STMicroelectronics STTH10002TV2

Overview

STTH10002TV2 from STMicroelectronics is a dual ultrafast recovery silicon rectifier diode in ISOTOP package, rated for 2 × 50 A average forward current per diode, 200 V repetitive peak reverse voltage, and 30 ns typical reverse recovery time at 125 °C. It delivers low conduction loss (VF = 0.72 V typ. at 50 A, 150 °C) and high surge capability (750 A, 10 ms), designed for secondary-side rectification in high-power industrial welding equipment.

For engineers reviewing the STTH10002TV2 datasheet, STTH10002TV2 pinout, STTH10002TV2 application, or STTH10002TV2 equivalent, key selection criteria include dual-diode thermal coupling behavior, insulated case rating (2500 V_rms), junction-to-case thermal resistance (0.55 °C/W total), and dIF/dt-dependent recovery performance under high-frequency switching conditions.

Technical Context

The STTH10002TV2 integrates two independent ultrafast recovery diodes in a single insulated ISOTOP housing, enabling shared thermal management while maintaining electrical isolation between anode-cathode paths. Its recovery dynamics are characterized by trr = 30 ns (typ.) at IF = 1 A, dIF/dt = –200 A/µs, VR = 30 V, Tj = 25 °C - and degrade to 37 ns max at same conditions.

Thermal design relies on conduction cooling via the metal baseplate; junction-to-case resistance is 0.55 °C/W total (0.1 °C/W inter-die coupling + 1 °C/W per diode). The device operates up to 150 °C junction temperature and supports pulsed surge currents up to 750 A with sinusoidal 10 ms profile.

Key Specifications

Pinout & Package

STTH10002TV2 uses the ISOTOP package: a 4-terminal insulated metal-base power module with integrated creepage/clearance barriers. Dimensions comply with UL file E81734 (2500 V_rms insulation, UL94 V0 epoxy).

FAQ

What is the maximum junction temperature and how does it affect thermal design?

The STTH10002TV2 has a maximum junction temperature of 150 °C. At this limit, VF rises to 0.80 V (50 A) and trr increases to 37 ns, directly impacting conduction loss and switching efficiency. Thermal design must ensure R_th(j–c) + R_th(c–a) keeps T_j ≤ 150 °C under worst-case load and ambient conditions, using the 0.55 °C/W total junction-to-case resistance as baseline.

How does the ISOTOP package achieve 2500 V_rms insulation?

The ISOTOP package achieves 2500 V_rms insulation through reinforced epoxy molding (UL94 V0 rated), extended creepage distances (>10 mm between terminals), and internal air-gap barriers separating the metal baseplate from each anode/cathode terminal. This construction is certified under UL file E81734 and eliminates need for external insulating washers in most mounting configurations.

Can STTH10002TV2 be used in parallel with another unit for higher current?

No - STTH10002TV2 is not intended for paralleling with identical units due to lack of integrated current-sharing features and mismatched thermal coupling. Its dual-diode structure is optimized for intra-package sharing only. For >100 A systems, use a single higher-rated device (e.g., STTH160L06CW) or implement active current balancing with external sensing and gate control.

What is the significance of the "TV2" suffix in the part number?

The "TV2" suffix denotes the ISOTOP package variant with specific mechanical configuration and packaging format: tube delivery with 40 terminal screws and washers supplied separately (per Table 7). It distinguishes this version from TV1 (identical electrical specs, different packaging logistics) and confirms full production status per Doc ID 12363 Rev 2 (October 2012).
