Product details
Overview
1N4759CPE3/TR8 from Microsemi is a 1.0 W, 62 V ±2% tolerance silicon Zener diode in DO-41 plastic package, rated for 4.0 mA test current, 125 Ω dynamic impedance at IZT, and 5 μA reverse leakage at 47.1 V, used for precision voltage regulation in power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N4759CPE3/TR8 datasheet, 1N4759CPE3/TR8 pinout, 1N4759CPE3/TR8 application, or 1N4759CPE3/TR8 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (45 °C/W junction-to-lead), surge current rating (2000 mA), RoHS-compliant matte-tin plating, and tape-and-reel packaging (TR8).
Technical Context
This Zener operates in reverse breakdown to maintain stable 62 V output across 1.0–2000 mA operating current range, with sharp knee characteristics verified by dual-point Zener impedance measurement per MicroNote 202. Its 2% voltage tolerance (C suffix) and low 125 Ω dynamic impedance at 4.0 mA ensure tight regulation under varying load conditions.
Designed for axial-lead mounting on FR4 PCBs with 1 oz copper, it delivers 1.0 W steady-state power at TL < 105 °C (3/8″ lead length) or TA < 45 °C, with thermal resistance of 105 °C/W junction-to-ambient under defined layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V ±2% at 4.0 mA - ensures precise reference voltage with minimal drift in feedback loops |
| Power Dissipation | 1.0 W at 25 °C - defines maximum continuous DC power handling before thermal derating |
| Dynamic Impedance (ZZT) | 125 Ω at 4.0 mA - indicates low AC impedance for stable regulation under small-signal ripple |
| Reverse Leakage Current | 5 μA at 47.1 V - confirms low off-state conduction for reliable clamping below breakdown |
| Surge Current (ISM) | 2000 mA - supports transient overvoltage suppression without failure |
| Thermal Resistance | 45 °C/W junction-to-lead - enables accurate thermal design using standard lead-mounting geometry |
| Forward Voltage | 1.2 V max at 200 mA - defines forward conduction loss when used bidirectionally or in series |
Pinout & Package
DO-41 (DO-204AL) plastic package with axial leads: cathode indicated by color band; banded end must be held positive relative to anode for Zener operation. Void-free UL94V-0 epoxy body, tin-lead or RoHS-compliant matte-tin plating, 0.7 g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common; reverse-biased configuration requires this terminal at lower potential |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4759A | Same 62 V nominal, but ±5% tolerance (A suffix) vs. ±2% (C suffix) | Lower accuracy; suitable where cost priority outweighs regulation stability | Select 1N4759CPE3/TR8 when ±2% tolerance is required for closed-loop feedback or precision sensing |
| MMSZ5259ET1G | Surface-mount SOD-123 package, same 62 V ±5%, 500 mW rating | Not drop-in compatible; requires PCB redesign; limited surge capability (500 mA) | Choose MMSZ5259ET1G only for space-constrained designs accepting reduced power and surge margin |
Compared with 1N4759A and MMSZ5259ET1G, the 1N4759CPE3/TR8 provides tighter voltage control and higher surge robustness in through-hole form factor, making it optimal for industrial power supplies requiring long-term calibration stability and transient immunity.

FAQ
What is the Zener voltage tolerance of the 1N4759CPE3/TR8?
The 1N4759CPE3/TR8 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in the part number. This means its nominal 62 V breakdown voltage is guaranteed between 60.76 V and 63.24 V when measured at 4.0 mA test current and 25 °C lead temperature. This tighter tolerance supports applications demanding higher regulation accuracy than the standard ±5% (A suffix) version.
Does the 1N4759CPE3/TR8 require dry packing before reflow soldering?
No, the 1N4759CPE3/TR8 does not require dry packing. It is moisture sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored and handled indefinitely at ambient conditions without baking. This eliminates pre-reflow moisture removal steps and reduces manufacturing complexity compared to higher-level moisture-sensitive devices.
What is the maximum surge current rating for the 1N4759CPE3/TR8?
The 1N4759CPE3/TR8 has a maximum surge current (ISM) rating of 2000 mA, measured using a ½ sine-wave pulse of 1/120 second duration at 25 °C ambient. This rating enables the device to absorb short-duration overvoltage transients-such as relay coil kickback or ESD-induced spikes-without degradation, supporting robust front-end protection in industrial power circuits.
Is the 1N4759CPE3/TR8 RoHS compliant?
Yes, the 1N4759CPE3/TR8 is RoHS compliant, as confirmed by the "e3" suffix. It features RoHS-compliant annealed matte-tin plating on its axial leads and meets EU Directive 2011/65/EU requirements. The device is solderable per MIL-STD-750 Method 2026 and qualified for reflow up to 260 °C for 10 seconds.
How does the thermal resistance of the 1N4759CPE3/TR8 affect PCB layout?
The 1N4759CPE3/TR8 has a junction-to-lead thermal resistance of 45 °C/W at 3/8″ (10 mm) lead length from body, meaning PCB layout must maintain adequate lead length and copper area to avoid exceeding 105 °C lead temperature at 1.0 W dissipation. For junction-to-ambient operation, use 4 mm² copper pads and 1 mm track width to achieve 105 °C/W and stay within 45 °C ambient limit.
