Product details
Overview
1N4760APE3/TR12 from Microsemi is a 1.0 W, 68 V ±5% axial-lead silicon 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 - used for precision voltage reference and overvoltage protection in DC power supplies.
For engineers reviewing the 1N4760APE3/TR12 datasheet, 1N4760APE3/TR12 pinout, 1N4760APE3/TR12 application, or 1N4760APE3/TR12 equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (45°C/W junction-to-lead), surge current rating (2000 mA), RoHS-compliant matte-tin plating, and tape-and-reel packaging per EIA-296.
Technical Context
This device operates in reverse-bias breakdown to maintain stable 68 V regulation across 3.7 mA to 2000 mA operating current range, with temperature coefficient near +3.5 mV/°C (per Figure 3). 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.
It features cathode band polarity marking, 1.2 V max forward voltage at 200 mA, and is rated for 260°C soldering (10 s). The "e3" suffix confirms RoHS compliance; "TR12" denotes EIA-296 tape-and-reel packaging with 12 mm carrier tape width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 68 V ±5% at 3.7 mA - defines nominal regulation point with tight tolerance for stable reference generation |
| Power Dissipation | 1.0 W at TL < 105°C (3/8″ lead length) - sets maximum continuous power handling under defined thermal conditions |
| Dynamic Impedance (ZZT) | 150 Ω at IZT = 3.7 mA - indicates voltage stability under small-signal AC variations around regulation point |
| Max Regulator Current (IZM) | 2000 mA at TL = 50°C - determines peak steady-state current capability before thermal derating applies |
| Thermal Resistance | 45 °C/W junction-to-lead - enables accurate junction temperature estimation for reliability analysis in lead-mounted designs |
| Surge Current (ISM) | 2000 mA (½-sine, 1/120 s) - specifies short-duration overload capacity for transient suppression applications |
| Forward Voltage | ≤1.2 V at 200 mA - ensures low conduction loss when used in forward-biased clamping or series configurations |
Pinout & Package
Package: DO-41 (DO-204AL), axial-lead plastic molded case with void-free UL94V-0 epoxy body, cathode indicated by colored band. Terminals 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; carries full regulator current during Zener operation |
| Cathode | Banded end | Connected to higher-potential node; defines regulated output voltage referenced to anode |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered 1N4760A series | Ensures standardized electrical behavior and interchangeability across qualified suppliers |
| Plastic P-suffix construction | Delivers 45°C/W junction-to-lead thermal resistance - 30% lower than comparable glass-body (G-suffix) variants |
| RoHS-compliant e3 suffix | Confirms lead-free matte-tin plating and full compliance with EU Directive 2011/65/EU |
| Tape-and-reel TR12 packaging | Enables automated SMT placement compatibility despite axial-lead form factor via carrier tape handling |
| MIL-STD-750 ESD robustness | Rated nonsensitive per Method 1020 - eliminates need for special ESD handling in assembly |
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-T | Same 68 V ±5%, 1 W rating, but uses Pb-free matte-tin plating without "e3" designation; no tape-and-reel (TR12) packaging | Not suitable for automated assembly requiring EIA-296 carrier tape; requires manual or bulk loading | Select when RoHS compliance is required but TR12 packaging is unnecessary |
| MMSZ4707T1G | Surface-mount SOD-123 package, same 68 V ±5%, but rated 500 mW and 100 Ω ZZT; different thermal profile and surge rating | Cannot replace 1N4760APE3/TR12 in high-current (>500 mA) or high-surge applications due to lower power and ISM | Select only for space-constrained PCBs where 1 W dissipation and 2000 mA surge are not required |
Compared with 1N4760APE3/TR12, 1N4760A-T lacks RoHS documentation traceability and tape-and-reel support, while MMSZ4707T1G trades axial-lead robustness and 1 W power handling for board-space savings - neither offers drop-in replacement capability without layout or thermal redesign.

FAQ
What is the Zener voltage tolerance of the 1N4760APE3/TR12?
The 1N4760APE3/TR12 has a Zener voltage tolerance of ±5% at 3.7 mA test current, as confirmed by its "A" suffix per JEDEC registration. This means its actual regulation voltage falls between 64.6 V and 71.4 V under specified test conditions, enabling predictable performance in reference and protection circuits.
Does the 1N4760APE3/TR12 support automated assembly?
Yes, the 1N4760APE3/TR12 supports automated assembly via its "TR12" suffix, indicating EIA-296-compliant tape-and-reel packaging with 12 mm carrier tape width. This allows direct integration into pick-and-place machines, despite its axial-lead DO-41 form factor.
What is the maximum surge current rating for the 1N4760APE3/TR12?
The 1N4760APE3/TR12 has a maximum surge current (ISM) rating 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 relay-driven or inductive-load circuits without degradation.
How does the thermal resistance of the 1N4760APE3/TR12 compare to glass-body Zeners?
The 1N4760APE3/TR12 exhibits 45°C/W junction-to-lead thermal resistance - significantly lower than glass-body equivalents (typically >65°C/W) - due to its plastic P-suffix construction. This improves power handling efficiency and reduces junction temperature rise under identical mounting conditions.
Is the 1N4760APE3/TR12 compliant with RoHS directives?
Yes, the 1N4760APE3/TR12 is fully RoHS-compliant, as verified by its "e3" suffix, which designates RoHS-compliant annealed matte-tin terminal plating and adherence to EU Directive 2011/65/EU. Full compliance documentation is available through Microsemi's official product records.
