Product details
Overview
1N4759PE3/TR8 from Microsemi is a 1.0 W, 62 V ±5% Zener diode in DO-41 plastic package, designed for precision voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation. It delivers stable regulation across -65°C to +150°C, with 125 Ω dynamic impedance at 4.0 mA test current and 14 Ω knee impedance at 0.25 mA.
For engineers reviewing the 1N4759PE3/TR8 datasheet, 1N4759PE3/TR8 pinout, 1N4759PE3/TR8 application, or 1N4759PE3/TR8 equivalent, key selection criteria include its 62 V nominal Zener voltage, 1.0 W power rating at 25°C, DO-41 axial-leaded package, RoHS-compliant matte-tin plating, and 1000 mA maximum surge current capability.
Technical Context
This Zener operates in reverse breakdown mode with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its thermal resistance is 45°C/W junction-to-lead (3/8" lead length) and 105°C/W junction-to-ambient on FR4 board.
The device exhibits a typical temperature coefficient near +3.5 mV/°C (per Figure 3), confirming positive drift above ~50 V, and maintains regulation stability under steady-state currents from 0.25 mA to 700 mA, with specified knee behavior at IZK = 0.25 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Vz) | 62 V ±5% at IZT = 4.0 mA - defines precise regulation point for feedback and clamp circuits |
| Power Dissipation | 1.0 W at TL ≤ 105°C (3/8" lead length) - sets maximum continuous thermal load without derating |
| Dynamic Impedance (ZZT) | 125 Ω at IZT = 4.0 mA - determines output voltage variation under load transients |
| Knee Impedance (ZZK) | 14 Ω at IZK = 0.25 mA - ensures stable low-current regulation for bias/reference use |
| Surge Current (ISM) | 1000 mA (½-sine, 1/120 s) - supports transient overvoltage clamping without failure |
| Reverse Leakage (IR) | 5 μA max at VR = 47.1 V - guarantees minimal quiescent current in standby protection circuits |
| Operating Temp Range | -65°C to +150°C - enables deployment in automotive engine compartments and industrial controls |
Pinout & Package
DO-41 (DO-204AL) axial-leaded plastic package with cathode indicated by colored band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reverse-biased terminal during regulation | Connected to lower-potential node; carries full Zener current when cathode is biased above Vz |
| Cathode | Zener regulation terminal | Banded end; must be held ≥62 V above anode to enter breakdown and regulate |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the Zener voltage tolerance for 1N4759PE3/TR8?
The 1N4759PE3/TR8 has a nominal Zener voltage of 62 V with a ±5% tolerance, as confirmed by the "A" suffix in its JEDEC designation and verified in the Electrical Characteristics table. This tolerance applies at 4.0 mA test current and 25°C lead temperature, and is maintained across the full operating temperature range of -65°C to +150°C per Microsemi's published data.
Does 1N4759PE3/TR8 require dry packing before reflow?
No, the 1N4759PE3/TR8 is moisture sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without dry pack or baking. This eliminates moisture-related popcorning risk during standard reflow or wave soldering processes, simplifying manufacturing logistics.
What is the maximum surge current rating for 1N4759PE3/TR8?
The 1N4759PE3/TR8 is rated for a maximum surge current (ISM) of 1000 mA, measured using a ½-sine wave pulse of 1/120 second duration at 25°C ambient. This rating enables reliable clamping of short-duration overvoltage events in power rail protection circuits without permanent parameter shift.
How does the thermal resistance of 1N4759PE3/TR8 compare between lead and ambient mounting?
The 1N4759PE3/TR8 has a junction-to-lead thermal resistance of 45°C/W at 3/8" (10 mm) lead length, while junction-to-ambient resistance is 105°C/W on FR4 board with specified copper pad geometry. This difference highlights the importance of lead heat sinking in high-power applications to avoid exceeding the 105°C lead temperature limit.
Is 1N4759PE3/TR8 compatible with lead-free soldering processes?
Yes, the 1N4759PE3/TR8 features RoHS-compliant annealed matte-tin plating qualified for soldering at 260°C for up to 10 seconds, fully supporting lead-free reflow profiles. Its void-free epoxy case meets UL94V-0 flammability requirements, ensuring process compatibility and safety compliance.
