Product details
Overview
1PMT5934C/TR13 from Microsemi is a 24 V ±1% Zener diode in Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 19 Ω dynamic impedance at 15.6 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as precision voltage reference and overvoltage clamp in power supply regulation circuits.
For engineers reviewing the 1PMT5934C/TR13 datasheet, 1PMT5934C/TR13 pinout, 1PMT5934C/TR13 application, or 1PMT5934C/TR13 equivalent, key selection criteria include its ±1% Zener tolerance (C-suffix), 16.7 V reverse breakdown voltage at IZK = 1 mA, 700 µA max reverse leakage at VR = 18.2 V, ESD rating >16 kV HBM, and DO-216 mechanical outline compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across load variations and temperature shifts. Its Powermite® package integrates a full metallic bottom and locking tab that functions as both mechanical anchor and thermal path to PCB copper, enabling efficient heat transfer without solder flux entrapment.
The device exhibits tight knee characteristics: 1 mA knee current (IZK) at 16.7 V with 700 Ω knee impedance (ZZK), supporting low-current regulation stability. Electrical specs are validated at TL = 30°C with 20-second DC stabilization per Micro Note 202 for voltage-current deviation analysis.

FAQ
What is the Zener voltage tolerance for 1PMT5934C/TR13?
The "C" suffix in 1PMT5934C/TR13 denotes ±1% Zener voltage tolerance at 24.0 V nominal, verified at IZT = 15.6 mA and TAB 1 temperature of 30°C. This tighter tolerance enables use in precision reference circuits where standard ±5% devices would require calibration or trimming. The 1PMT5934C/TR13 achieves this without sacrificing power rating or thermal performance.
How does the Powermite® package improve thermal performance of 1PMT5934C/TR13?
The Powermite® package of 1PMT5934C/TR13 uses a full metallic bottom and integral locking tab (TAB 1) to provide direct thermal conduction from the silicon junction to the PCB copper pad. With a measured thermal resistance of 30°C/W junction-to-TAB1, it reduces operating temperature rise by up to 40% compared to plastic-packaged Zeners with equivalent ratings. This allows 1PMT5934C/TR13 to sustain 3.0 W continuously under controlled board layout conditions.
Is 1PMT5934C/TR13 compatible with automated SMT assembly processes?
Yes, 1PMT5934C/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 DO-216 outline and locking tab ensure stable placement and alignment during pick-and-place. The full metallic bottom prevents solder flux entrapment, eliminating post-reflow cleaning steps and enhancing long-term solder joint integrity in high-volume manufacturing.
What is the maximum reverse leakage current for 1PMT5934C/TR13 at 18.2 V?
At VR = 18.2 V and TL = 30°C, the maximum reverse leakage current for 1PMT5934C/TR13 is 700 µA. This value is specified in the manufacturer's electrical characteristics table and reflects worst-case leakage under standardized test conditions. Low IR ensures minimal quiescent power loss in high-impedance bias networks, making 1PMT5934C/TR13 suitable for battery-powered and energy-sensitive applications.
Does 1PMT5934C/TR13 meet automotive qualification standards?
While 1PMT5934C/TR13 is not AEC-Q200 certified as a standalone component, its construction-junction temperature range of –55°C to +150°C, >16 kV HBM ESD rating, and robust Powermite® package-supports use in automotive body control modules and power distribution units. Designers must validate system-level compliance per ISO 7637-2 and ISO 16750-2; the 1PMT5934C/TR13 has been deployed in Tier-1 automotive applications where discrete Zener clamping is required.
