Product details
Overview
1N4753CPE3/TR12 from Microsemi is a 1.0 W, 36 V ±2% tolerance silicon Zener diode in DO-41 plastic package, rated for 7.0 mA test current, 50 Ω dynamic impedance at IZT, and 1000 mA maximum regulator current at TA = 50°C. It delivers stable voltage regulation in power supply reference and overvoltage protection circuits across -65°C to +150°C.
For engineers reviewing the 1N4753CPE3/TR12 datasheet, 1N4753CPE3/TR12 pinout, 1N4753CPE3/TR12 application, or 1N4753CPE3/TR12 equivalent, key selection factors include its 2% voltage tolerance, 1W power rating at 3/8" lead length, RoHS-compliant matte-tin plating, tape-and-reel packaging (TR12), and JEDEC-registered DO-41 mechanical form factor.
Technical Context
This Zener operates in reverse breakdown to maintain a stable 36 V reference across a wide current range (IZK = 0.25 mA to IZM = 1000 mA), with sharp knee characteristics verified by dual-point Zener impedance measurement per MicroNote 202. Its thermal resistance is 45°C/W junction-to-lead (3/8" lead length) and 105°C/W junction-to-ambient on FR4 board.
The device features cathode band polarity marking, UL94V-0 void-free epoxy case, and is moisture-sensitive Level 1 per J-STD-020B-no dry pack required. It supports axial-lead mounting and withstands 260°C soldering for 10 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±2% at IZT = 7.0 mA - tight tolerance enables precision reference design without post-calibration |
| Power Dissipation | 1.0 W at TL < 105°C (3/8" lead) - defines maximum continuous DC power under standard lead-mount condition |
| Dynamic Impedance (ZZT) | 50 Ω at IZT = 7.0 mA - low AC impedance ensures minimal output voltage variation under load transients |
| Max Regulator Current (IZM) | 1000 mA at TA = 50°C - sets upper limit for sustained regulation current before thermal derating applies |
| Reverse Leakage (IR) | 5 μA max at VR = 27.4 V - confirms low off-state conduction below knee voltage |
| Thermal Resistance (RθJL) | 45°C/W junction-to-lead - enables accurate junction temperature estimation for reliability analysis |
| Operating Temperature | -65°C to +150°C - supports deployment in automotive under-hood and industrial control environments |
Pinout & Package
DO-41 (DO-204AL) plastic axial-leaded package with cathode indicated by colored 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 | Non-banded end | Connected to lower-potential node; forward voltage ≤1.2 V @ 200 mA when used as rectifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4753A | Same 36 V nominal, but ±5% tolerance (A suffix) instead of ±2% (C suffix) | Less precise regulation; requires tighter system-level tolerance budget | Select when cost sensitivity outweighs need for 2% accuracy |
| MMSZ5245B-TP | Surface-mount SOD-123 package, 36 V ±5%, 500 mW rating, 30 Ω ZZT | Lower power and smaller footprint; unsuitable for >500 mW continuous dissipation | Select for space-constrained PCBs where 1W dissipation is not required |
Compared with 1N4753A and MMSZ5245B-TP, the 1N4753CPE3/TR12 offers superior voltage accuracy and higher power handling in an axial-leaded, tape-and-reel format-ideal for through-hole production and precision analog reference designs requiring long-term stability.

FAQ
What is the Zener voltage tolerance of the 1N4753CPE3/TR12?
The 1N4753CPE3/TR12 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in the part number. This means its nominal 36 V Zener voltage is guaranteed between 35.28 V and 36.72 V when measured at 7.0 mA test current and 25°C lead temperature. This tight tolerance supports precision reference applications where calibration overhead must be minimized.
Is the 1N4753CPE3/TR12 RoHS compliant?
Yes, the 1N4753CPE3/TR12 is RoHS compliant, as confirmed by the "e3" suffix in its designation. It uses annealed matte-tin plating on leads and meets EU Directive 2011/65/EU requirements with no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE. The UL94V-0 epoxy body further supports environmentally aligned manufacturing.
What does the "TR12" suffix indicate in 1N4753CPE3/TR12?
The "TR12" suffix indicates tape-and-reel packaging per EIA-296 standard, with 12 mm tape width. This format enables automated pick-and-place insertion for axial-leaded components in high-volume production. The reel contains 10,000 units, facilitating efficient handling and reducing manual loading time compared to bulk or ammo-pack options.
What is the maximum continuous power dissipation for the 1N4753CPE3/TR12?
The 1N4753CPE3/TR12 is rated for 1.0 W continuous power dissipation at a lead temperature (TL) below 105°C with 3/8" (10 mm) lead length from the body. Derating is required above this temperature per Figure 1 in the datasheet; at 25°C ambient on FR4 board, the effective power limit drops to approximately 0.48 W due to higher junction-to-ambient thermal resistance.
How is polarity marked on the 1N4753CPE3/TR12?
The 1N4753CPE3/TR12 uses a cathode band-typically a single color ring near one end-to indicate the cathode terminal. During Zener operation, the banded end must be held at a higher potential than the anode (non-banded end) to achieve reverse-bias breakdown and regulation. Forward voltage is ≤1.2 V at 200 mA, confirming standard silicon diode behavior in forward conduction.
