Product details
Overview
1PMT5952C/TR13 from Microsemi is a 130 V, ±1% tolerance Zener diode in Powermite® surface-mount 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-tab. It serves as precision voltage reference or overvoltage clamp in industrial power supplies and automotive control modules.
For engineers reviewing the 1PMT5952C/TR13 datasheet, 1PMT5952C/TR13 pinout, 1PMT5952C/TR13 application, or 1PMT5952C/TR13 equivalent, key selection criteria include its 130 V nominal Zener voltage, ±1% tolerance (denoted by 'C' suffix), 3.0 W power handling in DO-216 outline, and ESD rating >16 kV HBM - critical for ruggedized embedded systems requiring stable clamping under transient stress.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with tightly controlled voltage regulation across its specified test current range. Its DO-216 mechanical outline features a full metallic bottom and integral heat sink locking tab, enabling direct thermal conduction to PCB copper and eliminating solder flux entrapment during reflow assembly.
The device exhibits low reverse leakage (≤1 µA at VR = 100 V) and a knee current of 0.25 mA, supporting stable regulation even at low bias currents. Its 30°C/W junction-to-tab thermal resistance allows predictable derating when mounted on thermally optimized pads per Microsemi's recommended footprint.

FAQ
What is the Zener voltage tolerance of 1PMT5952C/TR13?
The 'C' suffix in 1PMT5952C/TR13 denotes ±1% Zener voltage tolerance at 2.9 mA test current and TAB 1 temperature of 30°C. This tighter tolerance than standard ±5% versions (e.g., 1PMT5952B) enables higher accuracy in voltage reference and clamping applications without external calibration.
How is thermal management handled in the 1PMT5952C/TR13 package?
The 1PMT5952C/TR13 uses a Powermite® package with a full metallic bottom and integral heat sink locking tab (TAB 1). This design provides a direct thermal path from the silicon junction to the PCB, achieving 30°C/W junction-to-tab thermal resistance - allowing safe 3.0 W dissipation when TAB 1 is maintained at ≤60°C.
What does the 'TR13' suffix indicate in 1PMT5952C/TR13?
The 'TR13' suffix indicates tape-and-reel packaging per EIA-481 standard on a 13-inch reel containing 12,000 units. This format is optimized for automated SMT placement and supports high-volume manufacturing with verified moisture sensitivity level (MSL) compliance per J-STD-020.
Can 1PMT5952C/TR13 be used in automotive applications?
Yes, 1PMT5952C/TR13 is qualified for automotive use with operating junction temperature range of –55°C to +150°C, >16 kV HBM ESD rating, and robust DO-216 mechanical construction. It meets requirements for load-dump protection and reference voltage generation in body control modules and powertrain subsystems.
What is the maximum reverse leakage current for 1PMT5952C/TR13?
The maximum reverse leakage current for 1PMT5952C/TR13 is 1 µA at reverse voltage VR = 100 V and TL = 30°C. This low leakage ensures minimal power loss in always-on monitoring circuits and preserves accuracy in high-impedance voltage divider networks.
