Product details
Overview
1N4760E3/TR13 from Microsemi is a 1.0 W, 68 V ±5% Zener diode in DO-41 plastic package, rated for 3.7 mA test current (IZT), 150 Ω dynamic impedance (ZZT), and 2000 mA maximum regulator current (IZM) at TA = 50°C. It operates from –65°C to +150°C and regulates voltage in power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N4760E3/TR13 datasheet, 1N4760E3/TR13 pinout, 1N4760E3/TR13 application, or 1N4760E3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (45°C/W junction-to-lead), surge current rating (2000 mA), RoHS compliance (e3 suffix), and axial-leaded DO-41 mechanical compatibility.
Technical Context
This discrete Zener diode functions as a two-terminal voltage reference device operating in reverse breakdown. Its regulation performance is defined at 3.7 mA test current with 150 Ω dynamic impedance and exhibits a temperature coefficient of approximately +3.5 mV/°C near 68 V, per Microsemi's published curve (Figure 3).
The device uses silicon PN-junction construction with void-free thermosetting epoxy encapsulation (UL94V-0), tin-lead or matte-tin plating, and cathode band polarity marking. It meets MIL-STD-750 ESD immunity (Method 1020) and IPC/JEDEC J-STD-020B moisture sensitivity Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 68 V ±5% at IZT = 3.7 mA - defines nominal regulation point with tight tolerance suitable for precision reference designs |
| Power Dissipation | 1.0 W at TL < 105°C (3/8″ lead length) - sets maximum continuous DC power handling under specified thermal conditions |
| Dynamic Impedance | 150 Ω at IZT = 3.7 mA - indicates voltage stability under small-signal AC variations around operating point |
| Max Regulator Current | 2000 mA at TA = 50°C - determines peak steady-state reverse current before thermal runaway |
| Thermal Resistance | 45 °C/W junction-to-lead - enables thermal design using lead conduction path; 105 °C/W junction-to-ambient on FR4 |
| Reverse Leakage | 5 μA max at VR = 51.7 V - ensures low standby power loss below regulation threshold |
| Surge Current | 2000 mA (½-sine, 1/120 s) - supports transient overvoltage clamping without failure |
Pinout & Package
DO-41 (JEDEC DO-204AL) axial-leaded plastic package with cathode indicated by color band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node; reverse bias applied across anode–cathode for regulation |
| Cathode | Zener breakdown terminal / regulation output node | Banded end; connected to unregulated input; maintains stable 68 V relative to anode during reverse conduction |
Key Features
| Feature | Design Value |
|---|---|

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 ±5%, DO-41, but non-RoHS tin-lead plating; no "e3" suffix | Not suitable for RoHS-compliant production; otherwise identical electrical behavior | Select 1N4760A only for legacy or exempt applications requiring Sn/Pb finish |
| MMBZ5255B | Surface-mount SOT-23, 68 V ±5%, 225 mW - lower power, different package and thermal profile | Used in space-constrained PCBs where axial DO-41 is impractical; requires re-layout | Choose MMBZ5255B when board area is critical and power demand stays below 225 mW |
Compared with 1N4760A and MMBZ5255B, the 1N4760E3/TR13 offers full 1.0 W dissipation in through-hole DO-41 with RoHS compliance and proven surge robustness-making it optimal for industrial power rails where reliability and regulatory alignment are mandatory.

FAQ
What is the Zener voltage tolerance of the 1N4760E3/TR13?
The 1N4760E3/TR13 has a Zener voltage tolerance of ±5%, confirmed by the "A" suffix in its JEDEC designation (1N4760A base) and documented in Microsemi's REV C datasheet. This means its actual breakdown voltage falls between 64.6 V and 71.4 V at 3.7 mA test current and 25°C lead temperature. The tolerance remains valid across the full operating temperature range of –65°C to +150°C.
Does the 1N4760E3/TR13 meet RoHS requirements?
Yes, the 1N4760E3/TR13 is RoHS compliant, as indicated by the "e3" suffix per Microsemi's documentation. It features annealed matte-tin plating and void-free UL94V-0 epoxy encapsulation, satisfying EU Directive 2011/65/EU. No lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE substances exceed allowable thresholds.
What is the maximum surge current rating for the 1N4760E3/TR13?
The 1N4760E3/TR13 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 applies to transient overvoltage events such as ESD or inductive kickback, and is validated per Microsemi's test methodology in Note 3 of the datasheet.
Can the 1N4760E3/TR13 be used in surface-mount designs?
No, the 1N4760E3/TR13 uses a DO-41 axial-leaded package and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMAJ4760A and MLL4760A in DO-214AC and SOD-123 packages respectively - both share the same 68 V ±5% specification but differ in thermal and mechanical characteristics.
What is the thermal resistance of the 1N4760E3/TR13, and how does it affect PCB layout?
The 1N4760E3/TR13 has a junction-to-lead thermal resistance of 45°C/W at 3/8″ (10 mm) lead length from the body. When mounted on FR4 with 1 oz Cu, 4 mm² pads, and 1 mm × 25 mm trace, junction-to-ambient resistance rises to 105°C/W. Layout must ensure adequate copper area and minimal trace length to avoid exceeding 105°C junction temperature at 1.0 W dissipation.
