Product details
Overview
1N4760CP/TR12 from Microsemi is a 1.0 W axial-lead silicon Zener diode with nominal Zener voltage of 68 V, ±5% tolerance (A suffix), plastic DO-41 package, and rated for operation from –65 °C to +150 °C. It delivers stable voltage regulation in power supply reference, overvoltage protection, and voltage-clamping circuits where precise 68 V breakdown is required.
For engineers reviewing the 1N4760CP/TR12 datasheet, 1N4760CP/TR12 pinout, 1N4760CP/TR12 application, or 1N4760CP/TR12 equivalent, key selection criteria include Zener voltage (68 V), test current (3.7 mA), dynamic impedance (150 Ω), maximum regulator current (65 mA), and DO-41 thermal resistance (45 °C/W junction-to-lead).
Technical Context
This Zener operates in reverse breakdown mode with cathode band indicating polarity; regulation occurs when the banded end is held positive relative to the anode. Its 68 V nominal Zener voltage is specified at 3.7 mA test current and 25 °C lead temperature, with a typical temperature coefficient near +30 mV/°C per Figure 3.
The device exhibits 150 Ω dynamic impedance at IZT, 13 Ω knee impedance at 0.25 mA, and supports surge current up to 2000 mA (½-sine, 1/120 s). Thermal performance is defined for 3/8″ (10 mm) lead length from body (45 °C/W) or FR4 board mounting (105 °C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 68 V ±5% at 3.7 mA - defines precise clamping threshold for 68 V reference designs |
| Power Dissipation | 1.0 W at 25 °C lead temperature - sets maximum continuous DC power handling before derating |
| Dynamic Impedance (ZZT) | 150 Ω at 3.7 mA - determines output voltage variation under load current changes |
| Maximum Regulator Current (IZM) | 65 mA at TA = 50 °C - limits safe steady-state reverse current in regulation mode |
| Thermal Resistance (RθJL) | 45 °C/W junction-to-lead - enables thermal design with 3/8″ lead length mounting |
| Reverse Leakage Current | 5 μA max at 51.7 V - ensures low standby power loss below breakdown |
| Forward Voltage | 1.2 V max at 200 mA - defines conduction drop in forward-biased protection paths |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4760A | No TR12 tape-and-reel packaging; bulk or ammo pack only; identical electrical specs and DO-41 package | Lacks automated pick-and-place support; suitable for manual or low-volume prototyping | Select 1N4760CP/TR12 for SMT line integration; choose 1N4760A for bench validation or small-batch builds |
| MMBZ5260BS | SOT-23 surface-mount package; 68 V ±5%; 200 mW rating; 100 Ω ZZT; not drop-in compatible | Designed for space-constrained PCBs; unsuitable for >200 mW continuous dissipation | Choose MMBZ5260BS only when board area is critical and power <200 mW; retain 1N4760CP/TR12 for 1 W thermal robustness |

FAQ
What is the Zener voltage tolerance of the 1N4760CP/TR12?
The 1N4760CP/TR12 has a nominal Zener voltage of 68 V with ±5% tolerance, as indicated by the "A" suffix in its part number per JEDEC registration. This tolerance applies at 3.7 mA test current and 25 °C lead temperature. The "P" denotes plastic DO-41 packaging, and "TR12" specifies EIA-296 tape-and-reel packaging with 12 mm carrier tape width.
Does the 1N4760CP/TR12 require moisture preconditioning before reflow soldering?
No, the 1N4760CP/TR12 is moisture sensitivity level 1 per IPC/JEDEC J-STD-020B and does not require dry packing or baking prior to soldering. Its void-free thermosetting epoxy body and Level 1 classification allow direct placement onto PCBs without moisture-related reliability risks during standard reflow profiles.
What is the maximum surge current rating for the 1N4760CP/TR12?
The 1N4760CP/TR12 supports a maximum non-repetitive reverse surge current (ISM) of 2000 mA, measured using a ½-sine wave pulse of 1/120 second duration at 25 °C ambient. This rating enables reliable transient suppression in power rails subject to short-duration overvoltage events.
How does the thermal resistance of the 1N4760CP/TR12 affect PCB layout?
The 1N4760CP/TR12 has a junction-to-lead thermal resistance of 45 °C/W when mounted with 3/8″ (10 mm) lead length from the body. For FR4 boards, junction-to-ambient resistance is 105 °C/W with specified copper pad geometry (4 mm² pads, 1 mm track width, 25 mm length), guiding heatsinking decisions and trace width selection to maintain safe operating temperatures.
Can the 1N4760CP/TR12 be used in forward-bias applications?
Yes - the 1N4760CP/TR12 functions as a standard silicon diode in forward bias, with a maximum forward voltage of 1.2 V at 200 mA. While optimized for reverse-bias Zener regulation, it supports forward-conducting roles such as polarity protection or basic rectification in low-current auxiliary paths where 1.2 V drop is acceptable.
