Product details
Overview
1PMT5952AE3/TR13 from Microsemi is a 130 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 450 Ω dynamic impedance at 2.9 mA test current and thermal resistance of 30°C/W junction-to-TAB1 - used for precision voltage regulation and overvoltage protection in high-reliability DC power rails.
For engineers reviewing the 1PMT5952AE3/TR13 datasheet, 1PMT5952AE3/TR13 pinout, 1PMT5952AE3/TR13 application, or 1PMT5952AE3/TR13 equivalent, key selection criteria include zener voltage accuracy, power derating at elevated case temperatures, low reverse leakage (<1 µA at 100 V), ESD robustness (>16 kV HBM), and compatibility with automated SMT assembly using EIA-481 tape-and-reel packaging.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp or regulate voltage across load circuits. Its Powermite® package integrates a full metallic bottom and locking tab that serves as both mechanical anchor and thermal path to PCB copper, enabling efficient heat transfer without solder flux entrapment.
The 1PMT5952AE3/TR13 is characterized at TL = 30°C with IZT = 2.9 mA; its knee current (IZK) is 0.25 mA and knee impedance (ZZK) is 5000 Ω, indicating stable regulation onset above threshold. Reverse leakage remains ≤1 µA up to VR = 100 V, supporting low-power standby circuit integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 130 V ±5% at IZT = 2.9 mA - defines nominal regulation point with tight production control for stable reference accuracy. |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous DC power handling before thermal shutdown; derates linearly above 60°C case temperature. |
| Dynamic Impedance (ZZT) | 450 Ω at IZT = 2.9 mA - quantifies AC voltage variation per mA change; lower values improve regulation stability under load transients. |
| Thermal Resistance | 30°C/W junction-to-TAB1 - determines temperature rise per watt; requires adequate PCB copper area under TAB 1 for thermal management. |
| Reverse Leakage (IR) | ≤1 µA at VR = 100 V - ensures minimal quiescent current draw in high-impedance bias networks or battery-backed circuits. |
| ESD Rating | >16 kV per Human Body Model - provides robust handling margin during board assembly and field operation without external protection. |
Pinout & Package
Package: Powermite® surface-mount molded package with full metallic bottom and integral locking tab; cathode designated by TAB 1; mounting position unrestricted; weight ≈ 0.016 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and electrical cathode connection; must be soldered to PCB copper pour for thermal and electrical performance. |
| Lead 2 | Anode | Standard anode terminal; connects to ground or lower-potential node in reverse-biased regulation configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling comparable to larger through-hole Zeners. |
| Integral heat sink locking tab | Provides mechanical retention during reflow and direct thermal conduction path from junction to PCB, reducing thermal resistance to 30°C/W. |
| Full metallic bottom | Eliminates solder flux entrapment risk during assembly, improving long-term reliability and solder joint integrity. |
| ESD robustness >16 kV HBM | Reduces need for external ESD protection components in sensitive input or interface circuits. |
Applications
| Industrial Power Supply Regulation | Telecom Line Card Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5952B | Same 130 V, ±5%, but in DO-41 through-hole package; no metallic heat sink tab; 60°C/W thermal resistance. | Limited to lower-power or non-automated assembly; unsuitable for high-density SMT layouts or thermal-critical designs. | Select 1N5952B only when legacy through-hole compatibility or manual repair is required. |
| BZX85C130 | 130 V, ±5%, DO-41; 1.3 W rating; higher ZZT (~1000 Ω); no specified ESD rating. | Lower power handling and thermal performance; not recommended for sustained 3 W operation or ESD-prone environments. | Choose BZX85C130 only for cost-sensitive, low-duty-cycle applications where 130 V reference suffices. |
Compared with 1N5952B and BZX85C130, the 1PMT5952AE3/TR13 delivers superior thermal management (30°C/W vs. ≥60°C/W), automated assembly readiness, and certified ESD immunity - making it the preferred choice for high-reliability SMT power regulation.

The 1PMT5952AE3/TR13 has a standard zener voltage tolerance of ±5% at 130 V, measured at IZT = 2.9 mA and TAB 1 temperature of 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the base part number 1PMT5952AE3/TR13 specifies ±5%.
How is thermal performance managed in the 1PMT5952AE3/TR13 package?
The 1PMT5952AE3/TR13 uses the Powermite® package with a full metallic bottom and integral locking tab that functions as both mechanical anchor and primary thermal path. Its junction-to-TAB1 thermal resistance is 30°C/W, requiring direct soldering of TAB 1 to a PCB copper pour for effective heat dissipation at full 3.0 W rating.
Is the 1PMT5952AE3/TR13 compatible with standard SMT assembly processes?
Yes, the 1PMT5952AE3/TR13 is designed for compatibility with automated insertion and reflow soldering. It ships in EIA-481 tape-and-reel format (7-inch reel: 3,000 pieces; 13-inch reel: 12,000 pieces) and features a flux-free metallic bottom to prevent entrapment during reflow.
What is the maximum reverse leakage current for 1PMT5952AE3/TR13?
The 1PMT5952AE3/TR13 exhibits a maximum reverse leakage current (IR) of 1 µA at VR = 100 V, measured at TL = 30°C. This low leakage supports use in high-impedance bias networks and battery-powered monitoring circuits where standby current must be minimized.
Does the 1PMT5952AE3/TR13 meet any ESD standards?
Yes, the 1PMT5952AE3/TR13 is rated for >16 kV electrostatic discharge per the Human Body Model (HBM), as confirmed in the official Microsemi MSC0995 datasheet. This eliminates the need for additional on-board ESD protection in many interface and sensor applications.
