Product details
Overview
1N4759CP/TR12 from Microsemi is a 1.0 W axial-lead silicon Zener diode with nominal Zener voltage of 62 V, ±5% tolerance (A suffix), plastic DO-41 package, and RoHS-compliant matte-tin plating. It regulates voltage in power supply reference and overvoltage protection circuits across -65°C to +150°C, delivering stable 62 V regulation at 4.0 mA test current with 125 Ω dynamic impedance.
For engineers reviewing the 1N4759CP/TR12 datasheet, 1N4759CP/TR12 pinout, 1N4759CP/TR12 application, or 1N4759CP/TR12 equivalent, key selection criteria include its 62 V Zener voltage, 1.0 W power rating at 25°C, DO-41 mechanical form factor, 125 Ω Zener impedance at 4.0 mA, and TR12 tape-and-reel packaging for automated assembly.
Technical Context
This Zener operates in reverse breakdown to maintain a stable 62 V reference across a wide current range (0.25 mA to 70 mA), with thermal resistance of 45°C/W junction-to-lead (3/8" lead length) and 105°C/W junction-to-ambient on FR4 board. Its 125 Ω dynamic impedance at 4.0 mA ensures low output variation under load transients.
The device features a cathode band marking, tin-lead or RoHS-compliant matte-tin terminations, UL94V-0 epoxy body, and moisture sensitivity level 1-no dry pack required. It supports surge currents up to 2000 mA (½-sine, 1/120 s) and exhibits <5 μA reverse leakage at 47.1 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V ±5% at 4.0 mA - defines precise regulation point for feedback loops and voltage clamping |
| Power Dissipation | 1.0 W at TL < 105°C - sets maximum continuous thermal load on leads without derating |
| Dynamic Impedance (ZZT) | 125 Ω at IZT = 4.0 mA - determines output voltage deviation under varying load current |
| Reverse Leakage Current | <5 μA at VR = 47.1 V - ensures minimal standby power loss in high-impedance bias networks |
| Surge Current (ISM) | 2000 mA (½-sine, 1/120 s) - enables transient overvoltage suppression without failure |
| Operating Temperature | -65°C to +150°C - supports deployment in automotive engine compartments and industrial controls |
| Package | DO-41 (DO-204AL) - standard axial-leaded through-hole footprint compatible with legacy PCB tooling |

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 "P" suffix → glass-body DO-35 package; higher thermal resistance (junction-to-lead: 55°C/W vs. 45°C/W) | Less suitable for high-power-density layouts requiring efficient heat conduction through leads | Select 1N4759CP/TR12 when lead-mounted thermal performance or RoHS compliance is required |
| MMSZ4708T1G | Surface-mount SOD-123 package; 62 V, 500 mW rating; 100 Ω ZZT @ 2.5 mA | Lower power handling and different mounting method-requires PCB redesign and thermal pad optimization | Choose MMSZ4708T1G only for space-constrained SMT designs where 1.0 W dissipation is not needed |

FAQ
What is the Zener voltage tolerance for 1N4759CP/TR12?
The 1N4759CP/TR12 has a nominal Zener voltage of 62 V with ±5% tolerance, indicated by the "A" suffix in the part number per JEDEC registration. This tolerance applies at 25°C lead temperature with 4.0 mA test current and ensures predictable regulation in feedback and clamping circuits without requiring post-manufacturing calibration.
Does 1N4759CP/TR12 require dry packing before reflow soldering?
No, the 1N4759CP/TR12 is moisture sensitivity level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored and processed without dry pack or baking. Its plastic DO-41 package and void-free epoxy body eliminate moisture absorption risk, simplifying manufacturing flow and reducing yield loss from popcorning.
What is the maximum steady-state power dissipation for 1N4759CP/TR12?
The 1N4759CP/TR12 is rated for 1.0 W steady-state power dissipation at lead temperature (TL) below 105°C with 3/8" (10 mm) lead length from body, or at ambient temperature (TA) below 45°C when mounted on FR4 board with specified copper area. Derating is required above these temperatures per Figure 1 in the official datasheet.
How is polarity marked on 1N4759CP/TR12?
The 1N4759CP/TR12 uses a single black cathode band on the plastic DO-41 body to indicate polarity. During Zener operation, the banded end must be held at higher potential relative to the non-banded (anode) end. This marking is laser-etched or molded and remains visible after soldering, supporting correct orientation in manual and automated assembly.
Is 1N4759CP/TR12 RoHS compliant?
Yes, the "e3" suffix in 1N4759CP/TR12 confirms RoHS compliance per EU Directive 2011/65/EU. The device uses annealed matte-tin plating on leads and halogen-free UL94V-0 epoxy encapsulation-fully documented in Microsemi's official compliance statements and certified by authorized third-party testing labs.
