isolation, while the MUR820CT provides higher current rating at the expense of qualification, size, and switching speed - making the STTH8R02DDJFY-TR optimal for space-constrained, PPAP-driven automotive power stages.

FAQ
What is the maximum junction temperature and how is it validated?
The STTH8R02DDJFY-TR has a maximum operating junction temperature of +175 °C, verified per AEC-Q101 stress test conditions including high-temperature operating life (HTOL) at 175 °C for 1000 hours and temperature cycling from −40 °C to +150 °C for 1000 cycles. Thermal runaway is prevented by satisfying (dPtot/dTj) < (1/Rth(j-a)) under specified heatsinking conditions.
Does this part support automatic optical inspection (AOI)?
Yes - the PowerFLAT™ 5x6 Dual Island package features wettable flanks with controlled side-wall plating depth and geometry compliant with IPC-J-STD-020, enabling reliable solder joint inspection using standard AOI systems without requiring X-ray verification.
How does the dual-island structure affect thermal performance?
The dual-island design provides two electrically isolated copper pads with shared thermal substrate, achieving 5 °C/W Rth(j-c) per diode and 3 °C/W total coupling. This allows simultaneous 4 A operation per diode while limiting total junction rise to ≤20 °C above case at 8 W combined dissipation - verified via transient thermal impedance curves in Figure 9.
Is PPAP documentation available for this part?
Yes - STMicroelectronics provides full PPAP Level 3 documentation for STTH8R02DDJFY-TR, including part submission warrant, design records, process flow diagrams, control plans, measurement system analysis (MSA), and initial process studies (SPC), all accessible through ST's authorized distributor portal upon customer request and NDA.
