Product details
Overview
1N4753A-T50A from ON Semiconductor is a 36 V, 1 W Zener diode in DO-41 glass package with ±5% tolerance, 7 Ω dynamic impedance at 36 mA test current, and 0.25 μA leakage at 27.4 V reverse voltage. It provides precise voltage regulation for power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N4753A-T50A datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage accuracy, thermal derating capability (6.67 mW/°C above 50°C), junction temperature range (–65°C to +200°C), and non-repetitive peak reverse surge rating (125 A).
Technical Context
This device operates as a silicon planar Zener diode optimized for stable DC voltage regulation under reverse-biased conditions. Its 36 V nominal Zener voltage is specified at 36 mA test current, with typical dynamic impedance of 7 Ω and maximum 12.5 Ω at that condition.
The 1N4753A-T50A features a DO-41 axial leaded glass package rated for 1.0 W power dissipation at ≤50°C lead temperature, with linear thermal derating beyond that point. It supports operation across –65°C to +200°C junction and storage temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V nominal, min 34.2 V / max 37.8 V at 36 mA - defines regulated output voltage under design load |
| Power Dissipation (PD) | 1.0 W @ TL ≤ 50°C - sets maximum continuous power handling before thermal derating |
| Zener Impedance (ZZ) | 7 Ω typical @ IZ = 36 mA - determines regulation stiffness and output voltage variation under load changes |
| Leakage Current (IR) | 0.25 μA max @ VR = 27.4 V - ensures minimal standby current in high-impedance bias networks |
| Operating Temperature | –65°C to +200°C - enables use in automotive under-hood, industrial, and aerospace environments |
| Thermal Derating | 6.67 mW/°C above 50°C - requires heatsinking or derated power in high-ambient applications |
| Non-Repetitive Peak Surge | 125 A @ 8.3 ms - supports transient overvoltage clamping without failure |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-side connection | Connected to circuit ground or lower potential node in reverse-bias regulation configuration |
| Cathode | Zener breakdown terminal / high-side connection | Connected to unregulated input; reverse voltage applied here to achieve 36 V regulation at anode |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4753A-TP | Same electrical specs; tape-and-reel packaging instead of ammo pack; identical DO-41 package and marking | No functional difference; selected for automated SMT placement compatibility | Choose 1N4753A-TP when using pick-and-place equipment requiring reel-fed components |
| BZX55-C36 | 36 V Zener, ±5% tolerance, but 500 mW rating and DO-35 package; higher ZZ (15 Ω typical) | Lower power handling and less stable regulation under varying load; unsuitable for 1 W continuous use | Select BZX55-C36 only for low-power signal-level referencing where 1 W dissipation is unnecessary |
Compared with 1N4753A-T50A, the 1N4753A-TP offers identical electrical performance with packaging optimized for automation, while BZX55-C36 trades power capability and regulation precision for smaller size and lower cost in sub-500 mW applications.

FAQ
What is the Zener voltage tolerance for 1N4753A-T50A?
The 1N4753A-T50A has a Zener voltage tolerance of ±5%, meaning its actual breakdown voltage falls between 34.2 V and 37.8 V when measured at the specified 36 mA test current and 25°C ambient. This tolerance is guaranteed per ON Semiconductor's 1N4728A–1N4758A datasheet Rev. 8, and applies directly to the 1N4753A-T50A variant.
Can 1N4753A-T50A be used in surface-mount designs?
No - the 1N4753A-T50A uses a DO-41 axial-leaded glass package intended for through-hole mounting. It is not compatible with standard SMT reflow processes. For surface-mount equivalents, consider SOD-123 or SOD-323 packaged Zeners such as MMBZ5245B, but note these differ in power rating, impedance, and voltage tolerance versus the 1N4753A-T50A.
What is the maximum allowable junction temperature for 1N4753A-T50A?
The 1N4753A-T50A has a maximum junction temperature (TJ) of +200°C, with a minimum of –65°C. This wide range allows operation in harsh environments such as engine compartments or industrial motor drives. Thermal design must ensure the junction does not exceed this limit under worst-case power dissipation and ambient conditions.
How does the 1N4753A-T50A compare to 1N4753A-TP?
The 1N4753A-T50A and 1N4753A-TP share identical electrical specifications, DO-41 package, and marking. The only difference is packaging format: T50A denotes 50-piece ammo pack, while TP indicates tape-and-reel. Both are electrically interchangeable; selection depends solely on assembly method - hand-soldering or automated placement.
Is the 1N4753A-T50A RoHS compliant?
Yes - the 1N4753A-T50A meets RoHS Directive 2011/65/EU requirements as confirmed by ON Semiconductor's official compliance documentation. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and is suitable for environmentally regulated electronics manufacturing.
