Product details
Overview
STTH12002TV1 from STMicroelectronics is a dual center-tap ultrafast rectifier diode in ISOTOP package, rated for 2 × 60 A average forward current per diode, 200 V repetitive peak reverse voltage, and 35 ns typical reverse recovery time at 25°C. It serves as secondary-side high-power rectification in industrial welding inverters and DC power supplies where low conduction loss and fast switching are critical.
For engineers reviewing the STTH12002TV1 datasheet, STTH12002TV1 pinout, STTH12002TV1 application, or STTH12002TV1 equivalent, key selection criteria include verified dual-diode thermal coupling, junction-to-case thermal resistance of 0.76 °C/W per diode, and validated 700 A non-repetitive surge rating under 10 ms sinusoidal stress.
Technical Context
This dual-diode device integrates two independent ultrafast epitaxial planar junctions in a single insulated ISOTOP housing, enabling symmetrical center-tap rectification without external interconnection. Its 0.73 V typical forward voltage at 150°C/60 A and 35 ns trr support high-frequency operation up to 100 kHz in phase-shifted full-bridge converters.
The device features 2500 VRMS insulation between case and terminals, <45 pF junction capacitance at 30 V, and thermal coupling resistance of 0.1 °C/W between diodes-enabling accurate parallel thermal modeling when both diodes conduct simultaneously.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MBR100100CT | 100 A IF(AV) per diode, 100 V VRRM, TO-247AC package, no case insulation | Lower voltage rating limits use to ≤80 V DC bus; requires external isolation for safety-critical systems | Select only if system voltage ≤80 V and thermal management allows higher Rth(j-c) (1.2 °C/W) |
| Vishay VS-120CN02 | 120 A IF(AV), 200 V VRRM, SOT-227 package, 2500 VRMS insulation, but 55 ns trr (typ) | Slower recovery increases switching loss by ~30% in 50 kHz welder designs; larger footprint (42 × 32 mm) | Prefer when higher average current (120 A) is required and 55 ns trr is acceptable for lower-frequency operation |

FAQ
What is the maximum recommended case temperature for continuous operation?
The datasheet specifies IF(AV) = 60 A at Tc = 105°C, and Tj(max) = 150°C. With Rth(j-c) = 0.76 °C/W per diode, sustained case temperatures above 105°C require derating. For reliable 60 A operation, maintain Tc ≤ 105°C using forced-air cooling or heatsink interface resistance ≤ 0.25 °C/W.
Can STTH12002TV1 be used in parallel configurations across multiple units?
Yes-its matched VF and trr characteristics across diodes enable current sharing, but parallel operation requires identical PCB layout, thermal mounting, and external ballasting resistors (≤1 mΩ) to ensure <10% current imbalance. Do not parallel different date codes without verification.
Is the ISOTOP package RoHS-compliant and lead-free?
Yes. STTH12002TV1 conforms to RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound. The ISOTOP package meets JEDEC J-STD-020 moisture sensitivity level MSL3 and supports standard reflow profiles.
How does the 0.1 °C/W coupling resistance affect thermal design?
When both diodes conduct simultaneously, heat from one diode raises the junction temperature of the other. Use ∆Tj(diode1) = P1 × 0.76 + P2 × 0.1 to calculate cross-heating effect-critical for accurate derating in dual-leg rectifier topologies like center-tap or full-wave bridge variants.
