Product details
Overview
1N752C from Microsemi is a 500 mW, 5.6 V ±2% tolerance silicon Zener diode in DO-35 glass axial package, qualified to JANTX level per MIL-PRF-19500/127, with dynamic impedance of 8 Ω at 50 mA and temperature coefficient of –0.028 / +0.036 %/°C, used for precision voltage regulation in military power supply references.
For engineers reviewing the 1N752C datasheet, 1N752C pinout, 1N752C application, or 1N752C equivalent, key selection factors include its 5.6 V nominal Zener voltage, ±2% tolerance (C suffix), 8 Ω dynamic impedance at IZT = 50 mA, JANTX qualification, and DO-35 hermetic glass package with cathode band polarity marking.
Technical Context
This device operates as a two-terminal voltage reference by maintaining a stable reverse-biased breakdown voltage across its terminals under specified current conditions. It exhibits a dual-signature temperature coefficient (–0.028 / +0.036 %/°C) indicating voltage drift reversal near room temperature, and achieves 8 Ω dynamic impedance at 50 mA test current with 2.5 V reverse voltage rating.
Designed for high-reliability environments, the 1N752C features internal metallurgical bonding, non-ESD-sensitive construction per MIL-STD-750 Method 1020, and inherent radiation hardness documented in Microsemi MicroNote 050. Its thermal resistance is 250 °C/W junction-to-lead (0.375″ lead length) and 300 °C/W junction-to-ambient on PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 5.6 V at IZT = 50 mA - defines primary regulation point for reference design |
| Zener Tolerance | ±2% - tighter than standard ±5%, enabling higher-accuracy voltage references |
| Dynamic Impedance | 8 Ω at IZT = 50 mA - low impedance ensures minimal output voltage variation under load changes |
| Max Power Dissipation | 500 mW at TL = +50°C - sets maximum continuous DC power handling with linear derating to zero at 175°C |
| Temp Coefficient αVZ | –0.028 / +0.036 %/°C - bipolar drift behavior requires thermal compensation in precision circuits |
| Reverse Voltage VR | 2.5 V - maximum non-breakdown reverse bias before entering regulation region |
| Max Reverse Current IR | 5 µA at VR = 2.5 V - low leakage supports stable biasing in high-impedance networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N752A | ±5% tolerance (A suffix) vs. ±2% (C suffix); identical Zener voltage, package, and qualification level | Acceptable where system-level calibration compensates for wider tolerance band | Select 1N752A only when cost sensitivity outweighs accuracy requirements |
| 1N5232B | 5.6 V ±5% (B suffix), 500 mW, DO-35, commercial-grade only - no MIL-qualified variants available | Limited to non-military industrial designs; lacks JANTX qualification and radiation hardness | Choose 1N5232B only for cost-driven commercial applications with no environmental or reliability mandates |
Compared with 1N752A and 1N5232B, the 1N752C delivers superior voltage accuracy and certified military reliability-critical for systems where recalibration is impractical and failure consequences are severe.

FAQ
What is the Zener voltage tolerance of the 1N752C?
The 1N752C has a nominal Zener voltage of 5.6 V with a tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This tighter tolerance enables higher-accuracy voltage references compared to the ±5% 1N752A variant, and is verified under standard test conditions at 25°C with IZT = 50 mA.
Is the 1N752C qualified to military standards?
Yes, the 1N752C is qualified to JANTX level per MIL-PRF-19500/127, confirming compliance with rigorous environmental, reliability, and screening requirements for aerospace and defense applications. Its qualification includes testing across –65°C to +175°C operating temperature range and adherence to hermeticity and metallurgical bond standards.
What package type does the 1N752C use?
The 1N752C uses the DO-35 (DO-204AH) hermetically sealed axial-leaded glass package. The cathode is marked by a colored band, and leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026. Dimensions conform to JEDEC outline standards with body diameter 1.40–2.29 mm and lead length 25.40–38.10 mm.
What is the dynamic impedance of the 1N752C and why does it matter?
The 1N752C has a dynamic impedance of 8 Ω measured at IZT = 50 mA. This low value indicates minimal change in Zener voltage under varying load currents, making it suitable for precision regulation where output stability is critical-especially in analog sensor interfaces and reference dividers where ripple rejection and line regulation directly impact measurement fidelity.
Does the 1N752C have radiation hardness certification?
Yes, the 1N752C exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. While not individually tested per MIL-STD-883, its construction-including metallurgical bonding and hermetic DO-35 packaging-provides proven resilience in total ionizing dose (TID) environments typical of space and nuclear applications, supporting use in radiation-exposed instrumentation without additional shielding.
