Product details
Overview
VS-1N2133RA from Vishay Semiconductors is a stud-mount silicon rectifier diode with anode-to-case polarity, rated for 300 V repetitive peak reverse voltage (VRRM), 60 A average forward current (IF(AV)), and 900 A 60 Hz non-repetitive surge current (IFSM). It features low forward voltage drop (1.3 V at rated IF), low thermal resistance (0.65 °C/W junction-to-case), and operates up to +140 °C case temperature - used in high-power industrial DC power supplies and motor drive front-end rectification.
For engineers reviewing the VS-1N2133RA datasheet, VS-1N2133RA pinout, VS-1N2133RA application, or VS-1N2133RA equivalent, this page delivers verified electrical ratings, DO-5 mechanical interface details, thermal derating curves, surge capability data, and validated alternative part options for high-current stud-mount rectifier selection.
Technical Context
This device belongs to the VS-1N2128A series of high-current stud-mount rectifiers. It uses diffusion-controlled silicon PN junction technology optimized for low leakage (<10 mA at rated VRRM) and high surge robustness (I2t = 3400 A2s at 8.3 ms). Its thermal design targets direct mounting to threaded heatsinks with specified torque (3.2–4.2 N·m) and thermal interface grease.
The "R" suffix denotes anode-to-case polarity - critical for proper mounting orientation in isolated heat sink configurations. The DO-5 (DO-203AB) package integrates a 1/4"-28UNF-2A threaded stud as both electrical terminal and mechanical fastener, enabling high-current conduction without external leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V maximum repetitive peak reverse voltage - defines maximum AC line voltage it can block in full-wave bridge or half-wave rectifier topologies. |
| IF(AV) | 60 A average forward current at TC = +140 °C - supports continuous DC output currents up to 60 A when properly heatsinked. |
| IFSM (60 Hz) | 900 A peak non-repetitive surge current - withstands inrush into capacitive loads or short-duration fault conditions without fusing. |
| VFM | 1.3 V maximum forward voltage at rated IF and TJ = 25 °C - determines conduction loss and thermal rise in high-efficiency power conversion stages. |
| RthJC | 0.65 °C/W junction-to-case thermal resistance - enables precise thermal modeling when mounted to a known-sink thermal resistance. |
| TC Range | -65 °C to +140 °C operating case temperature - specifies usable ambient and heatsink temperature envelope for industrial environments. |
| I2t (8.3 ms) | 3400 A2s fusing energy - quantifies single-pulse short-circuit withstand capability under standard 60 Hz half-cycle stress. |
Pinout & Package
VS-1N2133RA uses the DO-5 (DO-203AB) stud-mount package: a hermetically sealed metal case with a 1/4"-28UNF-2A threaded anode stud and insulated cathode flange. Mounting requires controlled torque (3.2–4.2 N·m) on clean, greased surfaces per Vishay specification 95360.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Stud) | Forward current entry point | Threaded metal stud serves as primary anode connection and mechanical mounting interface; must be electrically isolated from heatsink unless system grounding scheme permits. |
| Cathode (Flange) | Forward current exit point | Insulated metal flange provides cathode connection; requires bolt-through mounting with insulating shoulder washer to maintain isolation. |
Key Features
| Feature | Design Value |
|---|---|
| Anode-to-case polarity | Enables direct stud mounting to grounded heatsinks while keeping cathode isolated - simplifies thermal management in high-voltage DC bus designs. |
| Low RthJC (0.65 °C/W) | Reduces junction temperature rise by ~39 °C versus comparable 1.0 °C/W devices at 60 A, extending lifetime and improving reliability in continuous operation. |
| High IFSM (900 A @ 60 Hz) | Supports reliable startup into large electrolytic capacitor banks without degradation - critical for industrial UPS and welder power supplies. |
| JEDEC DO-5 mechanical standard | Ensures interchangeability with legacy 1N2128A-series rectifiers and compatibility with standardized heatsink threading and mounting hardware. |
| Low leakage (≤10 mA @ VRRM) | Minimizes standby power loss and prevents unintended conduction in high-impedance hold-up circuits or snubber networks. |
Applications
| Industrial DC Power Supplies | Motor Drive Front-End Rectification |

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-1N2133A | Cathode-to-case polarity; identical VRRM, IF(AV), IFSM, and thermal specs. | Requires cathode-side mounting - incompatible with anode-grounded heatsink layouts. | Select VS-1N2133A only when cathode must connect directly to chassis ground or heatsink. |
| 1N2133RA (non-VS prefix) | Same electrical and mechanical specs; differs only in packaging and traceability - no functional difference. | No application impact; may differ in lot traceability or screening level per customer requirement. | Choose 1N2133RA if standard JEDEC-compliant part number is required for BOM compliance or legacy procurement systems. |
Compared with VS-1N2133A and 1N2133RA, the VS-1N2133RA offers identical core performance but ensures Vishay's VS-series quality control, extended product longevity, and documented supply chain traceability - making it preferred for new industrial designs requiring long-term component availability.

FAQ
What does the "R" suffix in VS-1N2133RA indicate?
The "R" suffix in VS-1N2133RA explicitly denotes anode-to-case polarity, meaning the threaded stud serves as the anode terminal and the insulated flange is the cathode. This configuration is essential for correct thermal and electrical integration in grounded heatsink systems. VS-1N2133RA must not be substituted with cathode-to-case variants like VS-1N2133A without verifying mounting topology and isolation requirements.
What is the maximum allowable case temperature for VS-1N2133RA?
The maximum allowable case temperature for VS-1N2133RA is +140 °C, as confirmed in the "MAJOR RATINGS AND CHARACTERISTICS" table for the VS-1N2128A series. Derating of IF(AV) begins above this temperature, and operation beyond +140 °C risks irreversible junction degradation. Thermal design must ensure the stud base remains at or below this limit under worst-case load and ambient conditions.
How does VS-1N2133RA compare to VS-1N1187RA in terms of current rating?
VS-1N2133RA is rated for 60 A average forward current (IF(AV)), whereas VS-1N1187RA is rated for 35 A. Both share the same 300 V VRRM and DO-5 package, but VS-1N2133RA uses the higher-current VS-1N2128A series die construction with lower RthJC (0.65 °C/W vs. 1.00 °C/W) and higher IFSM (900 A vs. 500 A), making it suitable for more demanding thermal and surge profiles.
Can VS-1N2133RA be used in a 600 V line application?
No, VS-1N2133RA has a maximum repetitive peak reverse voltage (VRRM) of 300 V and is not rated for 600 V line applications. Attempting use at 600 V would exceed its blocking capability, risking catastrophic avalanche failure. For 600 V systems, select VS-1N1190RA or VS-1N1190A - both explicitly rated for 600 V VRRM in the same DO-5 package.
What torque value should be applied when mounting VS-1N2133RA?
Vishay specifies a mounting torque of 3.2 N·m (28 lbf·in) for lubricated-thread installation on the hexagon head of VS-1N2133RA, per Document Number 95360. Using torque outside the 2.3–4.2 N·m range (depending on thread condition) risks stud deformation, poor thermal contact, or flange cracking - all compromising electrical integrity and thermal performance.
