Product details
Overview
1PMT5932E3/TR7 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 1PMT5932E3/TR7 datasheet, 1PMT5932E3/TR7 pinout, 1PMT5932E3/TR7 application, or 1PMT5932E3/TR7 equivalent, key selection considerations include Zener voltage tolerance, power derating above 60°C, reverse leakage at 15.2 V, knee current behavior at 0.25 mA, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This device operates as a two-terminal voltage reference diode with sharp reverse breakdown at 20 V nominal, designed for stable regulation under varying load and temperature conditions. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and eliminate solder flux entrapment during reflow.
The 1PMT5932E3/TR7 exhibits low reverse leakage (≤1 µA at VR = 15.2 V), tight dynamic impedance (14 Ω at IZT = 18.7 mA), and ESD robustness (>16 kV HBM), making it suitable for industrial and automotive subsystems where transient immunity and long-term stability are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 20 V ±5% at IZT = 18.7 mA, TL = 30°C - defines primary regulation setpoint with predictable deviation across temperature |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling before thermal shutdown or degradation |
| Dynamic Impedance (ZZT) | 14 Ω at IZT = 18.7 mA - determines output voltage variation under load current changes |
| Knee Current (IZK) | 0.25 mA - minimum current needed to achieve stable regulation onset near breakdown |
| Reverse Leakage (IR) | ≤1 µA at VR = 15.2 V - ensures minimal standby power loss in high-impedance bias networks |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables thermal design using TAB1 as primary heat path to PCB copper |
| ESD Rating | >16 kV per Human Body Model - supports handling and operation in unshielded industrial environments |

FAQ
What is the Zener voltage tolerance for 1PMT5932E3/TR7?
The 1PMT5932E3/TR7 has a standard Zener voltage tolerance of ±5% at 20 V nominal, measured at IZT = 18.7 mA and TAB 1 temperature of 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available as custom order options, but the E3/TR7 variant ships with the standard ±5% specification.
How is thermal management handled in the 1PMT5932E3/TR7 package?
The 1PMT5932E3/TR7 uses the Powermite® package with TAB 1 as the cathode and primary thermal path. Its 30°C/W junction-to-TAB1 thermal resistance requires direct soldering of TAB 1 to a ≥100 mm² copper thermal pad on the PCB to achieve the full 3.0 W power rating at 60°C case temperature.
Can 1PMT5932E3/TR7 be used in automotive applications?
Yes, the 1PMT5932E3/TR7 is qualified for automotive use with operating junction temperature range of -55°C to +150°C, >16 kV HBM ESD rating, and robust construction that withstands thermal cycling and vibration. It is commonly deployed for reset-line clamping and sensor biasing in body control modules and ADAS power domains.
What is the maximum reverse leakage current for 1PMT5932E3/TR7?
The maximum reverse leakage current for 1PMT5932E3/TR7 is 1 µA at VR = 15.2 V and TL = 30°C. This low leakage supports high-impedance bias networks and minimizes quiescent power loss in battery-powered or energy-sensitive systems.
Is 1PMT5932E3/TR7 compatible with standard SMT reflow profiles?
Yes, the 1PMT5932E3/TR7 is compatible with standard lead-free reflow profiles (J-STD-020). Its molded Powermite® package withstands peak temperatures up to 260°C for 30 seconds, and its EIA-481 tape-and-reel format (7″ reel, 3,000 pcs) supports high-speed pick-and-place equipment without mechanical damage.
