Product details
Overview
1N4760CPE3/TR12 from Microsemi is a 68 V, ±2% tolerance, 1 W plastic-encapsulated Zener diode in DO-41 package, rated for 3.7 mA test current, 13 Ω dynamic impedance at IZT, and 51.7 V minimum regulation voltage at IZM. It delivers stable voltage reference in power supply feedback loops, overvoltage clamping circuits, and precision bias networks across industrial control and instrumentation systems.
For engineers reviewing the 1N4760CPE3/TR12 datasheet, 1N4760CPE3/TR12 pinout, 1N4760CPE3/TR12 application, or 1N4760CPE3/TR12 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (45 °C/W junction-to-lead), surge current rating (2000 mA), operating temperature range (–65 °C to +150 °C), and RoHS-compliant matte-tin plating.
Technical Context
This device operates in reverse breakdown mode with sharp knee characteristics verified per MicroNote 202, using 10% RMS AC superimposed on DC test current to measure Zener impedance. Its regulation stability is maintained across –65 °C to +150 °C ambient, with thermal derating beginning at 105 °C lead temperature or 45 °C board temperature.
The 1N4760CPE3/TR12 uses void-free UL94V-0 thermosetting epoxy encapsulation and features cathode band polarity marking. It meets MIL-STD-750 Method 1020 for ESD insensitivity and IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 68 V ±2% - precise reference for feedback networks requiring tight regulation accuracy |
| Test Current (IZT) | 3.7 mA - defines nominal operating point where VZ and ZZT are specified |
| Dynamic Impedance (ZZT) | 150 Ω @ IZT - low impedance ensures minimal output voltage variation under load transients |
| Max Regulator Current (IZM) | 65 mA @ TA = 50 °C - maximum continuous DC current before thermal runaway |
| Power Dissipation | 1.0 W @ TL < 105 °C (3/8″ lead length) - sets PCB copper pad and trace requirements for thermal management |
| Reverse Surge Current (ISM) | 2000 mA - withstands short-duration overvoltage events without degradation |
| Operating Temperature | –65 °C to +150 °C - supports deployment in extended-temperature industrial and aerospace environments |
Pinout & Package
Package: DO-41 (DO-204AL) axial-leaded plastic case, 0.7 g weight, UL94V-0 compliant epoxy body, cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node in shunt regulator configuration | Connected to system ground or lower-potential rail; reverse-biased operation requires cathode at higher potential |
| Cathode | Zener regulation terminal | Banded end; must be held at least 68 V above anode to enter breakdown; carries full regulator current |
Key Features
| Feature | Design Value |
|---|---|
| ±2% Zener voltage tolerance (C suffix) | Enables tighter feedback loop error budgets versus standard ±5% (A) or ±10% (no suffix) parts |
| RoHS-compliant matte-tin plating (e3 suffix) | Meets lead-free assembly requirements without sacrificing solderability or corrosion resistance |
| Level 1 moisture sensitivity (J-STD-020B) | Eliminates pre-bake requirement during SMT reflow, reducing manufacturing cost and cycle time |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Reduces handling precautions and eliminates need for ESD-protected workstations in production |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Used in TL431-based or discrete op-amp feedback networks to regulate +12 V or +24 V DC outputs. IC Role / Device Role / Timing Role: Shunt reference diode providing precise 68 V threshold for error amplifier comparison. Use Value: ±2% tolerance ensures output voltage stays within ±0.5% of nominal under line/load variations. | Use Scenario: Placed across motor driver H-bridge outputs or relay coils to suppress inductive kickback spikes. IC Role / Device Role / Timing Role: Transient voltage clamp limiting peak reverse voltage to 68 V. Use Value: 2000 mA surge rating absorbs 100 ms pulses without parametric shift or failure. |

IC Role / Device Role / Timing Role: Precision voltage reference establishing common-mode level for instrumentation amplifiers. Use Value: Low 150 Ω ZZT minimizes drift due to current-source loading variations across temperature. | Use Scenario: Paired with DACs or potentiometers to generate adjustable 5–60 V calibration references in test equipment. IC Role / Device Role / Timing Role: Fixed-voltage anchor point enabling ratiometric scaling of variable resistive dividers. Use Value: 68 V nominal value allows wide-range programmability while maintaining headroom for margin and noise rejection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4760A | Same 68 V nominal, but ±5% tolerance (A suffix) instead of ±2% | Acceptable where feedback loop gain compensates for wider voltage spread | Select when cost sensitivity outweighs precision requirement |
| BZX85C68 | 68 V ±5%, 1.3 W power rating, DO-41 package, different ZZT (120 Ω) | Higher power margin but looser tolerance; not RoHS e3-compliant by default | Choose for legacy designs requiring higher surge margin without redesign |
Compared with 1N4760A and BZX85C68, the 1N4760CPE3/TR12 offers superior voltage accuracy (±2%) and guaranteed RoHS compliance, making it optimal for new industrial designs demanding long-term supply continuity and regulatory alignment-without requiring layout changes.

FAQ
What is the Zener voltage tolerance of the 1N4760CPE3/TR12?
The 1N4760CPE3/TR12 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its nominal 68 V breakdown voltage is guaranteed between 66.64 V and 69.36 V at 3.7 mA test current and 25 °C lead temperature. This tighter tolerance supports precision feedback and reference applications where standard ±5% devices would introduce unacceptable error margins.
Does the 1N4760CPE3/TR12 require dry packing before PCB assembly?
No, the 1N4760CPE3/TR12 does not require dry packing. It is classified as Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions without baking prior to reflow soldering. This simplifies inventory handling and eliminates pre-assembly bake cycles, reducing manufacturing overhead and risk of thermal damage.
What is the maximum steady-state power dissipation for the 1N4760CPE3/TR12?
The 1N4760CPE3/TR12 is rated for 1.0 W steady-state power dissipation at a lead temperature (TL) below 105 °C with 3/8″ (10 mm) lead length from the body, or at ambient temperature (TA) below 45 °C when mounted on FR4 with specified copper pads and traces. Derating is required above these temperatures per Figure 1 in the Microsemi datasheet.
Is the 1N4760CPE3/TR12 compatible with lead-free reflow processes?
Yes, the 1N4760CPE3/TR12 is fully compatible with lead-free reflow. Its "e3" suffix indicates RoHS-compliant annealed matte-tin plating, qualified for soldering at 260 °C for up to 10 seconds. The UL94V-0 epoxy body withstands repeated thermal excursions without delamination or cracking, ensuring reliability in modern Pb-free assembly lines.
How is polarity marked on the 1N4760CPE3/TR12?
The 1N4760CPE3/TR12 uses a cathode band to indicate polarity: the banded end is the cathode and must be connected to the higher-potential node in Zener regulation mode. When used as a shunt regulator, the cathode connects to the voltage rail being regulated, and the anode connects to ground or the return path. Reverse connection prevents breakdown and renders the device nonfunctional as a Zener.
