Product details
Overview
VS-1N2135RA from Vishay Semiconductors is a stud-mount silicon rectifier diode with anode-to-case polarity, rated for 40 A average forward current at 150 °C case temperature, 400 V maximum repetitive peak reverse voltage (VRRM), and 800 A peak non-repetitive surge current (60 Hz). It features low forward voltage drop (1.3 V at 126 A), low leakage current (2.5 mA at rated VRRM and TC), and is designed for high-reliability industrial AC/DC power conversion in welding equipment and motor drive snubber circuits.
For engineers reviewing the VS-1N2135RA datasheet, VS-1N2135RA pinout, VS-1N2135RA application, or VS-1N2135RA equivalent, key selection criteria include its DO-5 (DO-203AB) stud package, anode-to-case thermal path, 0.65 °C/W junction-to-case thermal resistance, and compatibility with holed threaded heatsinks per Vishay's mechanical recommendations.
Technical Context
This device belongs to the VS-1N1183A series of high-current, stud-mounted power rectifiers optimized for line-frequency (50/60 Hz) operation in harsh thermal environments. Its design emphasizes robust surge handling (I2t = 2650 A²s at 8.3 ms) and stable performance across -65 °C to +200 °C junction temperature range.
The anode-to-case configuration (denoted by "RA" suffix) enables direct thermal coupling to heatsinks via threaded stud mounting, while the low RthJC and high IFSM support high-duty-cycle industrial switching applications where transient overloads and sustained conduction losses must be managed simultaneously.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking capability at TJ = -65 °C to +200 °C; suitable for 280 V RMS AC input systems with safety margin. |
| IF(AV) | 40 A at TC = 150 °C - Continuous DC output current capability when mounted on properly torqued heatsink; derates linearly below 150 °C. |
| VFM | 1.3 V at IF = 126 A, TJ = 25 °C - Low conduction loss enables high-efficiency rectification in high-current welder primary supplies. |
| IFSM | 800 A (60 Hz half-cycle) - Withstands short-duration line surges without fusing; critical for motor-start and transformer inrush immunity. |
| RthJC | 0.65 °C/W - Enables efficient heat transfer from silicon die to heatsink; requires 2.3–4.2 N·m mounting torque depending on thread lubrication. |
| IR(AV) | 2.5 mA at VRRM = 400 V, TC = max - Low leakage preserves efficiency in high-impedance hold-off stages and reduces standby power loss. |
| TJ Range | -65 °C to +200 °C - Supports operation in extreme ambient environments including engine compartments and industrial ovens. |
Pinout & Package
VS-1N2135RA uses the DO-5 (DO-203AB) stud-mount package: anode terminal is the threaded metal stud (M10 × 1.5, 1/4"-28 UNF-2A), cathode is the insulated base flange. Mounting requires torque control (2.3–4.2 N·m) and thermal interface grease for optimal RthCS = 0.25 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Stud) | Current entry point under forward bias; electrically and thermally connected to case | Must be isolated from chassis ground unless circuit topology requires common-anode configuration; provides primary thermal path to heatsink. |
| Cathode (Flange) | Current exit point under forward bias; electrically isolated from stud | Connected to PCB or busbar via insulated mounting hardware; serves as reference node for output filtering and sensing. |
Key Features
| Feature | Design Value |
|---|---|
| Anode-to-case polarity (RA suffix) | Enables direct thermal anchoring of anode to heatsink while maintaining cathode isolation-ideal for grounded-cathode rectifier topologies. |
| Low VFM (1.3 V @ 126 A) | Reduces conduction losses by ~25% versus legacy 1.7 V diodes at same current, lowering thermal stress in high-duty-cycle welder supplies. |
| High IFSM (800 A, 60 Hz) | Supports repeated exposure to transformer inrush and motor stall currents without degradation-validated per JEDEC JESD22-A114. |
| 0.65 °C/W RthJC | Allows 40 A continuous operation at 150 °C case temperature with ≤26 W dissipation-enabling compact heatsink designs in space-constrained enclosures. |
| JEDEC DO-5 mechanical standard | Ensures interchangeability with legacy stud-mount rectifiers and compatibility with industry-standard holed heatsinks and mounting hardware. |
Applications
| Industrial Welding Power Supplies | Motor Drive Snubber Circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current stud-mount rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VS-1N2135A | Cathode-to-case polarity; identical VRRM, IF(AV), VFM, and thermal specs. | Requires insulated stud mounting; unsuitable for grounded-anode topologies. | Select VS-1N2135A only when cathode must be referenced to heatsink/chassis ground. |
| VS-1N2131RA | 200 V VRRM; same package, IF(AV) = 40 A, RthJC = 0.65 °C/W, but lower IFSM = 800 A (50 Hz). | Limited to 140 V RMS AC inputs; insufficient for 400 V three-phase rectification. | Use VS-1N2131RA only in lower-voltage industrial controls where 200 V blocking suffices and cost optimization is prioritized. |
Compared with VS-1N2135A and VS-1N2131RA, the VS-1N2135RA uniquely combines 400 V blocking, anode-to-case polarity, and 800 A 60 Hz surge rating-making it the sole option for grounded-anode 400 V AC rectification with high thermal margin.

FAQ
What is the maximum case temperature for continuous operation of the VS-1N2135RA?
The VS-1N2135RA supports continuous operation up to 150 °C case temperature when delivering its rated 40 A average forward current. This rating is specific to the VS-1N1183A series and reflects optimized thermal design for stud-mounted configurations. Exceeding 150 °C requires derating per the manufacturer's IF(AV) vs. TC curve in Figure 6 of document 93492.
Does the VS-1N2135RA have a specified reverse recovery time (trr)?
No, the VS-1N2135RA is a standard silicon power rectifier-not a fast or ultrafast recovery diode-and does not specify reverse recovery time in its datasheet. Its design prioritizes high surge current and low forward voltage over switching speed, making it appropriate for 50/60 Hz line-frequency applications but not for high-frequency SMPS topologies.
What is the correct mounting torque for the VS-1N2135RA stud?
The recommended mounting torque for the VS-1N2135RA's M10 × 1.5 stud is 2.3 N·m (20 lbf·in) for lubricated threads tightened on the nut, or 3.2 N·m (28 lbf·in) for lubricated threads tightened on the hexagon. Proper torque ensures optimal thermal contact (RthCS = 0.25 °C/W) without damaging the DO-5 package seal.
Can the VS-1N2135RA be used in parallel with other diodes for higher current capacity?
Yes, the VS-1N2135RA can be paralleled, but only with matched units and individual ballast resistors or carefully balanced thermal mounting to ensure current sharing. Its forward voltage variation (±5% typical) and thermal coupling characteristics require system-level validation-Vishay does not guarantee inherent current-sharing behavior without external balancing.
Is the VS-1N2135RA RoHS-compliant and halogen-free?
Yes, the VS-1N2135RA complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay's material declaration in document 99912. The device contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and all bromine and chlorine content is below 900 ppm.
