Product details
Overview
1PMT5952CE3/TR13 from Microsemi is a 130 V, ±5% tolerance Zener diode in the 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-TAB1. It serves as a precision voltage reference or overvoltage clamp in industrial power supplies and automotive ECUs.
For engineers reviewing the 1PMT5952CE3/TR13 datasheet, 1PMT5952CE3/TR13 pinout, 1PMT5952CE3/TR13 application, or 1PMT5952CE3/TR13 equivalent, key selection criteria include its 130 V nominal Zener voltage, 3.0 W power handling in a DO-216 outline, low reverse leakage (≤1 µA at 100 V), ESD rating >16 kV HBM, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage under varying load and temperature conditions. Its Powermite® package features a full metallic bottom for flux-free soldering and an integral locking tab that functions as both mechanical anchor and heat sink, enabling efficient thermal transfer from junction to PCB via TAB 1.
The device exhibits tight regulation with 450 Ω dynamic impedance at IZT = 2.9 mA and maintains ≤1 µA reverse leakage at VR = 100 V. Its junction-to-TAB1 thermal resistance of 30°C/W supports reliable operation up to 150°C storage temperature, with cathode polarity unambiguously marked by TAB 1.

FAQ
What is the Zener voltage tolerance for 1PMT5952CE3/TR13?
The 1PMT5952CE3/TR13 has a standard Zener voltage tolerance of ±5% at 130 V nominal, measured at IZT = 2.9 mA with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the CE3 designation confirms the ±5% version. This tolerance directly impacts accuracy in voltage reference and clamping applications.
How is thermal management handled in the 1PMT5952CE3/TR13 package?
The 1PMT5952CE3/TR13 uses its metallic TAB 1 as the primary thermal conduction path, with a specified junction-to-TAB1 thermal resistance of 30°C/W. To achieve rated 3.0 W dissipation, TAB 1 must be soldered to a minimum 100 mm² copper pour or dedicated heatsink pad. The full metallic bottom prevents flux entrapment and ensures consistent thermal interface quality after reflow.
Is the 1PMT5952CE3/TR13 compatible with lead-free reflow processes?
Yes, the 1PMT5952CE3/TR13 is qualified for standard lead-free reflow profiles, including peak temperatures up to 260°C. Its Powermite® package construction and metallization support JEDEC J-STD-020 compliance. The device's 150°C maximum storage temperature and robust internal wirebonding ensure reliability through multiple reflow cycles without parameter shift or mechanical failure.
What does the 'TR13' suffix indicate in 1PMT5952CE3/TR13?
The 'TR13' suffix denotes tape-and-reel packaging per EIA-481 standard on a 13-inch reel containing 12,000 units. This format is optimized for high-volume SMT placement equipment. The 'CE3' portion specifies ±5% Zener voltage tolerance and 3.0 W power rating, distinguishing it from other variants in the 1PMT59xxB family such as those with tighter tolerances or different power grades.
Can the 1PMT5952CE3/TR13 be used in series or parallel configurations?
The 1PMT5952CE3/TR13 is not recommended for parallel operation due to mismatched Zener impedances causing current imbalance and thermal runaway. For series use, ensure matched units (same lot) and derate total power by 20% per added device to account for VZ tolerance stacking. Always verify thermal coupling and voltage sharing with actual layout testing before deployment.
