Product details
Overview
VS-16FL100S05 from Vishay Semiconductors is a fast recovery stud-mount diode rated for 16 A average forward current, 100 V repetitive peak reverse voltage (VRRM), and 225 A non-repetitive surge current (IFSM at 8.3 ms, 100% VRRM reapplied), designed for high-current freewheeling and snubber applications in industrial DC power supplies and motor drive inverters.
For engineers reviewing the VS-16FL100S05 datasheet, VS-16FL100S05 pinout, VS-16FL100S05 application, or VS-16FL100S05 equivalent, key selection criteria include its DO-4 (DO-203AA) stud-cathode package, 225 ns reverse recovery time (trr) at TJ = 25 °C with dIF/dt = 100 A/μs and IF = 1 A, 1100 nC reverse recovered charge (Qrr), and thermal resistance of 1.6 °C/W (junction-to-case, DC operation).
Technical Context
This device belongs to Vishay's VS-16FL(R) series of fast recovery diodes with stud cathode configuration, optimized for high-efficiency switching in rectifier and freewheeling roles where low stored charge and short trr reduce switching losses. It operates across -65 °C to +150 °C junction temperature range and supports sinusoidal or rectangular conduction waveforms up to 180°.
The VS-16FL100S05 uses a silicon PN junction with JEDEC® DO-4 metal-stud construction, featuring fully characterized reverse recovery under standardized test conditions (IF = 1 A to VR = 30 V, dIF/dt = 100 A/μs), and exhibits I²t fusing capability of 160 A²s (t = 10 ms, no voltage reapplied).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive peak reverse voltage; defines safe blocking capability in DC-link or snubber circuits. |
| IF(AV) | 16 A - Average forward current at TC = 100 °C; determines continuous conduction capacity in high-power rectifiers. |
| trr | 225 ns - Reverse recovery time at TJ = 25 °C, IF = 1 A, dIF/dt = 100 A/μs; directly impacts switching loss and EMI in hard-switched converters. |
| Qrr | 1100 nC - Reverse recovered charge under same conditions; lower Qrr reduces turn-off losses and diode-induced voltage spikes. |
| RthJC | 1.6 °C/W - Junction-to-case thermal resistance (DC); enables thermal design of heatsink interface for 16 A continuous operation. |
| IFSM | 225 A - Non-repetitive peak forward surge current (t = 8.3 ms, 100% VRRM reapplied); supports motor-start and fault-current handling. |
| VFM | 1.5 V - Forward voltage drop at TC = 100 °C, IFM = π × 16 A; sets conduction loss baseline in high-current freewheeling paths. |
Pinout & Package
VS-16FL100S05 uses the DO-4 (DO-203AA) stud-mount package with a threaded metal case serving as the cathode terminal and a center stud anode. The package is mechanically robust for high-current, high-temperature environments and requires torque-controlled mounting (1.2–1.5 N·m for lubricated threads).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (stud) | Forward current entry point | Center threaded stud accepts M5 × 0.8 or 10/32" UNF-2A mounting hardware; electrically isolated from case when mounted with insulating washer. |
| Cathode (case) | Forward current exit / heat path | Entire metal housing serves as cathode and primary thermal interface; must be bolted to heatsink with thermal grease for RthJC = 1.6 °C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Short reverse recovery time | 225 ns trr enables use in 20–100 kHz switching converters without excessive turn-off loss or voltage overshoot. |
| Low stored charge | 1100 nC Qrr minimizes energy dissipated during commutation, reducing stress on paired IGBTs or MOSFETs. |
| Stud cathode configuration | DO-4 metal case provides direct thermal path to heatsink and mechanical stability in high-vibration industrial environments. |
| High surge capability | 225 A IFSM (8.3 ms) supports transient overload in motor drives and UPS systems without failure. |
| JEDEC® DO-203AA compliance | Standardized footprint and mounting interface ensures compatibility with existing tooling and heatsink designs. |
Applications
| Industrial DC Power Supplies | Inverters for AC Motor Drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSK160100 | Same VRRM (100 V), higher IF(AV) = 20 A, but trr = 250 ns and Qrr = 1300 nC; TO-247AC package with isolated tab. | Requires PCB mount and insulating hardware; less suitable for high-vibration stud-mount chassis integration. | Select when higher average current headroom is needed and PCB layout permits TO-247 footprint. |
| VS-16E100 | Same DO-4 package and 16 A/100 V rating, but standard recovery (trr ≈ 2.5 μs, Qrr > 10 μC); no S-code suffix. | Not suitable for >5 kHz switching; used only in line-frequency rectification or low-speed choppers. | Choose only for cost-sensitive, low-frequency applications where fast recovery is unnecessary. |
Compared with VS-16FL100S05, VSK160100 offers higher current margin but sacrifices recovery speed and mounting flexibility, while VS-16E100 trades all fast-recovery benefits for lower cost in non-switching roles-making VS-16FL100S05 the optimal balance of speed, ruggedness, and thermal interface for medium-frequency industrial power conversion.

FAQ
What is the maximum junction temperature rating for VS-16FL100S05?
The VS-16FL100S05 has a maximum junction operating temperature range of -65 °C to +150 °C. This wide range supports reliable operation in harsh industrial environments such as motor control cabinets or outdoor power converters. The device's thermal resistance (RthJC = 1.6 °C/W) and derating curves allow full 16 A IF(AV) conduction at TC = 100 °C, making VS-16FL100S05 suitable for continuous-duty applications with adequate heatsinking.
Does VS-16FL100S05 have a stud anode or stud cathode configuration?
VS-16FL100S05 features a stud cathode configuration: the metal case (DO-4 package body) is the cathode, and the center threaded stud is the anode. This is confirmed by the "R" suffix in the part number (per Vishay ordering table: "R = stud reverse polarity") and the mechanical outline showing cathode case connection. Proper mounting requires electrical isolation of the anode stud from the heatsink using an insulating washer and shoulder washer.
What does the "S05" suffix in VS-16FL100S05 indicate?
The "S05" suffix in VS-16FL100S05 specifies the reverse recovery time grade: 225 ns trr at TJ = 25 °C, IF = 1 A, dIF/dt = 100 A/μs (per Recovery Characteristics table). This distinguishes it from S02 (100 ns) and S10 (390 ns) variants in the same voltage/current family. The S05 grade balances speed and surge robustness for general-purpose medium-frequency switching applications.
Can VS-16FL100S05 be used in parallel configurations?
VS-16FL100S05 is not recommended for direct parallel operation without external balancing components. Its forward voltage (VFM = 1.5 V at TC = 100 °C) has typical unit-to-unit variation, and the DO-4 package lacks integrated current-sharing features. For higher current requirements, Vishay recommends using a single higher-rated device or implementing individual series inductors (≥ 100 nH) and matched heatsinking to ensure thermal and dynamic current sharing across multiple VS-16FL100S05 units.
Is VS-16FL100S05 RoHS-compliant and halogen-free?
Yes, VS-16FL100S05 complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay's material categorization standard (document 99912). The device uses lead-free terminations and environmentally compliant internal materials, supporting green manufacturing requirements for industrial equipment sold in EU, North America, and Asia-Pacific markets. Full compliance documentation is available upon request from Aetrix Electronics.
