Product details
Overview
1N752 from Microsemi is a 500 mW, 5.6 V ±5% silicon Zener diode in DO-35 glass axial package, qualified to JANTXV level per MIL-PRF-19500/127, with dynamic impedance of 8 Ω at 50 mA and temperature coefficient of –0.028%/°C to +0.036%/°C, used for precision voltage regulation in military power supplies and reference circuits.
For engineers reviewing the 1N752 datasheet, 1N752 pinout, 1N752 application, or 1N752 equivalent, key selection criteria include Zener voltage tolerance (±5%), junction-to-lead thermal resistance (250 °C/W), maximum reverse current (5 µA at 2.5 V), RoHS compliance status, and MIL-qualified reliability levels (JAN/JANTX/JANTXV).
Technical Context
The 1N752 operates as a two-terminal voltage reference device in reverse breakdown mode, with nominal Zener voltage of 5.6 V measured at IZT = 50 mA. Its metallurgically bonded construction ensures stable regulation across –65 °C to +175 °C operating temperature range and low capacitance for minimal signal distortion.
It exhibits a dual-signature temperature coefficient (–0.028%/°C to +0.036%/°C) indicating voltage stability near zero TC crossing, and supports linear power derating from 500 mW at TL = 50 °C to zero at 175 °C when leads are held at 0.375 inch from body.
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 |
|---|---|---|---|
| 1N4734A | 5.6 V ±5%, 1 W rating, DO-41 package, non-MIL-qualified, higher ZZT (10 Ω) | Commercial industrial use only; lacks radiation hardness and extended temp range | Select when cost-sensitive, non-military designs require higher power margin |
| BZX55C5V6 | 5.6 V ±5%, 500 mW, DO-35, AEC-Q200 qualified, no MIL spec, ZZT = 10 Ω | Automotive-grade alternative; no JANTXV qualification or radiation data | Choose for automotive ECUs where AEC-Q200 compliance is mandatory and MIL specs unnecessary |
Compared with 1N4734A and BZX55C5V6, the 1N752 offers superior thermal stability (–65 °C to +175 °C), verified radiation tolerance, and JANTXV reliability-making it irreplaceable in defense avionics where parameter drift and single-event effects must be eliminated.

FAQ
What is the Zener voltage tolerance for the 1N752?
The 1N752 has a nominal Zener voltage of 5.6 V with a ±5% tolerance, as indicated by the "A" suffix in its nomenclature per the Microsemi T4-LDS-0288 datasheet. This tolerance applies at 25 °C with IZT = 50 mA, and is maintained across the full military temperature range due to metallurgical bond construction and JANTXV qualification.
Is the 1N752 RoHS compliant?
The 1N752 is available in both RoHS-compliant (e3 suffix) and non-RoHS versions, but RoHS compliance is restricted to commercial-grade variants only. JANTXV-qualified 1N752 units are not RoHS compliant, as military specifications require tin-lead plating per MIL-STD-750 method 2026 for solderability and reliability assurance.
What is the maximum reverse current specification for the 1N752?
The 1N752 has a maximum reverse current (IR) of 5 µA at VR = 2.5 V, per the Electrical Characteristics table on page 3 of the T4-LDS-0288 datasheet. This low leakage ensures minimal loading in high-impedance reference networks and preserves accuracy in precision analog circuits using the 1N752.
Does the 1N752 have radiation hardness certification?
Yes, the 1N752 is inherently radiation hard as documented in Microsemi MicroNote 050, and its JANTXV qualification per MIL-PRF-19500/127 confirms suitability for total ionizing dose (TID) and single-event effect (SEE) environments. Radiation performance data is validated for space and nuclear applications where the 1N752 serves as a trusted reference element.
What package type does the 1N752 use?
The 1N752 uses the DO-35 (DO-204AH) hermetically sealed axial-leaded glass package, with cathode identified by a band. Dimensions conform to JEDEC standards, including 0.055–0.090 inch body diameter and 1.000–1.500 inch lead length, and terminals are tin-lead or RoHS-compliant matte-tin plated per MIL-STD-750.
