Product details
Overview
1N752AE3/TR from Microsemi is a 5.6 V, ±5% tolerance, 500 mW axial-leaded silicon Zener diode in DO-35 (DO-204AH) glass package, qualified to JANTX level per MIL-PRF-19500/127, with 8 Ω dynamic impedance at 50 mA and temperature coefficient of –0.028%/°C to +0.036%/°C, used for precision voltage regulation in military power supply reference circuits.
For engineers reviewing the 1N752AE3/TR datasheet, 1N752AE3/TR pinout, 1N752AE3/TR application, or 1N752AE3/TR equivalent, key selection factors include its hermetically sealed DO-35 package, RoHS-compliant matte-tin plating, 50 µA maximum reverse current at 2.5 V, and linear power derating from 500 mW at 50°C lead temperature to zero at 175°C.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain stable output voltage across varying load and temperature conditions. Its metallurgical bond construction ensures reliability under thermal cycling and radiation exposure, and it exhibits minimal junction capacitance suitable for low-noise analog references.
The 1N752AE3/TR is specified for operation from –65°C to +175°C, with thermal resistance junction-to-lead of 250°C/W and junction-to-ambient of 300°C/W on PCB mounting. It delivers regulated 5.6 V at IZT = 50 mA, with dynamic impedance ZZT = 8 Ω and reverse leakage IR ≤ 5 µA at VR = 2.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.6 V at IZT = 50 mA - defines nominal regulation point for stable reference generation |
| Zener Tolerance | ±5% - sets absolute voltage accuracy band (5.32–5.88 V) for design margining |
| Power Dissipation | 500 mW @ TL = 50°C - limits continuous thermal stress with linear derating to zero at 175°C |
| Dynamic Impedance ZZT | 8 Ω @ IZT = 50 mA - determines output voltage variation under load current changes |
| Reverse Leakage IR | ≤5 µA @ VR = 2.5 V - ensures low quiescent current in standby or high-impedance bias networks |
| Temp. Coefficient αVZ | –0.028%/°C to +0.036%/°C - quantifies voltage drift over operating temperature range |
| Forward Voltage VF | 1.1 V @ IF = 200 mA - defines conduction drop when used in forward-biased protection paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N752A-1 | Same electrical specs but non-RoHS, non-tape-and-reel; lacks e3 and TR suffixes | Requires manual loading or custom reel; not compliant for RoHS-mandated programs | Select 1N752A-1 only for legacy repair or non-RoHS military builds where tape-and-reel is unnecessary |
| BZX55C5V6 | Commercial-grade, 5% tolerance, 500 mW, DO-35, but no MIL qualification or radiation hardness data | Suitable for industrial controls but not certified for aerospace or radiation environments | Choose BZX55C5V6 for cost-sensitive commercial designs where JANTX reliability and TID performance are not required |
Compared with 1N752A-1 and BZX55C5V6, the 1N752AE3/TR uniquely combines JANTX-level military qualification, RoHS compliance, and EIA-296 tape-and-reel packaging-enabling direct use in high-reliability production lines without rework or compliance waivers.

FAQ
What is the Zener voltage and tolerance of the 1N752AE3/TR?
The 1N752AE3/TR has a nominal Zener voltage of 5.6 V with a ±5% tolerance, meaning its actual regulation voltage falls between 5.32 V and 5.88 V at IZT = 50 mA and 25°C. This tolerance is defined by the "A" suffix in the part number and applies across the full military temperature range when derated per specification.
Is the 1N752AE3/TR RoHS compliant and what does the "e3" suffix indicate?
Yes, the 1N752AE3/TR is RoHS compliant, as confirmed by the "e3" suffix in its nomenclature. This denotes RoHS-compliant matte-tin plating applied to the leads, meeting EU Directive 2011/65/EU requirements. The e3 marking applies only to commercial-grade versions and is validated per Microsemi's qualification documentation for this part number.
What package type and lead configuration does the 1N752AE3/TR use?
The 1N752AE3/TR uses the DO-35 (DO-204AH) hermetically sealed axial-glass package with tin-lead or RoHS-compliant matte-tin plated leads. The cathode is marked by a visible band; the banded end must be held positive relative to the anode for proper Zener regulation operation.
What is the maximum power dissipation and thermal derating behavior of the 1N752AE3/TR?
The 1N752AE3/TR is rated for 500 mW average power dissipation at a lead temperature (TL) of 50°C, with linear derating to zero at 175°C. When mounted on a PCB, it delivers 400 mW at 55°C ambient, derating linearly to zero at 175°C. Thermal resistance junction-to-lead is 250°C/W, and junction-to-ambient is 300°C/W.
Does the 1N752AE3/TR have radiation hardness certification and supporting documentation?
Yes, the 1N752AE3/TR is inherently radiation hard as described in Microsemi MicroNote 050, and its JANTX qualification per MIL-PRF-19500/127 includes radiation survivability validation. While no discrete TID value is published in the T4-LDS-0288 datasheet, the metallurgical bond construction and qualification framework support operation in high-radiation environments typical of LEO and MEO satellite missions.
