Product details
Overview
1N4753CP/TR8 from Microsemi is a 1.0 W axial-lead silicon Zener diode with nominal zener voltage 36 V, ±5% tolerance (A suffix), 7.0 mA test current (IZT), 50 Ω dynamic impedance (ZZT), and 0.25 mA maximum reverse leakage at 27.4 V. It regulates voltage in power supply reference and overvoltage protection circuits across -65°C to +150°C.
For engineers reviewing the 1N4753CP/TR8 datasheet, 1N4753CP/TR8 pinout, 1N4753CP/TR8 application, or 1N4753CP/TR8 equivalent, key selection factors include its DO-41 package thermal resistance (45°C/W junction-to-lead), 1.2 V forward voltage at 200 mA, RoHS-compliant "e3" plating, and tape-and-reel packaging (TR8) for automated assembly.
Technical Context
This Zener operates in reverse breakdown to maintain stable voltage under varying load and temperature. Its 36 V nominal regulation is specified at 7.0 mA IZT with 50 Ω dynamic impedance, ensuring predictable clamping behavior in feedback loops and voltage references.
The device uses a plastic DO-41 (DO-204AL) package with cathode band marking, tin-lead or matte-tin plating, and UL94V-0 epoxy body. Thermal performance is defined at 3/8" lead length (45°C/W) and on FR4 PCB (105°C/W), supporting reliable operation in industrial power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Vz) | 36 V ±5% at 7.0 mA - defines precise regulation point for reference design |
| Power Dissipation | 1.0 W at 25°C - sets maximum continuous DC power before thermal derating |
| Dynamic Impedance (ZZT) | 50 Ω at IZT - determines output voltage variation under load current changes |
| Reverse Leakage (IR) | 0.25 μA max at 27.4 V - ensures low standby current in high-impedance bias networks |
| Forward Voltage (VF) | 1.2 V max at 200 mA - relevant for polarity-check or series-diode protection use cases |
| Operating Temperature | -65°C to +150°C - supports deployment in automotive engine bays and industrial controls |
| Thermal Resistance | 45°C/W junction-to-lead - enables accurate thermal modeling with standard lead-mounting practices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4753A | No TR8 tape-and-reel; bulk or ammo-pack only; same electrical specs and DO-41 package | Lacks automated assembly support; suitable for hand-solder or low-volume prototyping | Select 1N4753CP/TR8 when production requires reel-fed placement; choose 1N4753A for lab evaluation or small-batch builds |
| MMBZ5245BS-7-F | Surface-mount SOD-123 package; 36 V ±5%; 0.2 W rating; 100 Ω ZZT; different thermal profile | Not drop-in replaceable; requires PCB redesign; better suited for space-constrained, high-density boards | Choose MMBZ5245BS-7-F only when board area is critical and power dissipation ≤200 mW suffices |
Compared with 1N4753A and MMBZ5245BS-7-F, the 1N4753CP/TR8 uniquely combines 1.0 W power handling, DO-41 mechanical robustness, and TR8 automation readiness-making it optimal for industrial power supply and protection modules requiring field-proven reliability and volume manufacturability.

FAQ
What is the zener voltage tolerance of the 1N4753CP/TR8?
The 1N4753CP/TR8 has a nominal zener voltage of 36 V with ±5% tolerance, as indicated by the "A" suffix in the part number per Microsemi's documentation. This tolerance applies at 7.0 mA test current and 25°C lead temperature. The actual measured Vz falls between 34.2 V and 37.8 V under those conditions, and remains stable across its rated operating temperature range.
Does the 1N4753CP/TR8 have RoHS compliance certification?
Yes, the 1N4753CP/TR8 is RoHS compliant, confirmed by the "e3" suffix in its full designation. This indicates annealed matte-tin terminal plating meeting EU RoHS Directive 2011/65/EU requirements. The device contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and is suitable for environmentally regulated production environments.
What does the "TR8" suffix mean in 1N4753CP/TR8?
The "TR8" suffix denotes tape-and-reel packaging per EIA-296 standard, with 8 mm carrier tape width and 1,000 units per reel. This configuration enables direct integration into automated SMT assembly lines using standard pick-and-place equipment. The TR8 format preserves the DO-41 axial-lead mechanical form while supporting high-volume manufacturing throughput and inventory control.
Can the 1N4753CP/TR8 replace a glass-body 1N4753G in existing designs?
The 1N4753CP/TR8 is electrically identical to the glass-body 1N4753G but features a plastic DO-41 package with lower thermal resistance (45°C/W vs. ~60°C/W for glass). Mechanical mounting differs: plastic body allows tighter bend radii and higher moisture resistance (MSL Level 1), but lead spacing and overall dimensions remain JEDEC-compatible. No PCB change is needed, though thermal performance improves.
What is the maximum surge current rating for the 1N4753CP/TR8?
The 1N4753CP/TR8 has a maximum non-repetitive surge current (ISM) of 125 mA, measured using a ½ sine-wave pulse of 1/120 second duration at 25°C ambient. This rating applies to transient overvoltage events such as ESD or inductive kickback. Sustained operation above 125 mA will cause irreversible junction damage; proper series limiting resistance must be selected to keep peak surge current within this limit.
