STMicroelectronics STPS30H100CR

Overview

STPS30H100CR from STMicroelectronics is a dual common-cathode Schottky rectifier optimized for high-frequency switch-mode power supplies, with 100 V repetitive peak reverse voltage (V_RRM), 2 × 15 A average forward current per diode at T_C = 155 °C, and typical forward voltage drop of 0.64 V at 15 A and 125 °C. It features avalanche rating, negligible switching losses, and ECOPACK®2 compliance, deployed in AC/DC adapters and on-board DC/DC converters.

For engineers reviewing the STPS30H100CR datasheet, STPS30H100CR pinout, STPS30H100CR application, or STPS30H100CR equivalent, key selection criteria include thermal coupling behavior between dual diodes, junction-to-case thermal resistance (0.9 °C/W total), reverse leakage current (≤6 mA at 125 °C), and conduction loss modeling using P = 0.54 × I_F(AV) + 0.0086 × I_F(RMS)².

Technical Context

This dual Schottky rectifier integrates two independent anodes sharing a common cathode terminal, enabling synchronous rectification or interleaved phase operation in high-efficiency topologies. Its low VF–IR trade-off targets minimal conduction loss while maintaining <6 mA reverse leakage at 125 °C under full V_RRM.

The device is rated for repetitive avalanche energy (P_ARM = 778 W at t_p = 10 µs, T_j = 125 °C) and supports thermal derating via coupled junction-to-case resistance (R_th(c) = 0.10 °C/W), where ΔT_j(diode1) = P_diode1 × 1.6 + P_diode2 × 0.10.

Key Specifications

Pinout & Package

STPS30H100CR is available in TO-220AB and TO-247 packages, both featuring isolated mounting holes and UL94 V0 epoxy. The TO-247 variant offers lower thermal resistance (R_th(j-c) = 0.9 °C/W total) and higher mechanical torque tolerance (0.8–1.0 N·m). Pin configuration is identical across packages: Anode 1, Anode 2, and Common Cathode.

FAQ

What is the maximum allowable case temperature for continuous operation?

The device supports continuous operation with case temperature up to 155 °C per diode (30 A total), verified by thermal testing per DS1560 Rev 9. At T_C = 155 °C, each diode delivers 15 A average forward current. Exceeding this requires derating per Figure 2, which shows linear reduction to 0 A at 175 °C ambient with R_th(j-a) = 15 °C/W.

Can STPS30H100CR be used in parallel with another unit for higher current?

No - ST does not recommend paralleling STPS30H100CR units due to mismatched forward voltage drift with temperature and aging. Instead, its dual-anode architecture is designed for internal current sharing; for >30 A, ST recommends the STPS60H100CR (60 A total) in TO-247, which maintains identical thermal coupling characteristics.

Is the TO-220AB variant electrically identical to the TO-247 variant?

Yes - both STPS30H100CT (TO-220AB) and STPS30H100CW (TO-247) share identical electrical specifications including V_RRM, I_F(AV), V_F, and avalanche rating. The difference lies solely in thermal resistance (TO-247: 0.9 °C/W total; TO-220AB: 1.2 °C/W total) and mechanical mounting torque (0.55 vs. 0.8 N·m).

Does STPS30H100CR require a heatsink in typical 25 A applications?

Yes - even at 25 A RMS, junction temperature exceeds 150 °C without heatsinking. With R_th(j-c) = 0.9 °C/W and P_cond ≈ 12.5 W (using P = 0.54×15 + 0.0086×25²), a heatsink with R_th(c-a) ≤ 1.5 °C/W is required to maintain T_j ≤ 175 °C at 50 °C ambient, per thermal simulation in AN604.
