Product details
Overview
1N4760P/TR12 from Microsemi is a 1 W, 68 V ±5% axial-lead silicon Zener diode in DO-41 plastic package, designed for precision voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation across industrial and embedded systems.
For engineers reviewing the 1N4760P/TR12 datasheet, 1N4760P/TR12 pinout, 1N4760P/TR12 application, or 1N4760P/TR12 equivalent, key selection criteria include its 68 V nominal Zener voltage at 3.7 mA test current, 150 Ω dynamic impedance, 0.25 mA maximum reverse leakage at 51.7 V, 2000 mA surge current rating, and DO-41 mechanical compatibility with standard through-hole PCB layouts.
Technical Context
This Zener operates in reverse breakdown to maintain stable output voltage under varying load and temperature conditions. Its 68 V regulation point is specified at 3.7 mA test current (IZT), with dynamic impedance measured at 150 Ω - indicating moderate regulation sharpness suitable for non-critical reference and clamping roles.
The device features a thermal resistance of 45 °C/W junction-to-lead (at 10 mm lead length) and 105 °C/W junction-to-ambient on FR4 board, enabling reliable 1 W dissipation up to 105 °C lead temperature or 45 °C ambient - critical for thermally constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Vz) | 68 V ±5% at IZT = 3.7 mA - defines primary regulation setpoint for feedback or clamp circuits |
| Power Dissipation | 1.0 W at TL < 105 °C - sets maximum continuous thermal load without derating |
| Dynamic Impedance (ZZT) | 150 Ω at IZT - quantifies voltage variation per mA change in Zener current |
| Reverse Leakage (IR) | 0.25 mA max at VR = 51.7 V - determines minimum holding current for stable regulation |
| Surge Current (ISM) | 2000 mA (½-sine, 1/120 s) - supports transient overvoltage suppression capability |
| Operating Temp Range | –65 °C to +150 °C - enables deployment in extended industrial and automotive environments |
| Forward Voltage (VF) | 1.2 V max at IF = 200 mA - relevant for forward-biased protection or polarity-check use cases |
Pinout & Package
DO-41 (DO-204AL) plastic axial-lead package with cathode indicated by 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 during Zener operation; forward conduction path when biased positively |
| Cathode | Banded end | Connected to higher-potential node during regulation; defines Zener breakdown polarity and voltage reference polarity |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered 1N4760A series | Ensures standardized electrical behavior and mechanical interchangeability across qualified suppliers |
| Plastic encapsulation (P suffix) | Delivers lower thermal resistance vs. glass-body variants, improving power handling in compact layouts |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints for SMT assembly prep |
| Nonsensitive to ESD | Withstands MIL-STD-750 Method 1020 testing - reduces handling precautions in production |
| Tape-and-reel packaging (TR12) | Enables automated pick-and-place insertion; TR12 denotes EIA-296 compliant 12 mm tape width |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp Circuit |
|---|---|
Use Scenario: Regulates output voltage in isolated flyback or forward converter feedback paths using optocoupler-coupled error amplification. IC Role / Device Role / Timing Role: Zener reference element setting precise threshold for TL431 or similar shunt regulator input. Use Value: 68 V breakdown enables direct sensing of high-side secondary outputs without resistive divider scaling loss. | Use Scenario: Limits transient voltage spikes on DC bus lines caused by inductive switching or lightning-induced surges. IC Role / Device Role / Timing Role: Passive clamping device absorbing energy during overvoltage events before downstream ICs reach destructive thresholds. Use Value: 2000 mA surge rating supports robust protection against 100 A/μs transients in motor drive or relay coil snubbing. |
| Programmable Voltage Reference | Industrial Sensor Excitation |
Use Scenario: Provides stable excitation voltage for precision bridge sensors (e.g., strain gauges, RTDs) in data acquisition modules. IC Role / Device Role / Timing Role: Low-drift, low-noise voltage source replacing more complex IC references where cost and simplicity are prioritized. Use Value: ±5% tolerance and 150 Ω impedance allow calibration compensation in firmware, reducing BOM count. | Use Scenario: Supplies regulated bias to analog front-end circuitry in programmable logic controllers (PLCs) operating in noisy factory environments. IC Role / Device Role / Timing Role: Local voltage stabilizer decoupling sensitive analog sections from shared 24 V rail fluctuations. Use Value: –65 °C to +150 °C operating range ensures reliability in uncontrolled cabinet temperatures and thermal cycling. |
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 | Lacks automated assembly support; requires manual or vibratory feeding | Select 1N4760P/TR12 for SMT line integration; choose 1N4760A for prototyping or low-volume hand-soldering |
| MMBZ5260BS | SOT-23 surface-mount package; 68 V ±5%; 250 mW rating; 100 Ω ZZT | Lower power handling and different thermal profile; unsuitable for >250 mW continuous loads | Choose MMBZ5260BS only when board space is constrained and power demand stays below 250 mW |
Compared with 1N4760A and MMBZ5260BS, the 1N4760P/TR12 uniquely combines 1 W power capability, DO-41 through-hole mechanical robustness, and EIA-296 tape-and-reel readiness - making it optimal for high-reliability industrial power supplies requiring both thermal margin and automated manufacturing support.

FAQ
What is the Zener voltage tolerance of the 1N4760P/TR12?
The 1N4760P/TR12 has a nominal Zener voltage of 68 V with a ±5% tolerance, as indicated by the "A" suffix in its JEDEC designation. This means the actual breakdown voltage falls between 64.6 V and 71.4 V when measured at 3.7 mA test current and 25 °C lead temperature. The tolerance is guaranteed per JEDEC specification and applies across the full operating temperature range.
Does the 1N4760P/TR12 require dry packing before PCB assembly?
No, the 1N4760P/TR12 does not require dry packing. It is moisture sensitivity level (MSL) 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions without baking or humidity-controlled packaging. This simplifies handling and eliminates floor-life tracking for assembly operations.
What is the maximum surge current rating for the 1N4760P/TR12?
The 1N4760P/TR12 is rated for a maximum surge current (ISM) of 2000 mA, measured using a ½-sine wave pulse of 1/120 second duration at 25 °C ambient. This rating supports transient suppression in applications like relay coil snubbing or input-stage overvoltage clamping where short-duration energy spikes occur.
Can the 1N4760P/TR12 be used in surface-mount designs?
No, the 1N4760P/TR12 uses a DO-41 axial-lead package and is not suitable for surface-mount assembly. For SMT equivalents, consider Microsemi's SMAJ4760A or MLL4760A - both are surface-mount Zeners with identical 68 V ±5% regulation but different thermal and mechanical characteristics.
What does the "TR12" suffix mean in 1N4760P/TR12?
The "TR12" suffix indicates EIA-296 compliant tape-and-reel packaging with 12 mm carrier tape width, optimized for automated pick-and-place equipment. It confirms the 1N4760P/TR12 is supplied in reels compatible with standard SMT feeders, supporting high-volume manufacturing without manual handling or repackaging.
