Product details
Overview
1N4759APE3/TR8 from Microsemi is a 1.0 W, 62 V ±5% axial-lead Zener diode in DO-41 plastic package, with maximum dynamic impedance of 125 Ω at 4.0 mA test current, 5 μA reverse leakage at 47.1 V, and 2000 mA maximum surge current. It regulates voltage in power supply reference and overvoltage protection circuits across -65°C to +150°C.
For engineers reviewing the 1N4759APE3/TR8 datasheet, 1N4759APE3/TR8 pinout, 1N4759APE3/TR8 application, or 1N4759APE3/TR8 equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (45°C/W junction-to-lead), RoHS-compliant matte-tin plating, tape-and-reel packaging (TR8), and JEDEC-registered 1N4759A series compliance.
Technical Context
This discrete Zener diode operates in reverse breakdown to maintain stable 62 V regulation across wide current (4.0–2000 mA) and temperature (-65°C to +150°C) ranges. 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 precision voltage reference and clamping, it features 0.25 A maximum regulator current at 50°C ambient, 1.2 V forward voltage at 200 mA, and 14 Ω knee impedance at 0.25 mA test current - enabling reliable operation in low-noise analog rails and transient-suppression paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V ±5% at 4.0 mA - defines nominal regulation point with tight tolerance for stable reference generation |
| Power Dissipation | 1.0 W at 25°C lead temperature - sets maximum continuous DC power handling before thermal derating |
| Dynamic Impedance (ZZT) | 125 Ω at IZT = 4.0 mA - determines output voltage variation under load transients |
| Reverse Leakage Current | 5 μA at VR = 47.1 V - ensures minimal quiescent current in standby clamping applications |
| Surge Current (ISM) | 2000 mA (½-sine, 1/120 s) - supports transient overvoltage absorption without failure |
| Thermal Resistance | 45°C/W junction-to-lead (3/8″ lead length) - enables accurate thermal design in through-hole PCB layouts |
| Operating Temperature | -65°C to +150°C - qualifies for industrial, automotive, and aerospace environments with no derating below -55°C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4759A | No "e3" RoHS suffix; Sn/Pb plating; same VZ, ZZT, IZM, package | Not compliant with RoHS Directive 2011/65/EU; requires leaded assembly process | Select when legacy Sn/Pb soldering is mandated and environmental compliance is not required |
| MMSZ4708T1G | Surface-mount SOD-123 package; 62 V ±5%; 500 mW rating; 100 Ω ZZT @ 1 mA | Lower power (0.5 W), smaller footprint, higher ZZT; unsuitable for >500 mW continuous dissipation | Select for space-constrained PCBs where thermal budget allows reduced power handling |
Compared with 1N4759A (leaded) and MMSZ4708T1G (SMT), the 1N4759APE3/TR8 uniquely combines RoHS compliance, 1.0 W power, DO-41 mechanical robustness, and tape-and-reel automation readiness - making it optimal for high-reliability through-hole production requiring regulatory and logistical alignment.

FAQ
What is the Zener voltage tolerance of the 1N4759APE3/TR8?
The 1N4759APE3/TR8 has a Zener voltage tolerance of ±5%, as indicated by the "A" suffix in its JEDEC part number. This means its nominal 62 V regulation point falls within 58.9 V to 65.1 V at 4.0 mA test current and 25°C lead temperature, per Microsemi's registered electrical characteristics table.
Does the 1N4759APE3/TR8 require dry packing before PCB assembly?
No, the 1N4759APE3/TR8 does not require dry packing. It is moisture-sensitive per IPC/JEDEC J-STD-020B Level 1, meaning it has unlimited floor life and may be stored and assembled without baking or humidity-controlled handling - simplifying manufacturing logistics.
What is the maximum continuous regulator current for the 1N4759APE3/TR8 at 50°C ambient?
The maximum continuous regulator current (IZM) for the 1N4759APE3/TR8 is 2000 mA at TL < 105°C (3/8″ from body) or TA < 45°C on FR4. At 50°C ambient, derating applies: per Figure 1, power drops to ~0.92 W, limiting IZM to approximately 14.8 mA at 62 V - consistent with its 0.25 A rating at 50°C specified in the Electrical Characteristics table.
Is the 1N4759APE3/TR8 compatible with lead-free reflow processes?
Yes, the 1N4759APE3/TR8 features RoHS-compliant annealed matte-tin plating and is rated for solder temperatures up to 260°C for 10 seconds, meeting IPC-J-STD-020 requirements for lead-free reflow. Its DO-41 package withstands thermal cycling without delamination or plating degradation.
How does the "TR8" suffix affect packaging and handling of the 1N4759APE3/TR8?
The "TR8" suffix indicates EIA-296 standard tape-and-reel packaging with 8 mm carrier tape width and 1000 units per reel. This enables direct integration into automated pick-and-place equipment for through-hole insertion, reducing manual handling and improving line efficiency in high-volume production.
