Product details
Overview
1N4760PE3/TR8 from Microsemi is a 1.0 W, 68 V ±5% axial-lead Zener diode in DO-41 (DO-204AL) plastic package, rated for 3.7 mA test current, 150 Ω dynamic impedance at IZT, and 2000 mA maximum regulator current at TL = 50°C. It delivers stable voltage regulation in power supply reference, overvoltage protection, and biasing circuits across industrial temperature range.
For engineers reviewing the 1N4760PE3/TR8 datasheet, 1N4760PE3/TR8 pinout, 1N4760PE3/TR8 application, or 1N4760PE3/TR8 equivalent, key selection criteria include its 68 V nominal Zener voltage with ±5% tolerance, 1.0 W steady-state power rating at TL < 105°C, RoHS-compliant matte-tin plating, and EIA-296 tape-and-reel packaging (TR8 suffix).
Technical Context
This device operates in reverse breakdown to maintain a stable 68 V reference across a wide current range (IZK = 0.25 mA to IZM = 2000 mA), with thermal resistance of 45°C/W junction-to-lead at 10 mm lead length. Its Zener knee impedance is 13 Ω at 0.25 mA, supporting low-current precision regulation.
The 1N4760PE3/TR8 features moisture sensitivity Level 1 per J-STD-020B (no dry pack required), UL94V-0 epoxy case, and cathode band polarity marking. It is rated for -65°C to +150°C operating/storage temperature and withstands 260°C soldering for 10 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 68 V ±5% at IZT = 3.7 mA - defines precise regulation point for reference and clamp circuits |
| Power Dissipation | 1.0 W at TL < 105°C (3/8″ lead length) - sets maximum continuous thermal load on PCB layout |
| Dynamic Impedance (ZZT) | 150 Ω at IZT = 3.7 mA - determines output voltage variation under load transients |
| Max Regulator Current (IZM) | 2000 mA at TL = 50°C - defines peak safe conduction capability before thermal runaway |
| Knee Impedance (ZZK) | 13 Ω at IZK = 0.25 mA - enables stable regulation even at microamp-level bias currents |
| Reverse Leakage (IR) | <5 μA at VR = 51.7 V - ensures minimal quiescent current in standby protection circuits |
| Forward Voltage | ≤1.2 V at IF = 200 mA - supports use as forward-biased clamp or surge limiter in dual-role designs |
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 "P" (plastic) or "e3" (RoHS) suffix; glass-body construction; Sn/Pb plating | Higher thermal resistance (≈60°C/W); not RoHS-compliant; requires dry pack (MSL 2) | Select when legacy Sn/Pb assembly or MIL-PRF-19500 screening (e.g., JANTXV prefix) is required |
| MMSZ4708T1G | Surface-mount SOD-123 package; 68 V ±5%; 500 mW rating; 100 Ω ZZT | Lower power handling (500 mW vs. 1.0 W); smaller footprint; higher ZZT degrades regulation under load | Select for space-constrained PCBs where full 1 W dissipation is not needed and reflow compatibility is prioritized |
Compared with 1N4760A and MMSZ4708T1G, the 1N4760PE3/TR8 uniquely combines 1.0 W axial-lead power handling, RoHS compliance, MSL Level 1 reliability, and DO-41 manufacturability-making it optimal for industrial power supplies requiring field-proven robustness and automated tape-fed assembly.

FAQ
What is the Zener voltage tolerance of the 1N4760PE3/TR8?
The 1N4760PE3/TR8 has a nominal Zener voltage of 68 V with ±5% tolerance, as indicated by the "A" suffix in its base part number (1N4760A). This tolerance applies at 3.7 mA test current and 25°C lead temperature, ensuring predictable regulation across production lots and operating conditions.
Does the 1N4760PE3/TR8 require dry packing before PCB assembly?
No, the 1N4760PE3/TR8 is moisture sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored and assembled without dry pack or baking. Its void-free UL94V-0 epoxy body and RoHS-compliant matte-tin plating eliminate moisture absorption concerns during standard SMT or through-hole reflow processes.
What is the maximum allowable surge current for the 1N4760PE3/TR8?
The 1N4760PE3/TR8 supports a maximum 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 1N4760PE3/TR8 affect PCB layout?
The 1N4760PE3/TR8 has a junction-to-lead thermal resistance of 45°C/W at 10 mm lead length. To maintain 1.0 W power dissipation, PCB traces must provide adequate copper area (e.g., 4 mm² pads) and minimize thermal isolation-otherwise derating below 1.0 W is required per the published power derating curve.
Is the 1N4760PE3/TR8 compatible with lead-free soldering processes?
Yes, the 1N4760PE3/TR8 features RoHS-compliant annealed matte-tin plating qualified per MIL-STD-750 Method 2026 and rated for 260°C for 10 seconds-fully compatible with standard lead-free reflow profiles including SAC305 and SN100C alloys.
