Product details
Overview
1PMT5950CE3/TR7 from Microsemi is a 110 V, ±5% tolerance Zener diode in the Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 300 Ω dynamic impedance at 3.4 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in industrial power supplies and DC-DC converter feedback networks.
For engineers reviewing the 1PMT5950CE3/TR7 datasheet, 1PMT5950CE3/TR7 pinout, 1PMT5950CE3/TR7 application, or 1PMT5950CE3/TR7 equivalent, key selection criteria include Zener voltage tolerance (±5%), low reverse leakage (<1 µA at 83.6 V), ESD robustness (>16 kV HBM), thermal performance under sustained power dissipation, and compatibility with automated SMT assembly using EIA-481 tape-and-reel packaging.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation across varying load currents. Its Powermite® package integrates a full metallic bottom and locking tab that functions as both mechanical anchor and thermal path to PCB copper, enabling efficient heat transfer from junction to TAB 1.
The device exhibits tight voltage control with 110 V nominal Zener voltage measured at 3.4 mA (IZT), 300 Ω dynamic impedance (ZZT), and 1 µA maximum reverse leakage at 83.6 V (VR). Junction-to-TAB1 thermal resistance is specified at 30°C/W, supporting reliable operation up to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 110 V ±5% at IZT = 3.4 mA - defines regulated output voltage in shunt regulator or clamp circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling with PCB thermal management |
| Dynamic Impedance | 300 Ω at IZT - determines voltage deviation under load current changes in regulation applications |
| Reverse Leakage | <1 µA at VR = 83.6 V - ensures minimal quiescent current in standby or high-impedance sensing paths |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt, critical for thermal design on FR4 or metal-core PCBs |
| ESD Rating | >16 kV HBM - supports robustness against handling and system-level electrostatic discharge events |
| Junction Temp Range | –55°C to +150°C - enables deployment in extended-temperature industrial and automotive under-hood environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5950B | Same 110 V Zener voltage, but in DO-41 through-hole package; no metallic thermal tab; 1.2 W power rating | Limited to lower-power, non-SMT designs; unsuitable for automated assembly or high-thermal-load PCBs | Select only when legacy through-hole layout or manual assembly is required |
| SMBJ110A | TVS diode with 110 V standoff voltage; 600 W peak pulse power; higher clamping voltage (152 V) and slower response than Zener | Designed for surge suppression, not precision regulation; cannot replace 1PMT5950CE3/TR7 in feedback or reference roles | Use only for transient protection where regulation accuracy is not required |
Compared with 1N5950B and SMBJ110A, the 1PMT5950CE3/TR7 uniquely combines SMT manufacturability, 3.0 W continuous dissipation via thermal tab, and ±5% voltage tolerance-making it suitable for compact, thermally constrained, precision-regulation applications where alternatives fall short in either power handling, accuracy, or assembly compatibility.

The 1PMT5950CE3/TR7 has a nominal Zener voltage of 110 V with a standard tolerance of ±5%, as confirmed in the MSC0995 datasheet. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, but the CE3 variant specifies ±5%. This tolerance applies at IZT = 3.4 mA and TAB 1 temperature of 30°C.
How is thermal management handled in the 1PMT5950CE3/TR7 package?
The 1PMT5950CE3/TR7 uses the Powermite® package with a full metallic bottom and integral locking tab (TAB 1) that serves as both cathode and primary thermal path. Its junction-to-TAB1 thermal resistance is 30°C/W, enabling 3.0 W dissipation when TAB 1 is thermally anchored to a sufficient copper area on the PCB-no external heatsink required.
Is 1PMT5950CE3/TR7 compatible with automated SMT assembly?
Yes, the 1PMT5950CE3/TR7 is supplied in EIA-481 standard tape-and-reel format (3,000 units per 7-inch reel), designed specifically for compatibility with high-speed pick-and-place equipment. Its Powermite® package geometry and locking tab ensure stable positioning and reliable placement without tombstoning or misalignment.
What is the maximum reverse leakage current for 1PMT5950CE3/TR7?
The maximum reverse leakage current for 1PMT5950CE3/TR7 is 1 µA at a reverse voltage of 83.6 V (VR), as specified in the MSC0995 datasheet's Electrical Characteristics table. This low leakage supports energy-efficient operation in battery-backed or low-quiescent-current systems where standby power loss must be minimized.
Does 1PMT5950CE3/TR7 meet any ESD or reliability certifications?
Yes, the 1PMT5950CE3/TR7 is rated for >16 kV per Human Body Model (HBM) ESD, verified per JEDEC JS-001.
