Product details
Overview
1N4760CE3/TR13 from Microsemi is a 68 V, ±2% tolerance, 1 W silicon Zener diode in DO-41 plastic package, rated for 3.7 mA test current, 13 Ω dynamic impedance at IZT, and 51.7 V minimum knee voltage. It regulates voltage in power supply reference and overvoltage protection circuits across -65°C to +150°C.
For engineers reviewing the 1N4760CE3/TR13 datasheet, 1N4760CE3/TR13 pinout, 1N4760CE3/TR13 application, or 1N4760CE3/TR13 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 (TR13).
Technical Context
This device operates in reverse-bias breakdown mode to maintain stable DC voltage under varying load and line conditions. Its sharp knee characteristic (ZZK = 13 Ω at IZK = 0.25 mA) ensures precise regulation onset, while low dynamic impedance (150 Ω at IZT = 3.7 mA) minimizes output variation with current changes.
Designed for axial-lead mounting on FR4 PCBs, it delivers 1.0 W steady-state dissipation at TL < 105°C (3/8" lead length) or TA < 45°C (with specified copper pad layout), and withstands 260°C soldering for 10 s per MIL-STD-750.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 68 V ±2% - precise reference voltage for feedback loops and clamping thresholds |
| Power Dissipation | 1.0 W at TL < 105°C - defines maximum continuous thermal load without derating |
| Test Current (IZT) | 3.7 mA - operating point where VZ and ZZT are guaranteed |
| Dynamic Impedance (ZZT) | 150 Ω at IZT - determines AC ripple rejection capability in regulated supplies |
| Knee Impedance (ZZK) | 13 Ω at IZK = 0.25 mA - ensures stable regulation onset at low currents |
| Surge Current (ISM) | 2000 mA (½-sine, 1/120 s) - supports transient overvoltage absorption in protection circuits |
| Thermal Resistance | 45°C/W junction-to-lead - enables thermal design with discrete lead heatsinking |
Pinout & Package
DO-41 (DO-204AL) plastic axial-lead package with cathode band marking; terminals are anode and cathode; no internal circuitry beyond PN junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener breakdown terminal | Must be biased positive relative to anode to enter regulation; connects to regulated node |
| Anode | Reference/return terminal | Typically grounded or connected to lower-potential rail; completes bias path |
Key Features
| Feature | Design Value |
|---|---|
| ±2% Zener voltage tolerance (C suffix) | Enables tighter feedback loop accuracy than standard ±5% parts, reducing output drift in precision references |
| RoHS-compliant matte-tin plating (e3 suffix) | Ensures solderability and intermetallic compatibility with lead-free assembly processes per JEDEC J-STD-020B |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints, simplifying SMT handling and storage |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Reduces need for ESD mitigation during board assembly and field service |
| Tape-and-reel packaging (TR13 suffix) | Supports automated pick-and-place placement with industry-standard EIA-296 carrier tape |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback converters using optocoupler-coupled feedback. IC Role / Device Role / Timing Role: Zener reference element in secondary-side TL431-like shunt regulator circuit. Use Value: 68 V ±2% VZ sets precise error amplifier threshold, improving output regulation to ±1.5% over line/load/temperature. | Use Scenario: Protecting microcontroller I/O pins from transient surges exceeding 5 V rail. IC Role / Device Role / Timing Role: Shunt clamp diode placed between signal line and ground. Use Value: 2000 mA surge rating absorbs 100 ns–1 µs transients without failure, preventing latch-up in downstream logic. |
| Industrial Sensor Excitation Reference | Programmable Logic Controller Input Conditioning |
Use Scenario: Providing stable excitation voltage for 4–20 mA current-loop pressure sensors. IC Role / Device Role / Timing Role: Precision voltage reference for constant-current source biasing. Use Value: Low ZZK (13 Ω) ensures regulation stability down to 0.25 mA, enabling accurate low-current sensor biasing. | Use Scenario: Level-shifting and overvoltage limiting for 24 V DC digital inputs in PLC backplanes. IC Role / Device Role / Timing Role: Front-end protection diode on input channel before optocoupler isolation. Use Value: 150 Ω ZZT limits voltage excursion during 24 V transients to ≤72 V, staying within optocoupler CTR degradation limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4760A | Same 68 V nominal, but ±5% tolerance (no C suffix); non-RoHS tin-lead plating | Acceptable where cost sensitivity outweighs precision or lead-free compliance | Select only if legacy Pb-based assembly is used and ±5% VZ meets system spec |
| BZX85C68 | 68 V ±5%, 1.3 W rating, DO-41, RoHS-compliant; higher power but looser tolerance | Preferred in high-derating-margin designs where 1.3 W headroom improves long-term reliability | Choose when thermal margin >0.3 W is required and ±5% tolerance is acceptable |
Compared with 1N4760A and BZX85C68, the 1N4760CE3/TR13 offers superior voltage precision (±2% vs. ±5%) and guaranteed RoHS compliance, making it optimal for modern industrial control and automotive-qualified power management where reference accuracy and environmental compliance are jointly critical.

FAQ
What is the Zener voltage tolerance of the 1N4760CE3/TR13?
The 1N4760CE3/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in the part number. This means its measured breakdown voltage at 3.7 mA test current falls between 66.64 V and 69.36 V at 25°C lead temperature. This tighter tolerance supports precision voltage reference applications where standard ±5% devices would introduce unacceptable output variation.
Is the 1N4760CE3/TR13 RoHS compliant?
Yes, the 1N4760CE3/TR13 is RoHS compliant, confirmed by the "e3" suffix denoting matte-tin plating per JEDEC standards. Its terminals meet RoHS Directive 2011/65/EU requirements, and the void-free epoxy body complies with UL94V-0 flammability rating. This makes the 1N4760CE3/TR13 suitable for lead-free reflow assembly and global market deployment.
What is the maximum surge current rating for the 1N4760CE3/TR13?
The 1N4760CE3/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 applies to transient overvoltage events such as ESD or inductive switching spikes. The 1N4760CE3/TR13 maintains regulation integrity under these conditions without parametric shift or failure.
What package type does the 1N4760CE3/TR13 use?
The 1N4760CE3/TR13 uses the DO-41 (JEDEC DO-204AL) axial-lead plastic package. It features a void-free thermosetting epoxy body, tin-plated leads, and cathode polarity marked by a visible band. The package supports manual or automated insertion and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity classification.
How does the thermal resistance of the 1N4760CE3/TR13 affect PCB layout?
With a junction-to-lead thermal resistance of 45°C/W, the 1N4760CE3/TR13 requires at least 3/8 inch (10 mm) of lead length from the body for full 1.0 W dissipation at TL < 105°C. On FR4 boards, achieving 105°C/W junction-to-ambient requires 4 mm² copper pads and 1 mm wide × 25 mm long traces. Proper layout prevents thermal runaway and ensures long-term reliability of the 1N4760CE3/TR13 in continuous operation.
