Product details
Overview
1PMT5952B/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 5000 µA max reverse leakage at 98.8 V. It serves as a precision voltage reference or overvoltage clamp in industrial power supplies and DC-DC converter feedback networks.
For engineers reviewing the 1PMT5952B/TR13 datasheet, 1PMT5952B/TR13 pinout, 1PMT5952B/TR13 application, or 1PMT5952B/TR13 equivalent, key selection criteria include zener voltage accuracy (±5%), thermal resistance (30°C/W junction-to-TAB), ESD robustness (>16 kV HBM), low knee impedance (0.25 Ω), and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This device operates as a two-terminal voltage-regulating diode with a defined breakdown threshold at 130 V under 2.9 mA test current. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and mechanical stability during reflow.
The 1PMT5952B/TR13 exhibits 5000 µA maximum reverse leakage at 98.8 V, a 0.25 Ω knee impedance at IZK = 1 mA, and maintains stable regulation across -55°C to +150°C junction temperature range, supporting high-reliability embedded power management where thermal cycling and flux entrapment must be avoided.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 130 V ±5% at IZT = 2.9 mA - defines precise clamping level for overvoltage protection circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables compact high-power regulation without external heatsink |
| Dynamic Impedance (ZZT) | 450 Ω at IZT = 2.9 mA - determines voltage deviation under load transients |
| Knee Impedance (ZZK) | 0.25 Ω at IZK = 1 mA - ensures stable regulation onset near breakdown threshold |
| Reverse Leakage (IR) | 5000 µA max at VR = 98.8 V - sets minimum hold-off voltage before conduction begins |
| Thermal Resistance | 30°C/W junction-to-TAB - quantifies thermal path efficiency for PCB copper pad design |
| ESD Rating | >16 kV per Human Body Model - supports handling and assembly without gate oxide damage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ130A | TVS diode, 130 V standoff, 200 W peak pulse power, unidirectional, DO-214AB package | Designed for transient suppression (IEC 61000-4-5), not precision regulation | Select when surge immunity > precision voltage reference is required |
| BZX84-C130 | 350 mW SOT-23 Zener, 130 V ±5%, 150 Ω ZZT at 5 mA, no metallic thermal tab | Limited power handling and thermal performance; unsuitable for sustained 3 W dissipation | Select only for low-power bias/reference where board space is critical and thermal load is <100 mW |

FAQ
What is the zener voltage tolerance for 1PMT5952B/TR13?
The 1PMT5952B/TR13 has a standard zener voltage tolerance of ±5% at 130 V nominal, measured at 2.9 mA test current and TAB 1 temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the TR13 variant uses the standard ±5% grade.
How is thermal management handled in the 1PMT5952B/TR13 package?
The 1PMT5952B/TR13 uses the Powermite® package with a full metallic bottom and integral locking tab that serves as the primary thermal path. Its specified thermal resistance is 30°C/W junction-to-TAB, requiring direct soldering of TAB 1 to a large copper pour for effective heat dissipation during 3.0 W operation.
Can 1PMT5952B/TR13 be used in automated SMT assembly?
Yes, the 1PMT5952B/TR13 is supplied in EIA-481 standard tape-and-reel format (7-inch reel: 3,000 units), and its Powermite® package geometry is compatible with standard pick-and-place equipment. The locking tab and full metallic bottom also improve placement stability and reduce tombstoning risk.
What is the maximum reverse leakage current for 1PMT5952B/TR13?
The 1PMT5952B/TR13 has a maximum reverse leakage current of 5000 µA at a reverse voltage of 98.8 V, measured at TL = 30°C. This value reflects the device's behavior just below its 130 V breakdown threshold and is critical for low-power bias network design.
Is 1PMT5952B/TR13 suitable for automotive under-hood applications?
Yes, the 1PMT5952B/TR13 supports junction temperatures from -55°C to +150°C and features >16 kV HBM ESD rating, making it suitable for under-hood automotive applications such as engine control unit protection - provided TAB 1 is thermally anchored to chassis ground and power dissipation remains within 3.0 W limits.
