Product details
Overview
1PMT5953E3/TR13 from Microsemi is a 150 V, ±5% tolerance surface-mount Zener diode in the Powermite® package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 600 Ω dynamic impedance at 2.5 mA test current and 16 kV HBM ESD rating - used for precision voltage regulation and overvoltage protection in industrial power supplies.
For engineers reviewing the 1PMT5953E3/TR13 datasheet, 1PMT5953E3/TR13 pinout, 1PMT5953E3/TR13 application, or 1PMT5953E3/TR13 equivalent, key selection criteria include zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB1), reverse leakage (<1 µA at 114 V), compatibility with EIA-481 tape-and-reel automation, and full metallic bottom for flux-free soldering.
Technical Context
This Zener diode operates as a two-terminal voltage reference device with cathode designated by TAB 1, requiring no external bias circuitry. Its Powermite® package integrates a locking tab that functions as an integral heat sink and provides mechanical retention during reflow.
The device exhibits tight voltage regulation under stable thermal conditions: zener voltage is specified at IZT = 2.5 mA with TL = 30°C, and dynamic impedance (ZZT) is measured using 60 Hz RMS AC superimposed at 10% of IZT, confirming low AC impedance behavior near nominal operating point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 150 V ±5% at IZT = 2.5 mA - defines stable clamping threshold for overvoltage protection circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling with defined thermal boundary condition |
| Dynamic Impedance (ZZT) | 600 Ω at IZT = 2.5 mA - indicates voltage regulation sensitivity to current variation near operating point |
| Junction-to-TAB Thermal Resistance | 30°C/W - quantifies thermal path efficiency from die to mounting tab for PCB-level thermal design |
| ESD Rating (HBM) | >16 kV - ensures robustness against human-body-model electrostatic discharge during handling and assembly |
| Reverse Leakage Current | <1 µA at VR = 114 V - guarantees minimal standby power loss in high-impedance bias networks |
| Forward Voltage | 1.2 V at IF = 200 mA - defines conduction drop when used in series rectification or crowbar configurations |
Pinout & Package
Package: Powermite® surface-mount molded package with full metallic bottom and integral heat-sink locking tab; cathode identified by TAB 1; compatible with EIA-481 tape-and-reel (13-inch reel, 12,000 pieces).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-dissipating terminal and voltage reference node; must be connected to ground or low-impedance return path |
| Lead 2 | Anode | Current entry point during reverse-bias regulation; electrically isolated from TAB 1 per DO-216 mechanical outline |
Key Features
| Feature | Design Value |
|---|---|
| Integral heat-sink locking tab | Provides mechanical retention during automated insertion and enhances thermal transfer from junction to PCB copper |
| Full metallic bottom | Eliminates solder flux entrapment risk, improving long-term reliability and solder joint integrity |
| DO-216 mechanical outline | Ensures compatibility with standard SMT pick-and-place tooling and reflow profiles for high-yield manufacturing |
| 16 kV HBM ESD rating | Reduces need for external ESD protection in board-level transient suppression designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375B | Same 150 V nominal voltage but TO-277 package; 3.0 W rating at 75°C ambient, higher thermal resistance (40°C/W) | Requires larger PCB footprint and less efficient thermal coupling than Powermite® | Select when legacy TO-277 layout compatibility is required over thermal performance |
| BZX85C150 | 150 V, ±5%, but only 1.3 W power rating and DO-41 through-hole package | Not suitable for high-power SMT applications; limited surge handling capability | Choose only for low-cost, low-power prototyping where 3 W dissipation is not needed |
Compared with 1N5375B and BZX85C150, the 1PMT5953E3/TR13 delivers superior thermal management via its 30°C/W junction-to-TAB resistance and compact Powermite® footprint, enabling higher power density and better reliability in automated SMT production environments.

FAQ
What is the zener voltage tolerance for 1PMT5953E3/TR13?
The 1PMT5953E3/TR13 has a standard zener voltage tolerance of ±5% at 150 V nominal, measured at IZT = 2.5 mA and TAB temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the E3 suffix denotes the standard ±5% grade. This tolerance directly impacts regulation accuracy in precision reference applications.
How is thermal performance specified for 1PMT5953E3/TR13?
The 1PMT5953E3/TR13 specifies a junction-to-TAB thermal resistance of 30°C/W, meaning each watt dissipated raises the junction temperature 30°C above the TAB 1 temperature. This value assumes direct thermal contact between TAB 1 and a copper plane; actual performance depends on PCB copper area and thickness. It enables reliable 3.0 W operation when TAB 1 is held at ≤60°C.
Is 1PMT5953E3/TR13 compatible with automated SMT assembly?
Yes, the 1PMT5953E3/TR13 is fully compatible with automated SMT assembly. It uses EIA-481 standard tape-and-reel packaging (13-inch reel, 12,000 units), features a DO-216 outline optimized for pick-and-place nozzles, and includes a locking tab that improves mechanical stability during placement and reflow. Its full metallic bottom also prevents flux entrapment during soldering.
What is the maximum reverse leakage current for 1PMT5953E3/TR13?
The maximum reverse leakage current for 1PMT5953E3/TR13 is 1 µA at VR = 114 V (76% of nominal 150 V zener voltage), tested at TL = 30°C. This low leakage supports high-impedance bias networks and minimizes standby power loss in battery-operated or energy-sensitive systems where the 1PMT5953E3/TR13 serves as a reference or clamp element.
Does 1PMT5953E3/TR13 meet any ESD immunity standards?
Yes, the 1PMT5953E3/TR13 is rated for >16 kV per the Human Body Model (HBM) ESD standard, verified per JEDEC JS-001. This high immunity level reduces susceptibility to damage during handling, board assembly, and field operation - particularly valuable in manufacturing environments and end-equipment subject to frequent operator interaction or static-prone conditions where the 1PMT5953E3/TR13 provides protection or regulation.
