Product details
Overview
1PMT5932CE3/TR13 from Microsemi is a 20 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 14 Ω dynamic impedance at 18.7 mA test current and thermal resistance of 30°C/W junction-to-TAB1 - used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the 1PMT5932CE3/TR13 datasheet, 1PMT5932CE3/TR13 pinout, 1PMT5932CE3/TR13 application, or 1PMT5932CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance (±5%), low reverse leakage (≤1 µA at 15.2 V), ESD robustness (>16 kV HBM), thermal performance (30°C/W), and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This Zener diode operates as a two-terminal voltage reference and clamp device, with cathode designated by TAB 1 and full metallic bottom enabling reliable thermal conduction and flux-free soldering. Its DO-216 mechanical outline supports high-density PCB layouts while maintaining 3.0 W power handling in a miniature surface-mount form factor.
The device exhibits tight knee characteristics (IZK = 0.25 mA, ZZK = 650 Ω) and low dynamic impedance (14 Ω at IZT = 18.7 mA), ensuring stable regulation across load and temperature variations. It is specified for junction temperatures from –55°C to +150°C and features >16 kV human-body-model ESD immunity.
Key Specifications

FAQ
What is the Zener voltage tolerance for 1PMT5932CE3/TR13?
The 1PMT5932CE3/TR13 has a nominal Zener voltage of 20 V with a standard tolerance of ±5%, as confirmed in the MSC0995 datasheet. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, but the CE3 variant specifies ±5%. This tolerance applies at IZT = 18.7 mA and TAB temperature of 30°C, and is critical for designs requiring predictable regulation margins.
How is thermal performance defined for 1PMT5932CE3/TR13?
The 1PMT5932CE3/TR13 has a thermal resistance of 30°C/W junction-to-TAB1, meaning each watt dissipated raises the junction temperature 30°C above the TAB temperature. This value assumes proper soldering of TAB 1 to a minimum 10 mm² copper pad with ≥2 thermal vias. Derating is required above 60°C TAB temperature to maintain 3.0 W maximum power dissipation.
Is 1PMT5932CE3/TR13 compatible with automated SMT assembly?
Yes, the 1PMT5932CE3/TR13 is fully compatible with automated insertion and reflow processes. It ships in EIA-481 compliant tape-and-reel format (13-inch reel, 12,000 units), and its Powermite® package features a unique locking tab and full metallic bottom that prevent flux entrapment and improve placement stability - verified in Microsemi's application notes for high-yield SMT lines.
What is the reverse leakage specification for 1PMT5932CE3/TR13?
The reverse leakage current (IR) for 1PMT5932CE3/TR13 is guaranteed ≤1 µA at VR = 15.2 V and TL = 30°C, per the MSC0995 datasheet. This low leakage supports energy-efficient designs such as battery-powered sensors and always-on monitoring circuits where quiescent current must remain below 1 µA to extend operational lifetime.
Does 1PMT5932CE3/TR13 have ESD protection built-in?
Yes, the 1PMT5932CE3/TR13 features an ESD rating exceeding 16 kV per the Human Body Model (HBM), as stated in the MSC0995 datasheet. This intrinsic robustness eliminates the need for external ESD protection in many applications and ensures reliability during handling, automated assembly, and end-use in electrically noisy environments like industrial controls and automotive ECUs.
