1N5227BTR

Single Zener Diodes Overview

The onsemi 1N5227BTR is a single silicon Zener diode with a nominal voltage of 3.6 V and a tolerance of ±5%. It operates in the DO-35 axial lead package (CASE 017AG) and dissipates up to 500 mW at 25°C, derating by 4.0 mW/°C above this temperature. The device features a maximum reverse leakage current of 15 µA at 1.0 V and a typical Zener impedance of 24 Ω at a test current of 20 mA. It supports an operating junction temperature range from −65°C to +200°C and is supplied in tape and reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single PN junction structure within a hermetically sealed glass axial lead package.
• Maintains consistent electrical performance across a wide thermal operating range extending from −65°C to +200°C.
• Offers precise voltage tolerance for accurate reference applications without requiring external trimming components.

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection networks
• Clipping and clamping circuits

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required shipping configuration, as the TR suffix indicates tape and reel packaging rather than bulk bags. Confirm compliance requirements such as RoHS and halide-free status directly with the manufacturer documentation before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V regulation point is required with tight manufacturing tolerances. Ensure the circuit design accommodates the specified power dissipation limits and derating curves to maintain reliability under varying ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5252B series of 0.5 W Zener voltage regulators manufactured by onsemi. The series provides a comprehensive selection of standard voltages ranging from 2.4 V to 24.0 V, all housed in the same DO-35 glass axial lead package for interchangeability.

Single Zener Diodes Replacement Considerations

Compatible substitutes include Vishay 1N5227B-TR and Microsemi MQ1N5227BTR-1. Verify package dimensions and electrical characteristics against the original datasheet specifications before implementation.
