Product details
Overview
1PMT5951CE3/TR13 from Microsemi is a 120 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 380 Ω dynamic impedance at 3.1 mA test current and 4500 µA max reverse leakage at 91.2 V, used for precision voltage regulation in industrial power supplies and overvoltage protection circuits.
For engineers reviewing the 1PMT5951CE3/TR13 datasheet, 1PMT5951CE3/TR13 pinout, 1PMT5951CE3/TR13 application, or 1PMT5951CE3/TR13 equivalent, key selection considerations include zener voltage tolerance (±5%), thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates as a two-terminal voltage reference device with cathode designated by TAB 1, requiring no external biasing circuitry. Its full metallic bottom and integral heat sink locking tab enable reliable thermal conduction and flux-free reflow soldering.
The device is characterized at TL = 30°C with zener voltage measured 20 seconds after applying DC test current; dynamic impedance is derived using 60 Hz RMS AC current equal to 10% of IZT, per Micro Note 202 for voltage-current deviation analysis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 120 V ±5% at IZT = 3.1 mA - defines stable regulation point under nominal bias |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous thermal load in PCB-mounted condition |
| Dynamic Impedance (ZZT) | 380 Ω at IZT = 3.1 mA - indicates regulation stiffness against small-signal current variation |
| Knee Impedance (ZZK) | 0.25 Ω at IZK = 1 mA - reflects low-voltage regulation capability near breakdown threshold |
| Reverse Leakage (IR) | 4500 µA max at VR = 91.2 V - quantifies off-state conduction loss in clamping applications |
| Thermal Resistance | 30°C/W junction-to-TAB1 - determines temperature rise per watt dissipated into mounting pad |
| ESD Rating | >16 kV per Human Body Model - ensures robustness during handling and board assembly |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375B | Same 120 V nominal zener voltage but DO-204AL package; 3.0 W rating at 50°C ambient, higher thermal resistance (50°C/W) | Requires larger PCB footprint and less efficient thermal coupling than Powermite® | Prefer 1PMT5951CE3/TR13 where space-constrained SMT and superior thermal performance are required |
| BZX85C120 | 120 V ±5% zener in DO-41 package; 1.3 W power rating, 1000 Ω ZZT, no ESD rating specified | Limited to lower-power regulation and lacks ESD robustness for automated assembly environments | Select 1PMT5951CE3/TR13 for 3.0 W operation, 380 Ω regulation stiffness, and >16 kV HBM compliance |

FAQ
What is the zener voltage tolerance for 1PMT5951CE3/TR13?
The 1PMT5951CE3/TR13 has a standard zener voltage tolerance of ±5% at 120 V nominal, measured at IZT = 3.1 mA with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with C and D suffixes respectively, but the CE3 designation confirms the ±5% version. This tolerance directly impacts regulation accuracy in feedback and protection circuits.
How is thermal management handled in the 1PMT5951CE3/TR13 package?
The 1PMT5951CE3/TR13 uses the Powermite® package with a full metallic bottom and integral heat sink locking tab that conducts heat directly from the junction to the PCB copper pour via TAB 1. Its specified thermal resistance is 30°C/W junction-to-TAB1, enabling 3.0 W dissipation at TAB 1 = 60°C-critical for sustained operation in enclosed or high-ambient environments.
Is the 1PMT5951CE3/TR13 compatible with automated SMT assembly processes?
Yes, the 1PMT5951CE3/TR13 is fully compatible with automated insertion and reflow soldering equipment. Its Powermite® package features a unique locking tab for mechanical stability and a full metallic bottom that prevents solder flux entrapment-key requirements for high-yield, repeatable SMT manufacturing per EIA-481 tape-and-reel standards.
What is the maximum reverse leakage current for 1PMT5951CE3/TR13?
The 1PMT5951CE3/TR13 specifies a maximum reverse leakage current (IR) of 4500 µA at VR = 91.2 V, measured at TL = 30°C. This value reflects off-state conduction under clamping conditions and is critical for minimizing standby power loss in voltage reference and protection circuits.
Does the 1PMT5951CE3/TR13 have ESD protection built-in?
Yes, the 1PMT5951CE3/TR13 is rated for >16 kV per the Human Body Model (HBM), as confirmed in the MSC0995 datasheet. This ESD robustness is intrinsic to the device structure and packaging, eliminating the need for external protection components during handling, assembly, or operation in electrically noisy environments.
