Product details

Overview

STPS160H100TV from STMicroelectronics is a high-voltage dual Schottky rectifier in ISOTOP package, rated for 100 V repetitive reverse voltage and 2 × 80 A average forward current per diode, with max forward voltage drop of 0.68 V at 125 °C and 80 A - designed for telecom and computer SMPS where low switching losses and low noise are critical.

For engineers reviewing the STPS160H100TV datasheet, STPS160H100TV pinout, STPS160H100TV application, or STPS160H100TV equivalent, key selection criteria include junction-to-case thermal resistance (0.9 °C/W per diode), 2500 VRMS insulation rating, avalanche power capability (5400 W), and dual-diode configuration enabling interleaved or parallel high-current rectification.

Technical Context

This dual Schottky rectifier integrates two independent high-frequency diodes in a single insulated ISOTOP package, each rated for 100 V VRRM and 80 A IF(AV) at TC = 110 °C. Its low VF (0.59–0.68 V typ./max at 125 °C) and negligible switching losses stem from Schottky barrier construction, avoiding minority-carrier storage delay.

The device supports medium-voltage operation up to 100 V with 150 °C maximum junction temperature, and features 45 pF junction capacitance and 2 A repetitive peak reverse current at 1 kHz - optimized for high-frequency DC-DC converters requiring low EMI and fast transient response.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	100 V - supports input rectification in 48 V telecom systems and 12/24 V industrial SMPS with margin against transients
IF(AV) per diode	80 A - enables 160 A total continuous output current when both diodes used in parallel or interleaved topology
VF (max)	0.68 V at 80 A, 125 °C - limits conduction loss to ≤54 W per diode under full load, reducing heatsink requirements
Rth(j-c) per diode	0.9 °C/W - allows direct mounting to heatsink with predictable thermal rise; total device Rth(j-c) = 0.5 °C/W when both diodes active
Insulation rating	2500 VRMS - meets reinforced isolation requirements for secondary-side rectification in offline PSUs
Junction capacitance	45 pF - minimizes high-frequency displacement current and EMI generation in >100 kHz switching applications
Avalanche energy	5400 W peak (tp = 10 µs) - withstands inductive turn-off surges without failure in unclamped flyback or LLC resonant topologies

Pinout & Package

STPS160H100TV uses the ISOTOP package: a through-hole, insulated, dual-diode housing with four terminals (A1, K1, A2, K2), epoxy-molded body meeting UL94 V0, and mechanical dimensions per ST DocID5384 Rev 5 Table 5 (e.g., D = 37.8–38.2 mm, E = 25.15–25.50 mm).

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first Schottky diode; connects to high-side switch node in synchronous rectifier or boost PFC stage
K1	Cathode 1	Output terminal for first diode; ties to common output rail or inductor node in dual-phase buck converter
A2	Anode 2	Independent anode for second diode; enables phase-split or redundant rectification without shared thermal path
K2	Cathode 2	Second cathode terminal; permits independent routing to reduce parasitic inductance in high-dI/dt layouts

Key Features

Feature	Design Value
Negligible switching losses	No reverse recovery charge (Qrr ≈ 0), eliminating turn-off loss and associated snubbing components in >200 kHz designs
High junction temperature capability	150 °C max Tj rating allows operation in compact, sealed enclosures without derating below 110 °C case temperature
Low leakage current	≤50 mA IR at 125 °C and VRRM - maintains efficiency in high-temperature server PSU environments
Insulated ISOTOP package	2500 VRMS isolation between terminals and heatsink - eliminates need for insulating pads in grounded-chassis applications
Avalanche rated	5400 W peak avalanche power (10 µs pulse) - sustains short-circuit or overload events without parametric shift or hard failure

Applications

Industrial DC-DC Converter

Renewable Energy Inverter Auxiliary Supply

Use Scenario: Isolated 24 V auxiliary supply in motor drive inverters, powered from 600 V DC bus via flyback transformer.

IC Role / Device Role / Timing Role: High-voltage Schottky rectifier on secondary side, operating at 100–200 kHz with minimal EMI.

Use Value: 45 pF junction capacitance and low VF suppress high-frequency ringing, easing EMC filter design and passing CISPR-11 Class A.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-160CTH100	Same ISOTOP package, 100 V VRRM, but 160 A total IF(AV); VF = 0.72 V max at 125 °C - 0.04 V higher than STPS160H100TV	Lacks 2500 VRMS insulation; requires external insulator pad for chassis-grounded heatsinks	Prefer when cost sensitivity outweighs insulation requirement and thermal margin permits higher VF
ON Semiconductor MBR16100CT	TO-220AB package, 100 V, 160 A total IF(AV); VF = 0.82 V max - significantly higher conduction loss	No insulation rating; not suitable for isolated secondary-side use without creepage/clearance redesign	Select only for non-isolated, low-cost industrial supplies where heatsink isolation is already managed externally

Compared with VS-160CTH100 and MBR16100CT, STPS160H100TV uniquely combines 2500 VRMS insulation, lowest VF (0.68 V), and matched dual-diode thermal coupling - making it optimal for space-constrained, safety-critical telecom and server SMPS where reliability and efficiency are co-prioritized.

FAQ

What is the maximum recommended torque for mounting screws on STPS160H100TV?

STMicroelectronics specifies a recommended torque value of 1.3 N·m and a maximum torque of 1.5 N·m for the mounting screws. The datasheet strongly advises using only the screws supplied with the device; substitution invalidates warranty and risks mechanical damage to the ISOTOP package or insulation layer.

Can STPS160H100TV be used in parallel configurations across both diodes?

Yes - the device supports simultaneous use of both diodes with coupled thermal behavior. Table 3 defines Rth(c) = 0.14 °C/W coupling resistance, enabling accurate junction temperature calculation: ΔTj(diode1) = P1 × 0.9 + P2 × 0.14, ensuring safe operation under unbalanced loading.

Does STPS160H100TV meet RoHS and REACH requirements?

Yes - ST confirms ECOPACK® compliance, with epoxy meeting UL94 V0 flammability rating and full adherence to RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations and compliance certificates are available via ST's quality portal using order code STPS160H100TV.

How is the 2500 VRMS insulation rating validated?

The 2500 VRMS insulation rating is verified per IEC 60747-5-1, applied between all terminals and the metal heatsink surface for 60 seconds with ≤10 mA leakage current. This rating is intrinsic to the ISOTOP mold compound and internal leadframe spacing - no external insulation is needed for basic insulation in functional earth-referenced systems.
