Product details
Overview
1N4760CP/TR8 from Microsemi is a 1.0 W axial-lead silicon Zener diode with a nominal Zener voltage of 68 V, ±5% tolerance (A-suffix), plastic DO-41 package, and rated for operation from −65 °C to +150 °C. It delivers stable voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation where low thermal resistance and JEDEC-standard compliance are required.
For engineers reviewing the 1N4760CP/TR8 datasheet, 1N4760CP/TR8 pinout, 1N4760CP/TR8 application, or 1N4760CP/TR8 equivalent, key selection criteria include Zener voltage accuracy, dynamic impedance at test current, maximum regulator current at 50 °C, surge current capability, and RoHS-compliant tape-and-reel packaging (TR8 suffix).
Technical Context
This Zener operates in reverse breakdown mode with cathode band indicating polarity; regulation occurs when the banded end is held positive relative to the anode. Its 68 V nominal Zener voltage is specified at 3.7 mA test current (IZT), with dynamic impedance of 150 Ω and knee impedance of 13 Ω at 0.25 mA (IZK).
Thermal performance is defined by junction-to-lead resistance of 45 °C/W (3/8″ lead length) and junction-to-ambient resistance of 105 °C/W on FR4 board. Maximum steady-state power remains 1.0 W only if lead temperature stays below 105 °C or ambient stays below 45 °C under specified PCB layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 68 V ±5% at IZT = 3.7 mA - defines precise regulation point for feedback or clamping |
| Power Dissipation | 1.0 W at TL < 105 °C - limits continuous DC power handling without derating |
| Dynamic Impedance (ZZT) | 150 Ω at IZT = 3.7 mA - indicates voltage stability under small-signal AC ripple |
| Max Regulator Current (IZM) | 65 mA at TA = 50 °C - sets upper bound for safe DC bias current in regulation mode |
| Surge Current (ISM) | 2000 mA (½-sine, 1/120 s) - supports transient overvoltage absorption without failure |
| Reverse Leakage (IR) | 5 μA max at VR = 51.7 V - ensures minimal quiescent current in standby clamping |
| Forward Voltage | 1.2 V max at IF = 200 mA - defines conduction loss during forward-biased fault conditions |
Pinout & Package
Package: DO-41 (DO-204AL), axial-lead, plastic molded thermosetting epoxy case (UL94V-0), cathode indicated by colored band. Terminals are tin-lead or RoHS-compliant matte-tin plated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Non-banded end | Connected to lower-potential node; carries reverse leakage and forward conduction current |
| Cathode | Banded end | Connected to higher-potential node; establishes Zener breakdown voltage reference point |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener | Complies with industry-standard 1N47xxA series mechanical and electrical definitions |
| Plastic construction (P suffix) | Lower thermal resistance vs. glass-body variants - improves power handling in compact layouts |
| Tape-and-reel packaging (TR8) | Standard EIA-296 compliant - enables automated SMT placement despite axial form factor |
| Moisture sensitivity Level 1 | No dry pack required - simplifies handling and eliminates bake-out prior to assembly |
| Nonsensitive to ESD | Qualified per MIL-STD-750 Method 1020 - reduces risk of damage during manual handling or board assembly |
Applications
| Switch-Mode Power Supply Feedback | Industrial Overvoltage Clamp |
|---|---|
Use Scenario: Used in TL431-based or discrete op-amp feedback networks to regulate output voltage in 24–72 V DC-DC converters. IC Role / Device Role / Timing Role: Provides stable 68 V reference for error amplifier comparison; absorbs transient excursions above setpoint. Use Value: Maintains ±5% output regulation across line/load/temperature with 150 Ω dynamic impedance limiting ripple coupling. | Use Scenario: Placed across motor drive bus or relay coil to suppress inductive kickback spikes exceeding 60 V. IC Role / Device Role / Timing Role: Acts as passive shunt clamp; conducts only when bus voltage exceeds 68 V ±5%, diverting surge energy to ground. Use Value: Absorbs 2000 mA surge pulses without degradation, protecting downstream MOSFETs and controllers. |
| Programmable Voltage Reference | Field Instrument Signal Conditioning |
Use Scenario: Paired with precision resistor dividers to generate adjustable 5–68 V references for ADC biasing or DAC calibration. IC Role / Device Role / Timing Role: Serves as primary Zener reference element; stabilized by constant-current source at 3.7 mA.

IC Role / Device Role / Timing Role: Functions as fail-safe clamping diode on sensor input rail; blocks >68 V transients while passing normal signal range. Use Value: Withstands repeated 5 μA leakage up to 51.7 V and operates reliably from −65 °C to +150 °C in harsh enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4760A | No TR8 tape-and-reel; bulk or ammo-pack only; same electrical specs and DO-41 package | Not suitable for automated pick-and-place; requires manual or vibratory feed | Select 1N4760CP/TR8 when high-volume SMT assembly is required; choose 1N4760A for prototyping or low-volume hand-soldered builds |
| MMSZ4712T1G | Surface-mount SOD-123 package; 68 V ±5%; 500 mW rating; 300 Ω ZZT; 100 mA IZM | Lower power and smaller footprint; unsuitable for >0.5 W continuous dissipation or high-surge environments | Choose MMSZ4712T1G only for space-constrained, low-power signal-level clamping; retain 1N4760CP/TR8 for 1 W power regulation or 2 A surge duty. |
Compared with 1N4760A and MMSZ4712T1G, the 1N4760CP/TR8 uniquely combines JEDEC-standard DO-41 mechanical compatibility, full 1 W power rating, 2000 mA surge capability, and EIA-296 tape-and-reel packaging - making it the only option supporting high-reliability, high-power, and automated production requirements simultaneously.

FAQ
What is the Zener voltage tolerance of the 1N4760CP/TR8?
The 1N4760CP/TR8 has a nominal Zener voltage of 68 V with a tolerance of ±5%, as indicated by the "A" suffix in its part number. This tolerance is guaranteed at 3.7 mA test current and 25 °C lead temperature. The "P" denotes plastic DO-41 packaging, and "TR8" specifies EIA-296 tape-and-reel packaging for automated assembly. The 1N4760CP/TR8 meets JEDEC registration requirements for the 1N47xxA family.
Does the 1N4760CP/TR8 support RoHS compliance?
Yes, the 1N4760CP/TR8 is RoHS compliant, as confirmed by the "e3" designation in Microsemi's official documentation for the 1N4728AP–1N4764AP,e3 series. The device uses annealed matte-tin plating on terminals and void-free UL94V-0 epoxy encapsulation. RoHS compliance applies to both the component itself and its TR8 tape-and-reel carrier. The 1N4760CP/TR8 satisfies EU Directive 2011/65/EU and related amendments without exemptions.
What is the maximum surge current rating for the 1N4760CP/TR8?
The 1N4760CP/TR8 is rated for a maximum non-repetitive reverse surge current (ISM) of 2000 mA, measured using a ½-sine wave pulse of 1/120 second duration at 25 °C ambient. This rating enables reliable suppression of inductive switching transients and lightning-induced surges in industrial controls. The 1N4760CP/TR8 maintains this capability without parameter shift due to its 1 W power rating and low thermal resistance DO-41 package.
Can the 1N4760CP/TR8 be used in surface-mount designs?
The 1N4760CP/TR8 is an axial-lead DO-41 device and is not a surface-mount component; however, its TR8 tape-and-reel packaging allows use in automated through-hole insertion equipment. For true SMT implementation, Microsemi offers the SMAJ4760A and MLL4760A as surface-mount equivalents. The 1N4760CP/TR8 itself requires hole mounting and wave or selective soldering - its design intent is high-power axial reliability, not planar footprint reduction.
What is the thermal resistance specification for the 1N4760CP/TR8?
The 1N4760CP/TR8 has a junction-to-lead thermal resistance (RθJL) of 45 °C/W when measured at 3/8″ (10 mm) lead length from the body, and a junction-to-ambient resistance (RθJA) of 105 °C/W when mounted on FR4 board with 1 oz copper, 4 mm² pads, and 1 mm × 25 mm traces. These values define safe operating area boundaries: 1.0 W dissipation is only permissible if lead temperature remains below 105 °C or ambient stays under 45 °C. The 1N4760CP/TR8 data sheet provides full derating curves in Figure 1.
