Product details
Overview
1N4759CE3/TR13 from Microsemi is a 1.0 W, 62 V, ±2% tolerance silicon Zener diode in DO-41 plastic package, designed for precision voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation across industrial and embedded systems.
For engineers reviewing the 1N4759CE3/TR13 datasheet, 1N4759CE3/TR13 pinout, 1N4759CE3/TR13 application, or 1N4759CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy (±2%), dynamic impedance (125 Ω @ 4.0 mA), surge current rating (2000 mA), thermal resistance (45 °C/W junction-to-lead), and RoHS-compliant matte-tin plating.
Technical Context
This device operates in reverse breakdown to maintain stable 62 V regulation across a wide current range (IZK = 0.25 mA to IZM = 70 mA at TA = 50 °C). Its sharp knee characteristic (ZZK = 14 Ω @ 0.25 mA) ensures low-voltage drift under light-load conditions.
Designed for axial-lead mounting on FR4 PCBs with 1 oz copper, it delivers 1.0 W steady-state dissipation at TL < 105 °C (3/8″ lead length) or TA < 45 °C, with thermal resistance of 105 °C/W junction-to-ambient under standard layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V ±2% at IZT = 4.0 mA - enables precise reference generation in feedback networks requiring tight voltage stability |
| Power Dissipation | 1.0 W at TL < 105 °C - supports continuous operation in compact power supplies without forced cooling |
| Dynamic Impedance | 125 Ω @ IZT = 4.0 mA - limits output voltage variation under load transients in regulation circuits |
| Max Reverse Current | 5 μA @ VR = 47.1 V - ensures minimal leakage in high-impedance bias/reference paths |
| Surge Current (ISM) | 2000 mA (½-sine, 1/120 s) - withstands transient overvoltage events in protection clamping applications |
| Forward Voltage | 1.2 V max @ 200 mA - defines conduction behavior during forward-biased fault conditions |
| Operating Temp | –65 °C to +150 °C - suitable for under-hood automotive, industrial control, and aerospace environments |
Pinout & Package
DO-41 (DO-204AL) plastic axial-leaded package with cathode indicated by colored band; terminals are tin-lead or RoHS-compliant matte-tin plated per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reverse-bias reference node | Connected to lower-potential side of regulated circuit; carries full Zener current during regulation |
| Cathode (banded end) | Zener voltage reference output | Provides stable 62 V reference point relative to anode; must be held positive w.r.t. anode for breakdown operation |
Key Features
| Feature | Design Value |
|---|---|
| ±2% Zener voltage tolerance (C suffix) | Reduces calibration overhead in precision reference designs versus standard ±5% (A) or ±10% (no suffix) variants |
| RoHS-compliant "e3" suffix | Meets EU Directive 2011/65/EU with annealed matte-tin plating, eliminating lead-based solder compatibility concerns |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life restrictions, simplifying SMT and manual assembly logistics |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Enables handling without special static-control protocols in production and field repair environments |
| Low thermal resistance (45 °C/W) | Improves power derating margin vs. glass-body alternatives, supporting higher ambient temperatures in enclosed enclosures |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or forward converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Provides stable 62 V reference to TL431-like shunt regulator ICs or discrete error amplifiers. Use Value: ±2% tolerance minimizes output voltage deviation across line/load/temperature, reducing need for post-production trimming. | Use Scenario: Protecting downstream logic or analog circuitry from input surges exceeding 62 V. IC Role / Device Role / Timing Role: Acts as crowbar element that conducts heavily above 62 V to divert excess energy to ground. Use Value: 2000 mA surge rating allows absorption of repetitive transients without degradation, extending system reliability. |
| Programmable Reference Voltage Source | Industrial Sensor Excitation |
Use Scenario: Generating fixed bias voltages for ADC references, DAC outputs, or op-amp level-shifting networks. IC Role / Device Role / Timing Role: Serves as primary voltage reference in unregulated DC rails where ultra-low noise is not required. Use Value: 125 Ω dynamic impedance ensures <10 mV shift under 1 mA load variation, supporting 12-bit accuracy. | Use Scenario: Supplying stable excitation voltage to resistive temperature detectors (RTDs) or strain gauges in PLC analog input modules. IC Role / Device Role / Timing Role: Delivers low-drift, low-noise 62 V bias to bridge sensors operating in harsh factory environments. Use Value: –65 °C to +150 °C operating range maintains regulation integrity near motors, drives, and hydraulic systems. |
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) and non-RoHS tin-lead plating | Acceptable where tighter tolerance not required and legacy Pb-based assembly remains in use | Select when cost sensitivity outweighs precision or RoHS compliance requirements |
| BZX85C62 | 62 V ±5%, 1.3 W rating, DO-41 package, but higher ZZT (200 Ω) and no documented MIL-PRF-19500 screening option | Suitable for commercial-grade consumer power supplies, not recommended for military or extended-temp industrial use | Choose for higher power margin in benign environments; avoid where low impedance or extended temp range is critical |
Compared with 1N4759A and BZX85C62, the 1N4759CE3/TR13 offers superior voltage accuracy (±2% vs. ±5%), guaranteed RoHS compliance, and verified performance across –65 °C to +150 °C - making it optimal for high-reliability industrial and aerospace voltage reference designs where long-term stability and regulatory compliance are mandatory.

FAQ
What is the Zener voltage tolerance of the 1N4759CE3/TR13?
The 1N4759CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in the part number. This means its measured breakdown voltage at 4.0 mA test current falls within 60.76 V to 63.24 V at 25 °C. This tighter tolerance reduces calibration effort in precision reference applications compared to the ±5% 1N4759A variant.
Does the 1N4759CE3/TR13 meet RoHS requirements?
Yes, the 1N4759CE3/TR13 meets RoHS Directive 2011/65/EU requirements. The "e3" suffix confirms RoHS-compliant matte-tin terminal plating, and the device is manufactured using lead-free processes per Microsemi's qualification standards. It is suitable for use in environmentally regulated commercial and industrial products.
What is the maximum surge current rating for the 1N4759CE3/TR13?
The 1N4759CE3/TR13 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 reliable clamping of short-duration overvoltage transients in protection circuits without permanent degradation of the Zener characteristic.
Can the 1N4759CE3/TR13 be used in high-temperature environments?
Yes, the 1N4759CE3/TR13 is rated for continuous operation from –65 °C to +150 °C. Its thermal resistance of 45 °C/W (junction-to-lead) and 105 °C/W (junction-to-ambient on FR4) supports reliable regulation in enclosed industrial enclosures or near heat-generating components, provided power dissipation remains within derated limits per Figure 1 of the datasheet.
What does the "TR13" suffix indicate in 1N4759CE3/TR13?
The "TR13" suffix indicates tape-and-reel packaging per EIA-296 standard, with 13-inch reels. This format supports automated pick-and-place assembly and ensures consistent orientation (cathode band facing same direction) for high-volume manufacturing. The base part 1N4759CE3 remains electrically and thermally identical regardless of packaging format.
