1N5310

Overview

The JAN1N5310-1/TR is a current regulator diode manufactured by Microchip Technology, formerly Microsemi. It provides a regulated current of 3.63 mA with a maximum peak operating voltage of 100 V and a maximum limit voltage of 2.35 V. The device features a minimum dynamic impedance of 280 kOhms and a minimum knee impedance of 24 kOhms. Designed for through-hole mounting in a DO-7-2 package, it operates within a temperature range of -65°C to +175°C. This component belongs to the 1N5283-1 through 1N5314-1 series of 0.5-watt current regulators.

Feature Summary

• Regulates current over a broad operating voltage and temperature range
• Features double-plug construction for reliability
• Includes internal metallurgical bond
• Qualified per MIL-PRF-19500/463 standards

Applications

• Current limiting circuits
• Constant current sources
• Biasing networks for semiconductor devices

Procurement Notes

Verify the specific ordering suffix (e.g., /TR) against the manufacturer's official datasheet to confirm packaging type and qualification level. Ensure the required military or commercial grade matches the project specifications. Confirm RoHS compliance status if applicable, as commercial versions may differ from qualified variants. Cross-reference the manufacturer part number with distributor listings to ensure authenticity and availability.

Selection Notes

Select this component when a stable current source is required across a wide voltage span. The 3.63 mA rating suits low-power biasing applications. Consider the high peak voltage tolerance for circuits with significant voltage drops. Evaluate the thermal performance within the specified -65°C to +175°C range for harsh environments. Compare impedance characteristics against circuit requirements for stability.

Part Context

This device is part of the 1N5283-1 through 1N5314-1 series, offering currents from 0.22 mA to 4.7 mA in 10% tolerances. It serves as a counterpart to Zener diodes, which regulate voltage rather than current. The series is available in various qualifications including JAN, JANTX, and JANS per MIL-PRF-19500/463. Commercial versions are also offered in surface mount packages like DO-213AB.

Replacement Considerations

Direct substitutes include other parts from the 1N53xx series with matching 3.63 mA ratings. Verify equivalent impedance and voltage ratings when cross-referencing with other manufacturers' current regulator diodes. Ensure package compatibility for through-hole installation.
