Product details
Overview
1N753C/TR from Microsemi is a 500 mW, 6.2 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 3 Ω at 20 mA, maximum reverse current of 5 µA at 3.5 V, and temperature coefficient of +0.045 %/°C - used for precision voltage regulation in military power supplies and analog reference circuits.
For engineers reviewing the 1N753C/TR datasheet, 1N753C/TR pinout, 1N753C/TR application, or 1N753C/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), junction-to-lead thermal resistance (250 °C/W), RoHS compliance status, military qualification level, and DO-35 mechanical mounting compatibility.
Technical Context
This device operates as a two-terminal voltage reference by maintaining a stable 6.2 V across its terminals under reverse bias, with regulation defined at IZT = 20 mA. Its metallurgically bonded junction ensures low noise, minimal capacitance, and radiation hardness per MicroNote 050.
The 1N753C/TR exhibits positive temperature coefficient (+0.045 %/°C) above 5 V, enabling predictable drift compensation in temperature-stable references. It supports operation from –65 °C to +175 °C and is rated for 0.5 W dissipation at TL = 50 °C with 0.375-inch lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.2 V ±2% at IZT = 20 mA - defines nominal regulation point with tight tolerance for stable reference design |
| Dynamic Impedance ZZT | 3 Ω at IZT = 20 mA - low AC impedance ensures minimal output voltage variation under load transients |
| Max Reverse Current IR | 5 µA at VR = 3.5 V - low leakage preserves accuracy in high-impedance bias networks |
| Power Dissipation PM(AV) | 0.5 W at TL = 50 °C (0.375″ lead) - sets thermal design boundary for axial-leaded PCB mounting |
| Temp Coefficient αVZ | +0.045 %/°C - enables predictable voltage drift compensation in wide-temperature applications |
| Junction Temp Range | –65 °C to +175 °C - supports operation in harsh environments including aerospace and defense systems |
| Thermal Resistance RθJL | 250 °C/W - determines temperature rise per watt dissipated from junction to lead, critical for thermal derating |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded 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 | Reverse-bias current sink terminal | Connected to lower-potential node; forward conduction occurs at ~1.1 V when anode > cathode |
| Cathode | Reverse-bias voltage reference terminal | Banded end; held at regulated 6.2 V above anode during Zener breakdown; polarity critical for regulation |
Key Features
| Feature | Design Value |
|---|---|
| JANTX qualification | MIL-PRF-19500/127 certified for high-reliability military applications with full traceability and screening |
| ±2% Zener tolerance | Tighter than standard ±5% option - reduces calibration burden in precision analog references |
| Metallurgical bond construction | Enhances long-term stability and radiation hardness vs. alloyed or diffused junctions |
| Low 3 Ω dynamic impedance | Minimizes output voltage ripple under varying load currents in regulated supply rails |
| Non-ESD-sensitive | Complies with MIL-STD-750 method 1020 - eliminates need for ESD handling controls in assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N753A/TR | ±5% Zener tolerance (vs. ±2% for 1N753C/TR); otherwise identical electrical and mechanical specs | Suitable where tighter regulation not required; lower cost for non-critical biasing | Select 1N753A/TR only if system-level calibration or margin analysis confirms ±5% VZ acceptable |
| MMBZ5234B-TP | Surface-mount SOD-123 package; ±5% tolerance; 200 mW rating; different thermal profile and layout footprint | Used in compact commercial designs where DO-35 axial leads are incompatible with automated assembly | Choose MMBZ5234B-TP only when board space, reflow compatibility, and cost outweigh military qualification needs |
Compared with 1N753A/TR and MMBZ5234B-TP, the 1N753C/TR delivers tighter voltage tolerance and JANTX qualification essential for mil-spec analog references, while requiring axial through-hole assembly and higher thermal management attention due to its 500 mW rating.

FAQ
What is the Zener voltage tolerance of the 1N753C/TR?
The 1N753C/TR has a nominal Zener voltage of 6.2 V with a tolerance of ±2%, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tighter tolerance is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0288 Rev. 1, where 1N753A-1 (±5%) and 1N753C/TR are explicitly differentiated. The 1N753C/TR maintains this specification at IZT = 20 mA and TJ = 25 °C.
Is the 1N753C/TR RoHS compliant?
Yes, the 1N753C/TR is RoHS compliant, as indicated by the "e3" marking per Microsemi's nomenclature guide and confirmed in the Features section stating "RoHS compliant versions available (commercial grade only)." Although the part carries JANTX qualification, its RoHS compliance applies to the commercial-grade variant bearing the "TR" tape-and-reel suffix and "e3" marking - verified in the Mechanical and Packaging section of T4-LDS-0288.
What does the "TR" suffix mean in 1N753C/TR?
The "TR" suffix in 1N753C/TR denotes tape-and-reel packaging per EIA-296 standard, as specified in the Mechanical and Packaging section of T4-LDS-0288. This format enables automated pick-and-place assembly and is distinct from bulk or ammo-pack options. The "TR" does not affect electrical or reliability specifications - the 1N753C/TR retains full JANTX qualification, ±2% tolerance, and DO-35 package dimensions regardless of packaging format.
What is the maximum power dissipation for the 1N753C/TR?
The 1N753C/TR has an average rated power dissipation of 0.5 W at TL = +50 °C with 0.375-inch (9.53 mm) lead length from body, linearly derating to zero at +175 °C. When mounted on a PCB, it is rated for 0.4 W at TA = +55 °C, per the Maximum Ratings table on page 1 of T4-LDS-0288. These values are validated by the derating curves in Figures 1 and 2.
How is polarity marked on the 1N753C/TR?
The 1N753C/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held at a higher potential than the anode to achieve Zener regulation. This marking convention is explicitly stated in the Mechanical and Packaging section of T4-LDS-0288, which notes "Cathode indicated by band. Diode to be operated with the banded end positive with respect to the opposite end for Zener regulation."
