Product details
Overview
STTH8L02DDJFY-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, 4 A average forward current per diode, and 20 ns typical reverse recovery time at 125 °C. It serves as a freewheeling diode in automotive power supplies and switching-mode transistor base drive circuits.
For engineers reviewing the STTH8L02DDJFY-TR datasheet, STTH8L02DDJFY-TR pinout, STTH8L02DDJFY-TR application, or STTH8L02DDJFY-TR equivalent, key selection criteria include low conduction loss (VF = 0.7 V typ. @ 150 °C), high junction temperature capability (Tj(max) = 175 °C), wettable flanks for automated optical inspection, and dual-diode thermal isolation in a surface-mount package.
Technical Context
This dual-island ultrafast rectifier integrates two independent, thermally isolated diodes in a single PowerFLAT™ 5x6 package with separate anode (A1, A2) and cathode (K1, K2) terminals. Each diode exhibits negligible switching losses due to trr = 20 ns (typ.) at IF = 4 A, dIF/dt = –200 A/µs, VR = 160 V, Tj = 125 °C.
Its low VF (0.7 V typ. @ 150 °C, 4 A) and high thermal robustness (Rth(j–c) = 2.0 °C/W total) enable efficient operation in space-constrained automotive power stages where conduction loss minimization and junction temperature stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands up to 200 V reverse voltage without breakdown in automotive transients. |
| IF(AV) per diode | 4 A - Sustains continuous forward current up to 4 A per diode at Tc = 160 °C. |
| trr (typ.) | 20 ns - Enables high-frequency switching (>1 MHz) with minimal reverse recovery energy loss. |
| VF (typ.) | 0.7 V @ 150 °C, 4 A - Reduces conduction loss to ~2.8 W per diode under full load at elevated temperature. |
| Tj(max) | 175 °C - Supports operation in under-hood environments without derating in most automotive duty cycles. |
| Rth(j–c) total | 2.0 °C/W - Allows 40 W total dissipation (20 W per diode) with ≤80 °C case-to-junction rise at steady state. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8L02DJY-TR | Same die, but single-island PowerFLAT™ 5x6 package - shared thermal path between diodes. | Lacks thermal isolation; unsuitable for asymmetric load sharing or independent channel thermal design. | Select when cost priority outweighs thermal independence and both diodes operate at matched load/temperature. |
| VS-8EWH02FN-M3/45 | 100 V rating, 8 A IF(AV), TO-252AA package - higher current, lower voltage, larger footprint. | Not AEC-Q101 qualified; lacks wettable flanks and PPAP support; requires manual inspection. | Choose only for non-automotive industrial designs requiring higher IF(AV) and accepting larger board area and qualification gap. |
Compared with STTH8L02DJY-TR, the STTH8L02DDJFY-TR provides true dual-channel thermal isolation critical for automotive redundancy; versus VS-8EWH02FN-M3/45, it delivers AEC-Q101 compliance, wettable flanks, and smaller footprint-essential for modern ADAS and EPS modules.

FAQ
What does "Dual Island" mean in the STTH8L02DDJFY-TR package?
"Dual Island" refers to physically and thermally isolated anode-cathode pairs (A1/K1 and A2/K2) mounted on separate copper pads within the same PowerFLAT™ 5x6 footprint. This eliminates thermal crosstalk, allowing independent thermal management and enabling asymmetric loading-critical for automotive fault-tolerant designs where one diode may handle higher stress than the other.
Is STTH8L02DDJFY-TR suitable for synchronous rectification?
No-it is a silicon PN junction ultrafast rectifier, not a MOSFET-based synchronous rectifier. While its 20 ns trr supports high-frequency operation, it lacks gate control and cannot replace a controlled switch. It is optimized for freewheeling and clamping roles where unidirectional conduction and low VF are prioritized over active switching.
How does the wettable flank feature improve manufacturing yield?
The wettable flanks provide solderable side-wall plating on all four edges of the PowerFLAT™ package, enabling automated optical inspection (AOI) to verify solder fillet formation and joint integrity. This eliminates reliance on X-ray for hidden-joint verification, reduces false call rates, and supports zero-defect goals required for automotive Tier-1 production lines.
Can STTH8L02DDJFY-TR replace a single-diode part like STTH8L02D-Y?
Yes-but only if both diodes are used identically and thermally coupled. The STTH8L02DDJFY-TR contains two independent diodes; using only one wastes half the package capability and forfeits the thermal isolation benefit. For single-diode applications, STTH8L02DJY-TR (same die, single-island) is the direct replacement with identical electrical specs and lower cost.
