Product details
Overview
1N4760AP/TR12 from Microsemi is a 1.0 W, 68 V ±5% plastic-encapsulated Zener diode in DO-41 package, rated for 3.7 mA test current (IZT), 150 Ω dynamic impedance (ZZT), and 2000 mA maximum regulator current (IZM) at TA = 50°C. It provides stable voltage regulation in power supply reference, overvoltage protection, and voltage-clamping circuits across industrial temperature range.
For engineers reviewing the 1N4760AP/TR12 datasheet, 1N4760AP/TR12 pinout, 1N4760AP/TR12 application, or 1N4760AP/TR12 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (45 °C/W junction-to-lead), surge current rating (2000 mA), reverse leakage (5 μA @ 51.7 V), and RoHS-compliant "e3" plating option.
Technical Context
This axial-lead Zener diode operates in reverse breakdown to maintain a stable 68 V reference across a wide current range (3.7 mA to 2000 mA). Its DO-41 plastic package 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, it features a sharp knee with 13 Ω knee impedance (ZZK) at 0.25 mA test current, 1.2 V forward voltage max at 200 mA, and ±5% voltage tolerance confirmed per JEDEC registration. Operating temperature spans −65°C to +150°C with solderability validated to 260°C for 10 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 68 V ±5% at IZT = 3.7 mA - 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 under defined thermal condition |
| Dynamic Impedance (ZZT) | 150 Ω at IZT = 3.7 mA - determines AC voltage variation under small-signal ripple conditions |
| Max Regulator Current (IZM) | 2000 mA at TA = 50°C - specifies peak DC current before thermal runaway under derated ambient |
| Reverse Leakage (IR) | 5 μA max at VR = 51.7 V - ensures minimal quiescent current in standby clamping applications |
| Thermal Resistance | 45 °C/W junction-to-lead - enables accurate junction temperature estimation for reliability modeling |
| Operating Temperature | −65°C to +150°C - supports deployment in extended industrial and automotive under-hood environments |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or low-side return path during Zener regulation |
| Cathode | Regulated output node | Banded terminal; connected to input rail to clamp voltage at 68 V above anode potential |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered 1N4760A series | Ensures cross-manufacturer compatibility and standardized test methodology per industry specification |
| Plastic encapsulation (P suffix) | Delivers 45 °C/W junction-to-lead thermal resistance - 30% lower than equivalent glass-body (G) variants |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement and bake-out prior to PCB assembly per IPC/JEDEC J-STD-020B |
| RoHS-compliant "e3" option | Enables compliance with EU Directive 2011/65/EU using annealed matte-tin plating instead of Sn/Pb |
| Nonsensitive to ESD | Withstands >4 kV HBM per MIL-STD-750 Method 1020 - suitable for handling in standard assembly lines |

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; same electrical specs and DO-41 package | Not suitable for automated pick-and-place; requires manual loading or vibratory bowl feed | Select 1N4760AP/TR12 for SMT line integration; choose 1N4760A for prototyping or low-volume hand assembly |
| MMSZ4708T1G | Surface-mount SOD-123 package; 68 V ±5%; 500 mW rating; 100 Ω ZZT; 1000 mA IZM | Limited power handling and thermal mass; unsuitable for sustained 1 W dissipation or high-surge events | Use MMSZ4708T1G only in space-constrained, low-power designs where DO-41 footprint is prohibitive |
Compared with 1N4760A (bulk) and MMSZ4708T1G (SMT), the 1N4760AP/TR12 uniquely combines JEDEC-standardized 1 W capability, tape-and-reel automation support, and proven robustness in industrial transients-making it optimal for high-reliability through-hole power regulation.

FAQ
What is the Zener voltage tolerance of the 1N4760AP/TR12?
The 1N4760AP/TR12 has a nominal Zener voltage of 68 V with a ±5% tolerance, as confirmed by JEDEC registration and verified at 3.7 mA test current (IZT) under TL = 25°C conditions. This tolerance applies to all units bearing the "A" suffix and is maintained across the full operating temperature range of −65°C to +150°C.
Does the 1N4760AP/TR12 support automated assembly?
Yes, the "TR12" suffix indicates EIA-296-compliant tape-and-reel packaging optimized for pick-and-place equipment. The 1N4760AP/TR12 is supplied in 12 mm carrier tape with 1000 units per reel, enabling direct integration into high-volume SMT production lines without manual handling or repackaging.
What is the maximum surge current rating for the 1N4760AP/TR12?
The 1N4760AP/TR12 is rated for 2000 mA maximum reverse surge current (ISM), measured using a ½-sine wave pulse of 1/120 second duration at 25°C ambient. This rating supports transient suppression in industrial power rails and protects downstream circuitry from short-duration overvoltage events.
How does the thermal resistance of the 1N4760AP/TR12 compare to glass-body Zeners?
The 1N4760AP/TR12 exhibits 45 °C/W junction-to-lead thermal resistance at 3/8″ (10 mm) lead length - significantly lower than equivalent glass-body (G-suffix) versions due to superior heat conduction through its void-free thermosetting epoxy body. This improves power handling stability under continuous DC load.
Is the 1N4760AP/TR12 RoHS compliant?
Yes, the 1N4760AP/TR12 is RoHS compliant, as indicated by the "e3" designation in Microsemi's official documentation. It uses annealed matte-tin plating per MIL-STD-750 Method 2026 and conforms to EU Directive 2011/65/EU, with no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE substances above threshold limits.
