Product details
Overview
1N4759PE3/TR12 from Microsemi is a 1.0 W axial-lead silicon Zener diode with nominal zener voltage 62 V, ±5% tolerance (A-suffix), 4.0 mA test current (IZT), 125 Ω dynamic impedance at IZT, and 5 μA maximum reverse leakage at 47.1 V. It regulates voltage in power supply reference and overvoltage protection circuits operating from −65 °C to +150 °C.
For engineers reviewing the 1N4759PE3/TR12 datasheet, 1N4759PE3/TR12 pinout, 1N4759PE3/TR12 application, or 1N4759PE3/TR12 equivalent, key selection criteria include its DO-41 package thermal resistance (45 °C/W junction-to-lead), 2000 mA surge current rating, RoHS-compliant matte-tin plating, and JEDEC-registered 5% tolerance specification.
Technical Context
This Zener operates in reverse breakdown to maintain stable voltage across load variations and temperature shifts. Its 62 V nominal regulation point targets mid-range DC rail stabilization, with 125 Ω dynamic impedance ensuring low AC ripple transmission under 4.0 mA test bias.
The device uses a plastic DO-41 (DO-204AL) package with cathode band marking, tin-lead or RoHS-compliant matte-tin terminals, and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. Thermal derating begins at 105 °C lead temperature or 45 °C ambient on FR4 board.

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 terminations only; same electrical specs and DO-41 package | Not compliant with lead-free assembly mandates; requires Pb-based solder process | Select when legacy Pb-process compatibility is required and RoHS exemption applies |

FAQ
What is the zener voltage tolerance of the 1N4759PE3/TR12?
The 1N4759PE3/TR12 has a ±5% zener voltage tolerance, confirmed by its "A" suffix per JEDEC standard. This means its measured VZ falls between 58.9 V and 65.1 V when tested at 4.0 mA and 25 °C lead temperature. The tolerance is guaranteed across the full −65 °C to +150 °C operating range, making the 1N4759PE3/TR12 suitable for applications demanding consistent regulation accuracy under thermal stress.
Does the 1N4759PE3/TR12 require dry packing before PCB assembly?
No, the 1N4759PE3/TR12 does not require dry packing. It is moisture sensitivity level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored and assembled without baking or humidity-controlled handling. This simplifies logistics and eliminates pre-reflow bake cycles-a key advantage for high-volume manufacturing of the 1N4759PE3/TR12 in industrial and automotive applications.
What is the maximum surge current rating for the 1N4759PE3/TR12?
The 1N4759PE3/TR12 supports a maximum surge current (ISM) of 2000 mA, measured using a ½-sine wave pulse of 1/120 second duration at 25 °C ambient. This rating enables the 1N4759PE3/TR12 to absorb short-duration transients-such as load dump spikes in automotive systems-without degradation, provided average power remains within its 1.0 W derated limit.
How does the "e3" suffix affect soldering compatibility for the 1N4759PE3/TR12?
The "e3" suffix on the 1N4759PE3/TR12 indicates RoHS-compliant matte-tin plating, qualified for lead-free reflow soldering at 260 °C for up to 10 seconds. This allows the 1N4759PE3/TR12 to be processed alongside other RoHS-compliant components without contamination risk, while maintaining compatibility with both SnPb and Pb-free assembly lines-critical for global electronics manufacturing of the 1N4759PE3/TR12.
What is the thermal resistance junction-to-lead for the 1N4759PE3/TR12?
The 1N4759PE3/TR12 has a thermal resistance of 45 °C/W junction-to-lead when measured at 3/8″ (10 mm) lead length from the body. This value enables precise thermal modeling in power supply designs, allowing engineers to calculate junction temperature rise directly from lead temperature measurements-ensuring safe operation of the 1N4759PE3/TR12 even in thermally constrained enclosures.
