Product details

Overview

STPS16045TV from STMicroelectronics is a dual-channel 45 V, 160 A (total) insulated power Schottky rectifier in ISOTOP package, with max forward voltage 0.69 V at 80 A per diode and 150 °C max junction temperature, used in high-frequency DC-DC converters and low-voltage inverters.

For engineers reviewing the STPS16045TV datasheet, STPS16045TV pinout, STPS16045TV application, or STPS16045TV equivalent, key selection criteria include dual-diode thermal coupling behavior, 2500 V_RMS insulation rating, 0.55 °C/W total junction-to-case thermal resistance, and conduction loss equation P = 0.48 × I_F(AV) + 0.00262 × I_F(RMS)².

Technical Context

This dual Schottky rectifier integrates two independent 45 V / 80 A diodes in a single insulated ISOTOP housing, enabling shared heatsinking while maintaining galvanic isolation up to 2500 V_RMS. Its negligible reverse recovery charge and dV/dt rating of 10,000 V/µs support operation in hard-switched SMPS topologies above 100 kHz.

The device exhibits asymmetric thermal coupling: R_th(j−c) = 1.0 °C/W per diode, but R_th(c) = 0.1 °C/W between diodes, meaning simultaneous conduction causes ∆T_j(diode 1) = P₁ × 1.0 + P₂ × 0.1 - critical for parallel-output or interleaved converter designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	45 V - supports 36 V nominal bus systems with 25 % margin against transients
I_F(AV)	160 A total (80 A per diode) - enables high-current output stages without paralleling discrete devices
V_F (max)	0.69 V at 80 A, 125 °C - reduces conduction loss to ~55 W per diode at full rated current
R_th(j−c)	0.55 °C/W total - allows 110 W dissipation with ≤60 °C case-to-ambient rise using standard heatsink
Insulation	2500 V_RMS - meets reinforced isolation requirements for secondary-side rectification in offline PSUs
C_j	45 pF - limits capacitive switching loss and EMI generation in >500 kHz converters
dV/dt	10,000 V/µs - prevents false turn-on during fast voltage transitions in synchronous rectifier gate drive circuits

Pinout & Package

Package: ISOTOP - insulated metal package with integrated ceramic barrier, 28 g mass, 12.0 mm × 8.0 mm base footprint, screw-mountable (M4, 1.3 N·m recommended torque), UL94 V0 epoxy encapsulation.

Pin/Terminal	Circuit Role	Design Meaning

R_th(j−c) = 0.55 °C/W total	Supports 160 A continuous conduction with ≤85 °C case temperature on 100 cm² aluminum heatsink
45 pF junction capacitance	Minimizes displacement current during switching, easing EMI filter design in high-frequency SMPS

Applications

Server VRM Output Rectification

Use Scenario: Secondary-side rectification in 48 V input, 12 V/200 A telecom power module with forced-air cooling.

IC Role / Device Role / Timing Role: Dual-anode, common-cathode configuration used for center-tapped transformer full-wave rectification.

Use Value: 2500 V_RMS insulation eliminates creepage/clearance compliance risk on PCB, reducing layout area by 35 %.

Industrial Motor Drive Freewheeling

Battery Protection Circuit

Use Scenario: Bidirectional freewheeling path across H-bridge IGBTs in 48 V BLDC inverter driving HVAC compressors.

IC Role / Device Role / Timing Role: A1/K1 and A2/K2 independently clamp inductive kickback from upper and lower legs during PWM dead-time.

Use Value: 10,000 V/µs dV/dt rating prevents spurious conduction during 600 V/µs bus transients, eliminating snubber losses.

Use Scenario: Reverse-polarity and overvoltage protection for Li-ion battery packs in portable medical equipment.

IC Role / Device Role / Timing Role: Anodes tied to battery terminals, cathodes joined to load - blocks reverse current while passing 160 A charge/discharge pulses.

Use Value: 900 A non-repetitive surge rating withstands 10 ms inrush events during hot-plug battery insertion without degradation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-160CTQ045PbF	Same 45 V / 160 A rating, but TO-247AC package (non-insulated); R_th(j−c) = 0.75 °C/W; no isolation barrier	Requires external insulating pad and larger creepage spacing; unsuitable for reinforced isolation designs	Select only when board-level isolation is already implemented and thermal budget permits higher R_th
ON Semiconductor MBR1645CT	45 V / 160 A, TO-220AB package; V_F = 0.75 V @ 80 A; R_th(j−c) = 1.0 °C/W; no insulation	Limited to non-isolated secondary rails; higher conduction loss and thermal resistance reduce usable current by ~22 % at same T_c	Acceptable for cost-sensitive, low-density industrial supplies where isolation and efficiency are secondary

Compared with VS-160CTQ045PbF and MBR1645CT, STPS16045TV uniquely delivers system-level integration via built-in 2500 V_RMS isolation and 0.55 °C/W thermal resistance - enabling smaller heatsinks, simplified safety certification, and higher power density in space-constrained telecom and server PSUs.

FAQ

What is the maximum allowable case temperature for continuous 160 A operation?

The datasheet specifies I_F(AV) = 160 A at T_c = 75 °C with duty cycle δ = 0.5. At full DC operation (δ = 1), derating applies: maximum case temperature drops to 55 °C to maintain safe junction temperature ≤150 °C, based on R_th(j−c) = 0.55 °C/W and calculated power dissipation of ~110 W.

Can STPS16045TV be used in synchronous rectification mode with external gate drivers?

No - STPS16045TV is a passive Schottky diode, not a MOSFET-based synchronous rectifier. It lacks gate terminals and cannot be actively controlled. Its ultra-low V_F and zero Q_rr make it ideal for self-driven or quasi-resonant topologies where active control isn't required or feasible.

How does the 0.1 °C/W coupling resistance affect thermal design when both diodes conduct simultaneously?

When both diodes carry current, heat from Diode 2 raises Diode 1's junction temperature by P₂ × 0.1 °C/W - adding to its own self-heating (P₁ × 1.0 °C/W). This cross-coupling must be included in thermal modeling; at 80 A per diode, total ∆T_j exceeds 120 °C unless case temperature is held below 50 °C.

Is the ISOTOP package compatible with automated optical inspection (AOI) after reflow soldering?

Yes - the ISOTOP package has coplanar, solderable terminals (A1/K1/A2/K2) with defined mechanical tolerances (±0.2 mm), and its flat ceramic-insulated base provides consistent reflectivity. AOI systems calibrated for TO-247 or D²PAK footprints can reliably detect solder joint integrity and alignment when configured for 12.0 mm × 8.0 mm body dimensions.
