Product details
Overview
1N4759APE3/TR12 from Microsemi is a 1.0 W, 62 V ±5% axial-lead silicon Zener diode in DO-41 (DO-204AL) plastic package, rated for 4.0 mA test current, 125 Ω dynamic impedance at IZT, and 70 μA reverse leakage at 47.1 V, used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N4759APE3/TR12 datasheet, 1N4759APE3/TR12 pinout, 1N4759APE3/TR12 application, or 1N4759APE3/TR12 equivalent, key selection criteria include Zener voltage tolerance, 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 breakdown to maintain stable 62 V output across 1.0–2000 mA operating current range, with temperature coefficient near +0.085 %/°C (derived from typical 12 mV/°C at 62 V). 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.
Regulation performance is validated at 25 °C lead temperature with 90-second DC stabilization; knee impedance is specified at 0.25 mA (ZZK = 14 Ω), supporting low-current biasing in analog references while sustaining full 1.0 W dissipation up to 105 °C lead temperature or 45 °C ambient on FR4 board.
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 suitable for feedback divider accuracy |
| Power Dissipation | 1.0 W at TL ≤ 105 °C - supports continuous operation in compact power supplies with 3/8″ lead length |
| Dynamic Impedance (ZZT) | 125 Ω at IZT = 4.0 mA - determines AC ripple rejection capability in regulated outputs |
| Reverse Leakage Current | 70 μA max at VR = 47.1 V - ensures minimal quiescent error in high-impedance reference nodes |
| Surge Current (ISM) | 2000 mA peak - withstands transient overloads during startup or fault conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor 1N4759A | Same 62 V ±5%, 1.0 W, DO-41; non-RoHS tin-lead plating; no "e3" or "TR" suffixes | Requires separate tape-and-reel ordering; not pre-qualified for lead-free reflow | Select when legacy SnPb assembly is used and RoHS compliance is not required |
| Vishay 1N4759A-E3/54 | Identical electrical specs; same "e3" RoHS suffix but "54" denotes bulk packaging instead of tape-and-reel | Not supplied in EIA-296 conformant reel; requires manual loading or different feeder setup | Select when volume hand-soldering or prototype builds outweigh automated placement needs |
Compared with ON Semiconductor 1N4759A and Vishay 1N4759A-E3/54, the 1N4759APE3/TR12 uniquely combines RoHS compliance, tape-and-reel packaging per EIA-296, and Microsemi's extended temperature qualification - making it optimal for high-reliability automated production requiring traceable sourcing and lifecycle continuity.

FAQ
What is the Zener voltage tolerance of the 1N4759APE3/TR12?
The 1N4759APE3/TR12 has a Zener voltage tolerance of ±5%, as indicated by the "A" suffix in its JEDEC part number. This means its nominal 62 V breakdown voltage is guaranteed between 58.9 V and 65.1 V at 4.0 mA test current and 25 °C lead temperature, supporting stable regulation in precision feedback networks.
Does the 1N4759APE3/TR12 require dry packing before PCB assembly?
No, the 1N4759APE3/TR12 is moisture classified as Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored and assembled without dry pack or baking. Its plastic DO-41 encapsulation and void-free epoxy body eliminate moisture absorption concerns, simplifying SMT and through-hole manufacturing flow.
What is the maximum surge current rating for the 1N4759APE3/TR12?
The 1N4759APE3/TR12 is rated for 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 reliable transient suppression in 48 V DC bus protection and power supply inrush limiting applications.
Is the 1N4759APE3/TR12 compatible with lead-free reflow soldering?
Yes, the 1N4759APE3/TR12 features RoHS-compliant annealed matte-tin plating ("e3" suffix) qualified for lead-free reflow profiles up to 260 °C for 10 seconds. Its termination meets MIL-STD-750 Method 2026 solderability requirements, ensuring robust wetting and joint integrity in both SnPb and Pb-free processes.
How does the thermal resistance of the 1N4759APE3/TR12 compare to glass-body Zeners?
The 1N4759APE3/TR12 exhibits 45 °C/W junction-to-lead thermal resistance - significantly lower than equivalent glass-body (G-suffix) Zeners due to its plastic molded construction and optimized thermal path. This improves power handling at elevated temperatures and reduces derating requirements in compact power designs.
