Diodes Incorporated 1N4760A-T

Overview

1N4760A-T from Diodes Incorporated is a 1.0 W, 68 V ±5% tolerance Zener diode in DO-41 glass package, rated for 3.7 mA test current, 150 Ω maximum Zener impedance at I_ZT, and −65 °C to +175 °C operating temperature range; used for precision voltage regulation and overvoltage protection in DC power supplies.

For engineers reviewing the 1N4760A-T datasheet, 1N4760A-T pinout, 1N4760A-T application, or 1N4760A-T equivalent, key selection criteria include nominal Zener voltage (68 V), power dissipation (1.0 W), Zener impedance (150 Ω max), thermal resistance (175 °C/W), and DO-41 mechanical compatibility with through-hole PCB layouts.

Technical Context

This discrete Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load and line conditions. Its 68 V nominal Zener voltage is specified at 3.7 mA test current (I_ZT) with 5% tolerance, and exhibits a positive temperature coefficient of +0.06 to +0.095 %/°C.

Designed for DC voltage regulation and transient suppression, it delivers 51.7 V minimum knee voltage (V_ZS) at 0.25 mA and withstands up to 65 mA surge current (8.3 ms waveform). Thermal derating begins above 50 °C at 6.67 mW/°C when leads are held at 50 °C with 9.5 mm length.

FAQ

What is the Zener voltage tolerance for 1N4760A-T?

The 1N4760A-T has a nominal Zener voltage of 68 V with a tolerance of ±5%, measured at 3.7 mA test current (I_ZT) under thermal equilibrium and DC conditions per DS18007 Rev. 20–4.

Is 1N4760A-T RoHS compliant?

Yes, the 1N4760A-T features a lead-free Sn96.5Ag3.5 termination and complies with EU Directive 2002/95/EC (RoHS), with exemptions applied for glass encapsulation and high-temperature soldering as permitted in Annex Notes 5 and 7.

Can 1N4760A-T be used in surface-mount designs?

No - the 1N4760A-T uses a DO-41 axial glass package intended for through-hole mounting only. It lacks SMD-compatible terminations or footprint geometry; alternative SMT Zeners like BZX84-C68 require redesign.

What is the maximum surge current rating?

The 1N4760A-T is rated for 65 mA maximum non-repetitive surge current with an 8.3 ms waveform, as specified in the Electrical Characteristics table on page 2 of DS18007 Rev. 20–4.
