Product details
Overview
1N753AE3 from Microsemi is a 500 mW, 6.2 V ±5% Zener diode in DO-35 glass axial package, qualified to JANTX level per MIL-PRF-19500/127, with 3 Ω dynamic impedance at 20 mA and +0.045 %/°C temperature coefficient - used for precision voltage reference and regulation in military power supplies and analog front-ends.
For engineers reviewing the 1N753AE3 datasheet, 1N753AE3 pinout, 1N753AE3 application, or 1N753AE3 equivalent, key selection criteria include Zener voltage tolerance, junction-to-lead thermal resistance (250 °C/W), reverse leakage (≤5 µA at 3.5 V), RoHS compliance status, and MIL-qualified reliability grade.
Technical Context
The 1N753AE3 operates as a reverse-biased silicon Zener regulator with metallurgical bond construction, enabling stable breakdown behavior across -65°C to +175°C. Its 6.2 V nominal Zener voltage is specified at IZT = 20 mA with ZZT = 3 Ω, and exhibits a positive temperature coefficient (+0.045 %/°C) indicating increasing VZ with temperature.
It is rated for 500 mW average power dissipation at TL = 50°C with 0.375" lead length, derating linearly to zero at 175°C. The device features low capacitance, ESD insensitivity per MIL-STD-750 Method 1020, and inherent radiation hardness per MicroNote 050.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N753A | Same electrical specs but non-RoHS tin-lead plating; lacks e3 suffix | Restricted to legacy military assemblies where Pb exemption applies | Select when RoHS compliance is not required and legacy procurement rules apply |
| 1N753AUR-1 | MELF DO-213AA surface-mount package; identical VZ, ZZT, and αVZ | Requires PCB redesign for SMT placement; no axial through-hole mounting | Select for space-constrained or automated assembly designs needing same regulation performance in MELF form |
Compared with 1N753AE3, the 1N753A offers identical regulation performance without RoHS compliance, while 1N753AUR-1 delivers the same electrical behavior in a surface-mount MELF package - choice depends on plating requirements and board assembly method.

FAQ
What is the Zener voltage tolerance of the 1N753AE3?
The 1N753AE3 has a nominal Zener voltage of 6.2 V with a ±5% tolerance, meaning its actual breakdown voltage falls between 5.89 V and 6.51 V at 20 mA and 25°C. This tolerance is defined by the "A" suffix in the part nomenclature and applies across the full military temperature range when operated within rated power limits.
Is the 1N753AE3 RoHS compliant?
Yes, the 1N753AE3 is RoHS compliant, as indicated by the "e3" suffix in its designation. It uses annealed matte-tin plating on its axial leads and meets EU RoHS Directive 2011/65/EU requirements. This compliance applies only to the commercial-grade version; MIL-qualified variants without "e3" use tin-lead plating.
What is the maximum power dissipation rating for the 1N753AE3?
The 1N753AE3 is rated for 500 mW average power dissipation at a lead temperature (TL) of +50°C with 0.375 inch (9.53 mm) lead length from the body. Power linearly derates to zero at +175°C, and for PCB-mounted operation, it is rated at 400 mW at +55°C ambient per Figure 2 in the datasheet.
Does the 1N753AE3 have a positive or negative temperature coefficient?
The 1N753AE3 has a positive temperature coefficient of +0.045 %/°C at 25°C, meaning its Zener voltage increases with rising junction temperature. This behavior is typical for Zener diodes above ~5.6 V and supports predictable drift compensation in temperature-stable reference designs.
What packaging options are available for the 1N753AE3?
The 1N753AE3 is supplied in the DO-35 (DO-204AH) axial-leaded glass package. Tape-and-reel packaging is available with the "TR" suffix (e.g., 1N753AE3TR). Alternate form factors include the surface-mount MELF DO-213AA variant designated 1N753AUR-1, which shares identical electrical characteristics but requires SMT assembly.
