1N3736

Single Diodes Overview

The 1N3736 is a silicon power rectifier manufactured by Microchip Technology, housed in a DO-9 stud mount package. It features a maximum repetitive peak reverse voltage of 200 V and supports a continuous forward current of 275 A. The device exhibits a non-repetitive peak surge current capability of 4500 A and a maximum operating junction temperature of 200 °C. Constructed with glass-to-metal seal technology, it offers high surge current handling and soft recovery characteristics suitable for demanding power conversion applications.

Single Diodes Feature Summary

• Glass-to-metal seal construction for robust environmental sealing
• High surge current capability to withstand transient loads
• Soft recovery characteristic to minimize switching noise

Single Diodes Applications

• Industrial power supplies
• Motor drive systems
• Welding equipment

Single Diodes Procurement Notes

Verify the manufacturer origin carefully, as the 1N3736 designation is utilized by multiple vendors including Microchip, Powerex, and Digitron. Confirm that the specific unit acquired matches the required electrical parameters, particularly the 200V rating and 275A current capacity. Ensure the DO-9 package style and terminal configuration align with the intended mounting hardware before finalizing procurement.

Single Diodes Selection Notes

Select this component when a high-current rectifier with a 200V blocking voltage is required in a stud-mount form factor. The DO-9 package facilitates direct heatsink mounting for efficient thermal management. Consider the 200°C maximum junction temperature for high-temperature environments. Evaluate the 4500A surge rating against potential inrush currents in the target circuit design to ensure adequate safety margins.

Single Diodes Part Context

The 1N3736 belongs to a family of high-power silicon rectifiers designed for industrial applications. Similar variants in the series include the 1N3737 (300V), 1N3740 (600V), and 1N3741 (800V), all sharing the same 275A current rating and DO-9 package. This numbering convention typically indicates increasing reverse voltage ratings within the same physical footprint and current handling class.

Single Diodes Replacement Considerations

Direct substitutes include the 1N3737, 1N3740, and 1N3741 from manufacturers such as New Jersey Semiconductor or Microchip, provided the circuit voltage requirements are met. These parts share identical current ratings and package styles but offer higher reverse voltage capabilities.
