Product details
Overview
1N4760PE3/TR12 from Microsemi is a 68 V, ±5% tolerance, 1 W axial-lead silicon Zener diode in DO-41 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 - used for precision voltage reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the 1N4760PE3/TR12 datasheet, 1N4760PE3/TR12 pinout, 1N4760PE3/TR12 application, or 1N4760PE3/TR12 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (45 °C/W junction-to-lead), surge current rating (2000 mA), RoHS compliance (e3 suffix), and tape-and-reel packaging (TR12).
Technical Context
This device operates in reverse breakdown to maintain stable 68 V regulation across a wide current range (3.7 mA to 2000 mA), with sharp knee characteristics verified by dual-point Zener impedance measurement per MicroNote 202. Its DO-41 plastic encapsulation delivers lower thermal resistance than glass-body variants and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack.
Designed for DC voltage regulation under steady-state and transient conditions, it supports operation from –65°C to +150°C, features 1.2 V max forward voltage at 200 mA, and withstands 260°C soldering for 10 s. Polarity is marked by cathode band; regulation requires cathode-positive bias relative to anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 68 V ±5% at IZT = 3.7 mA, TL = 25°C - defines nominal regulation point with tight production control |
| Power Dissipation | 1.0 W at TL < 105°C (3/8″ lead length) - sets maximum continuous DC power handling before thermal derating |
| Dynamic Impedance | 150 Ω at IZT = 3.7 mA - indicates regulation stiffness; lower values yield smaller output voltage variation under load changes |
| Max Regulator Current | 2000 mA at TL = 50°C - defines peak safe reverse current before thermal runaway or parameter shift |
| Reverse Leakage | 5 μA max at VR = 51.7 V - ensures minimal quiescent current in standby or high-impedance sensing circuits |
| Thermal Resistance | 45 °C/W junction-to-lead - enables accurate thermal design when leads serve as primary heat path |
| Surge Current | 2000 mA (½-sine, 1/120 s) - supports transient overvoltage clamping without degradation |
Pinout & Package
DO-41 (DO-204AL) plastic axial-leaded package: void-free thermosetting epoxy body (UL94V-0), tin-lead or RoHS-compliant matte-tin plating, cathode indicated by colored band, weight 0.7 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-bias operation | Connected to system ground or lower-potential rail; must be negative relative to cathode during regulation |
| Cathode | Zener voltage output terminal | Banded end; connected to regulated voltage node; polarity marking critical for correct circuit orientation |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered 1 W Zener | Fully compliant with JEDEC 1N47xxA standard - ensures cross-manufacturer interchangeability and test consistency |
| RoHS-compliant "e3" suffix | Lead-free matte-tin plating per MIL-STD-750 Method 2026 - satisfies environmental compliance without solderability compromise |
| Tape-and-reel packaging | TR12 suffix denotes EIA-296 standard reel - enables automated SMT placement despite axial-lead form factor |
| Level 1 moisture sensitivity | No dry pack required per IPC/JEDEC J-STD-020B - reduces handling cost and eliminates bake-out prior to assembly |
| Nonsensitive to ESD | Qualified per MIL-STD-750 Method 1020 - allows safe handling in standard workstations without special grounding protocols |
Applications

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, no tape-and-reel | Lacks RoHS compliance and automated assembly support; higher thermal resistance than plastic variant | Select only if legacy glass-body qualification or non-RoHS requirement applies |
| MMSZ4708T1G | Surface-mount SOD-123 package, 68 V ±5%, 500 mW rating, 300 Ω ZZT | Lower power and higher impedance limit use to low-current references; not suitable for 2000 mA surge clamping | Choose for space-constrained PCBs where 1 W dissipation is unnecessary |
Compared with 1N4760A and MMSZ4708T1G, the 1N4760PE3/TR12 uniquely combines 1 W power handling, DO-41 mechanical robustness, RoHS compliance, and EIA-296 tape-and-reel - making it optimal for industrial power supplies requiring high-reliability through-hole assembly and transient immunity.

FAQ
What is the Zener voltage tolerance of the 1N4760PE3/TR12?
The 1N4760PE3/TR12 has a nominal Zener voltage of 68 V with a ±5% tolerance, as confirmed by its "A" suffix per JEDEC registration. This tolerance is measured at TL = 25°C (+8, –2°C) with 90 s stabilization after DC current application, ensuring predictable regulation across production lots and operating conditions.
Does the 1N4760PE3/TR12 support automated assembly?
Yes - the "TR12" suffix indicates EIA-296 standard tape-and-reel packaging, enabling compatibility with pick-and-place equipment despite its axial-leaded DO-41 form factor. The RoHS-compliant matte-tin plating also ensures reliable solder wetting during reflow or wave soldering processes.
What is the maximum surge current rating for the 1N4760PE3/TR12?
The 1N4760PE3/TR12 is rated for 2000 mA maximum surge current using a ½-sine wave pulse of 1/120 second duration at 25°C ambient, as specified in the Electrical Characteristics table. This rating validates its suitability for transient overvoltage clamping in industrial and telecom power rails.
How does the thermal resistance of the 1N4760PE3/TR12 compare between lead and ambient mounting?
The 1N4760PE3/TR12 has 45 °C/W junction-to-lead thermal resistance at 3/8″ (10 mm) lead length, but rises to 105 °C/W junction-to-ambient when mounted on FR4 with 4 mm² copper pads. This difference highlights the importance of using leads as primary heat paths in high-power designs to avoid exceeding 105°C lead temperature limits.
Is the 1N4760PE3/TR12 suitable for high-reliability military applications?
While the base 1N4760PE3/TR12 is commercial-grade, Microsemi offers screened versions (e.g., with MQ, MX, MV prefixes) compliant with MIL-PRF-19500 for JAN, JANTX, JANTXV, and JANS levels. These require separate part numbers and are not implied by the TR12 suffix alone.
