Product details
Overview
1N752C/TR from Microsemi is a 5.6 V, ±2% tolerance, 500 mW axial-leaded silicon Zener diode in DO-35 (DO-204AH) glass package, qualified to JANTX level per MIL-PRF-19500/127, used for precision voltage regulation in power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N752C/TR datasheet, 1N752C/TR pinout, 1N752C/TR application, or 1N752C/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (8 Ω @ 50 mA), temperature coefficient (–0.028 / +0.036 %/°C), reverse leakage (5 µA @ 2.5 V), and military-grade reliability under –65°C to +175°C operation.
Technical Context
The 1N752C/TR operates as a two-terminal voltage reference device, maintaining stable 5.6 V regulation across load current variations from IZK (near knee) to IZM (70 mA), with low dynamic impedance enabling tight regulation under dynamic conditions.
Its metallurgically bonded junction ensures robust thermal stability and radiation hardness per MicroNote 050, while RoHS-compliant matte-tin plating (e3 suffix) supports lead-free assembly without compromising solderability per MIL-STD-750 method 2026.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.6 V ±2% at IZT = 50 mA - defines precise regulation setpoint for feedback loops and reference rails |
| Dynamic Impedance ZZT | 8 Ω @ IZT = 50 mA - determines output voltage variation under changing load current |
| Max Reverse Leakage IR | 5 µA @ VR = 2.5 V - ensures minimal quiescent current in standby or low-power modes |
| Power Dissipation PM(AV) | 0.5 W @ TL = 50°C (lead temp), derates linearly to zero at 175°C - sets thermal design margin for PCB layout |
| Temp Coefficient αVZ | –0.028 / +0.036 %/°C - quantifies voltage drift across industrial temperature range |
| Junction-to-Lead RθJL | 250 °C/W @ 0.375″ lead length - enables thermal modeling for heatsinking and mounting |
| Operating Temp Range | –65°C to +175°C - supports aerospace, defense, and downhole applications requiring extreme environment operation |
Pinout & Package
Hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode indicated by band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward bias; grounded or connected to lower potential in Zener mode | Provides return path for regulation current; polarity must be observed to avoid reverse breakdown failure |
| Cathode (banded end) | Regulated voltage output node in reverse-bias Zener operation | Connected to voltage rail being stabilized; band orientation critical for correct circuit functionality |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N752A/TR | ±5% tolerance (A suffix) vs. ±2% (C suffix); otherwise identical electrical and mechanical specs | Acceptable where tighter regulation not required; lower cost for non-critical references | Select 1N752A/TR only when system-level tolerance budget permits ±5% variation |
| MMBZ5232BS-7-F | Surface-mount SOD-323 package; 5.6 V ±5%; 200 mW rating; no military qualification | Used in space-constrained consumer or industrial PCBs where JANTX reliability not mandated | Choose MMBZ5232BS-7-F for high-volume automated assembly where DO-35 axial leads are impractical |
Compared with 1N752A/TR and MMBZ5232BS-7-F, the 1N752C/TR uniquely delivers ±2% regulation accuracy combined with JANTX-level military qualification and 500 mW power handling-making it irreplaceable in precision, high-reliability analog subsystems.

FAQ
What is the Zener voltage tolerance of the 1N752C/TR?
The 1N752C/TR has a nominal Zener voltage of 5.6 V with a tolerance of ±2%, as indicated by the "C" suffix in its part number per Microsemi's nomenclature standard. This tighter tolerance enables higher-accuracy voltage references compared to the ±5% 1N752A/TR variant, and is verified at IZT = 50 mA under 25°C test conditions per T4-LDS-0288 Rev. 1.
Is the 1N752C/TR suitable for surface-mount assembly?
No, the 1N752C/TR is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is designed for through-hole mounting. It does not support reflow soldering or pick-and-place automation. For surface-mount alternatives, consider the MMBZ5232BS-7-F in SOD-323, though it lacks military qualification and has ±5% tolerance.
Does the 1N752C/TR meet RoHS requirements?
Yes, the 1N752C/TR is RoHS compliant (e3 suffix), with annealed matte-tin plating on its leads. This compliance applies to the commercial-grade version only; JANTX-qualified units retain traditional tin-lead plating unless explicitly ordered with e3. Solderability is validated per MIL-STD-750 method 2026.
What is the maximum Zener current rating for the 1N752C/TR?
The 1N752C/TR has a maximum Zener current IZM of 70 mA, derived from its 500 mW power rating and 5.6 V nominal voltage (P = V × I). This rating assumes operation within thermal limits: power derates linearly from 500 mW at 50°C lead temperature to zero at 175°C, per Figure 1 in T4-LDS-0288.
How is polarity marked on the 1N752C/TR?
The 1N752C/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be connected to the higher-potential side of the circuit during Zener operation. When used as a shunt regulator, the cathode connects to the voltage rail being regulated, and the anode connects to ground or a lower reference potential.
