Product details
Overview
VS-VSKC166/16PBF from Vishay Semiconductors is a single-diode, high-voltage standard recovery power module in INT-A-PAK package, rated for 165 A average forward current (IF(AV)), 1600 V maximum repetitive peak reverse voltage (VRRM), and 3500 VRMS isolation. It features glass-passivated chips, DBC ceramic (Al₂O₃) electrical isolation, and is designed for industrial power conversion systems requiring robust surge handling and thermal stability.
For engineers reviewing the VS-VSKC166/16PBF datasheet, VS-VSKC166/16PBF pinout, VS-VSKC166/16PBF application, or VS-VSKC166/16PBF equivalent, key selection criteria include its 165 A IF(AV) rating at 100 °C case temperature, 0.20 K/W junction-to-case thermal resistance, 4000 A IFSM (10 ms, 50 Hz), 80 kA²s I²t fusing capability, and UL E78996 approval - all critical for high-reliability DC motor drives, battery chargers, and welder rectifier stages.
Technical Context
This device belongs to Vishay's VS-VSK series of industrial-grade power diode modules, configured as a single diode (circuit code "E") with isolated baseplate. Its DBC Al₂O₃ substrate enables 3500 VRMS insulation between terminals and heatsink, supporting safe operation in grounded-heatsink topologies.
The VS-VSKC166/16PBF delivers low conduction losses via dual-threshold forward voltage characteristics: VF(TO)₁ = 0.73 V and rt₁ = 1.5 mΩ at low-current conduction, scaling to VF(TO)₂ = 0.88 V and rt₂ = 1.26 mΩ under full-load conditions - enabling accurate thermal modeling across duty cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 165 A at TC = 100 °C - defines continuous DC or half-sine conduction capability without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current standard recovery diode module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VS-VSKJ166/16PBF | Two-diode common-anode configuration (vs. single diode); identical IF(AV), VRRM, and thermal specs | Required for center-tapped transformer rectifiers or dual-output supplies; not interchangeable in single-diode layouts | Select only when circuit topology requires dual-anode sharing; PCB layout and terminal routing differ significantly |
| IXYS MDA165-16N1 | Same 165 A/1600 V rating but TO-247-3L package; higher RthJC = 0.25 K/W; no integrated isolation | Suitable for lower-isolation systems with external insulating hardware; requires additional creepage/clearance management | Prefer VS-VSKC166/16PBF when baseplate isolation, UL certification, or simplified mounting are mandatory |
Compared with VS-VSKJ166/16PBF, the VS-VSKC166/16PBF offers simpler single-diode integration and avoids redundant anode routing; versus MDA165-16N1, it eliminates external isolation components and reduces assembly risk in safety-critical rectifier designs.

FAQ
What is the maximum allowable case temperature for continuous operation of VS-VSKC166/16PBF?
The VS-VSKC166/16PBF is rated for continuous operation at a maximum case temperature (TC) of 100 °C, as specified in its major ratings table. Exceeding this temperature requires derating of IF(AV) per the conduction-angle curves in Figures 1–2 of the datasheet. At TC = 100 °C, the device delivers its full 165 A IF(AV) rating under 180° half-sine conduction.
Does VS-VSKC166/16PBF have built-in thermal protection or monitoring features?
No, VS-VSKC166/16PBF is a passive power diode module with no integrated thermal sensors or protection circuitry. Thermal management must be implemented externally using heatsink temperature monitoring, current derating, or system-level thermal shutdown logic. Its RthJC = 0.20 K/W allows accurate junction temperature estimation when case temperature is measured.
Can VS-VSKC166/16PBF be used in parallel configurations to increase current capacity?
VS-VSKC166/16PBF is not characterized or recommended for forced-current-sharing parallel operation. Its forward voltage characteristics (VF(TO)₁ = 0.73 V, rt₁ = 1.5 mΩ) exhibit typical unit-to-unit variation that can cause current imbalance. For higher current requirements, Vishay recommends selecting a higher-rated module such as VS-VSKC196/16PBF or VS-VSKC236/16PBF instead.
What is the mounting torque specification for VS-VSKC166/16PBF's M6 screws?
The recommended mounting torque for the three M6 x 10 screws on VS-VSKC166/16PBF is 4 to 6 Nm, with ±10 % tolerance. A thermal interface compound is advised, and torque should be rechecked after 3 hours to accommodate compound spreading. Lubricated threads are required to achieve consistent clamping force and minimize baseplate stress.
Is VS-VSKC166/16PBF compliant with RoHS and REACH regulations?
Yes, the "PbF" suffix in VS-VSKC166/16PBF explicitly denotes lead-free (RoHS-compliant) construction per EU Directive 2011/65/EU Annex II. Vishay confirms full compliance with REACH SVHC requirements, and material declarations are available under document number 99912 on www.vishay.com.
