Product details
Overview
VS-16F10 from Vishay Semiconductors is a standard recovery power diode in DO-4 (DO-203AA) stud package, rated for 16 A average forward current at 140 °C case temperature, 100 V repetitive peak reverse voltage (VRRM), and 350 A non-repetitive surge current at 50 Hz. It features stud cathode polarity, low thermal resistance (RthJC = 1.6 K/W), and is designed for industrial power conversion.
For engineers reviewing the VS-16F10 datasheet, VS-16F10 pinout, VS-16F10 application, or VS-16F10 equivalent, key selection criteria include its 100 V VRRM rating, 16 A IF(AV) capability, stud-mount thermal interface, single-diode configuration, and suitability for high-surge battery chargers and AC/DC converters requiring robust conduction-angle derating.
Technical Context
This device operates as a single-junction, standard-recovery rectifier with defined forward conduction characteristics across conduction angles (30°–180°), where junction-to-case thermal resistance increases from 1.20 K/W at 30° to 1.6 K/W at DC. Its VF(TO)1 threshold is 0.77 V and rf1 slope resistance is 7.80 mΩ at maximum junction temperature.
Designed for stud mounting with 10-32UNF-2A thread (non-lubricated torque: 1.5 N·m), it supports thermal management via direct heat sink coupling (RthCS = 0.5 K/W with greased surface) and delivers stable performance across -65 °C to +175 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 16 A - maximum average forward current at TC = 140 °C, defining continuous DC or half-sine conduction capability |
| VRRM | 100 V - maximum repetitive peak reverse voltage, sets safe blocking margin in 100 V-rated circuits |
| IFSM (50 Hz) | 350 A - non-repetitive surge current handling for short-duration line transients or startup events |
| RthJC | 1.6 K/W - junction-to-case thermal resistance under DC operation, critical for heatsink sizing |
| TJ Range | -65 °C to +175 °C - operational junction temperature window enabling use in harsh industrial environments |
| VFM | 1.23 V - forward voltage drop at 50 A peak, 25 °C, 400 μs pulse, indicating conduction loss at high transient loads |
| I²t (50 Hz) | 612 A²s - fusing energy rating determining fuse coordination and overcurrent protection design |
Pinout & Package
VS-16F10 uses a two-terminal DO-4 (DO-203AA) stud package with cathode connected to the metal stud base and anode accessible via the top terminal. Mounting is via 10-32UNF-2A threaded stud (M5 × 0.8 option available).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Stud Base | Cathode | Primary heat path and electrical return; must be electrically isolated from chassis unless circuit requires common-cathode topology |
| Top Terminal | Anode | Input-side connection for forward conduction; requires insulated standoff or bushing when mounted to grounded heatsink |
Key Features
| Feature | Design Value |
|---|---|
| High surge current capability | 350 A IFSM at 50 Hz enables reliable operation during motor startup or transformer inrush without failure |
| Stud cathode construction | Direct metal-to-heatsink thermal interface reduces total thermal resistance and improves long-term reliability under cyclic loading |
| Wide conduction-angle derating support | Validated RthJC values from 30° to 180° allow precise thermal design for phase-controlled rectifiers and SCR-driven systems |
| Industrial qualification | Rated for -65 °C to +175 °C TJ and qualified per industrial-level reliability standards for factory automation and power equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-16E10 | Enhanced recovery (soft recovery, lower reverse recovery charge Qrr), same 100 V VRRM and 16 A IF(AV) | Better EMI performance in high-frequency switching environments; not optimized for pure line-frequency rectification | Select VS-16E10 only if reduced noise or snubberless operation is required; VS-16F10 remains preferred for cost-sensitive, low-frequency industrial rectifiers |
| ON Semiconductor MUR1610CT | Ultrafast recovery (trr ≈ 75 ns), dual common-cathode configuration, TO-220AC package, 16 A total | Higher switching efficiency but higher forward voltage (1.7 V typical); unsuitable for stud-mount thermal interface requirements | Choose MUR1610CT for PCB-mounted, high-frequency SMPS; VS-16F10 is superior for bolt-down, high-surge, thermally demanding applications |
Compared with VS-16E10 and MUR1610CT, VS-16F10 offers the lowest thermal resistance (1.6 K/W), highest surge robustness (350 A), and purpose-built stud interface-making it optimal for legacy industrial rectifier designs where reliability under sustained conduction and mechanical ruggedness are prioritized over switching speed.

FAQ
What is the maximum allowable case temperature for continuous operation of VS-16F10?
The VS-16F10 is rated for 16 A average forward current at a case temperature (TC) of 140 °C under 180° conduction. Exceeding this temperature requires derating per Figure 1 in the datasheet; operation above 140 °C risks exceeding the 175 °C maximum junction temperature even with ideal heatsinking.
Does VS-16F10 have reverse polarity (anode-to-stud) configuration?
No, VS-16F10 has standard polarity: cathode connected to the stud base. The "R" suffix in the VS-16F(R) family denotes the reverse-polarity variant (anode-to-stud), but VS-16F10 specifically omits the "R", confirming cathode-to-stud construction per Vishay's ordering code table.
What is the thermal resistance from junction to heatsink (RthJS) for VS-16F10?
VS-16F10 specifies RthJC = 1.6 K/W (junction-to-case) and RthCS = 0.5 K/W (case-to-heatsink) under greased, smooth mounting conditions. Total RthJS is therefore 2.1 K/W, assuming no additional interface resistance-critical for calculating heatsink thermal resistance in system-level thermal design.
Can VS-16F10 replace VS-16F20 in a 200 V circuit?
No, VS-16F10 is rated for 100 V VRRM and must not be used in 200 V circuits. VS-16F20 (VRRM = 200 V) is the correct variant for that voltage class. Substituting VS-16F10 would risk catastrophic reverse breakdown under normal operating voltage stress.
What is the forward voltage drop (VFM) of VS-16F10 at rated current?
The VS-16F10 exhibits a maximum forward voltage drop (VFM) of 1.23 V at 50 A peak, 25 °C, and 400 μs pulse width. At its rated 16 A average current, typical VFM is ~0.95 V (derived from VF(TO)2 = 0.90 V and rf2 = 5.70 mΩ), directly impacting conduction losses in power stage design.
