Product details
Overview
1PMT5932BE3/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. It serves as a precision voltage reference or overvoltage clamp in compact DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5932BE3/TR7 datasheet, 1PMT5932BE3/TR7 pinout, 1PMT5932BE3/TR7 application, or 1PMT5932BE3/TR7 equivalent, key selection criteria 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-regulating diode with sharp Zener breakdown at 20 V nominal. Its Powermite® package integrates a full metallic bottom and locking tab that functions as both mechanical anchor and thermal path to PCB copper, enabling direct heat conduction from junction to TAB 1.
Electrical performance is specified at TL = 30°C with IZT = 18.7 mA; voltage measurement must occur within 20 seconds of DC current application. Dynamic impedance (14 Ω) and knee impedance (650 Ω at IZK = 0.25 mA) define regulation linearity across operating current range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 20 V ±5% at IZT = 18.7 mA - defines stable regulation point under nominal bias |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power before thermal shutdown |
| Dynamic Impedance ZZT | 14 Ω at IZT - determines output voltage variation per mA change in load current |
| Knee Current IZK | 0.25 mA - minimum current needed to enter usable regulation region |
| Reverse Leakage IR | 1 µA max at VR = 15.2 V - ensures low standby power loss in clamping applications |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt dissipated into PCB pad |
| ESD Rating | >16 kV HBM - supports handling without external protection in low-risk assembly environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF20A (ON Semiconductor) | 20 V, 200 W peak pulse power, 1.0 A Ipp, SOD-123 package, 100 ns response | Designed for transient suppression, not DC regulation; higher leakage (5 µA @ 15.2 V) | Choose for surge-only protection where DC power handling is secondary |
| BZX84-C20 (Nexperia) | 20 V, ±5%, 300 mW, SOT-23, 40 Ω ZZT, 200 mA IZM | Limited to low-power biasing due to 0.3 W rating and higher thermal resistance | Choose only for signal-level references below 5 mA; unsuitable for 3 W clamping |
Compared with SMF20A and BZX84-C20, the 1PMT5932BE3/TR7 uniquely combines 3.0 W DC power capability, 14 Ω regulation impedance, and Powermite® thermal design-making it the only option among the three qualified for sustained 20 V clamping in industrial power supplies.

FAQ
What is the maximum continuous power dissipation for 1PMT5932BE3/TR7?
The 1PMT5932BE3/TR7 is rated for 3.0 W DC power dissipation when TAB 1 is maintained at 60°C. Derating is required above this temperature per the 30°C/W thermal resistance specification; at TAB 1 = 100°C, maximum allowable power drops to approximately 1.8 W. This limit assumes adequate PCB copper area for heat spreading.
How is cathode identification implemented on 1PMT5932BE3/TR7?
The cathode of the 1PMT5932BE3/TR7 is unambiguously designated by TAB 1-the large metallic pad on the package bottom. This is confirmed in the MSC0995.PDF mechanical specifications and must be connected to the lower-potential node in all circuit implementations. Lead 2 serves as the anode.
Does 1PMT5932BE3/TR7 meet industry-standard ESD requirements?
Yes, the 1PMT5932BE3/TR7 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), as stated in the FEATURES section of MSC0995.PDF. This qualifies it for direct handling in standard manufacturing environments without requiring additional ESD protection circuitry during board assembly.
What is the Zener test current and how does it affect regulation accuracy of 1PMT5932BE3/TR7?
The 1PMT5932BE3/TR7 is characterized at IZT = 18.7 mA, where VZ = 20 V ±5%. Operating significantly below this current-especially near the knee region (IZK = 0.25 mA)-increases dynamic impedance and reduces regulation accuracy. For stable reference use, maintain bias ≥10 mA.
Can 1PMT5932BE3/TR7 be used in place of through-hole Zener diodes like 1N5248B?
No-1PMT5932BE3/TR7 is not a drop-in replacement for 1N5248B. While both are 20 V Zeners, the 1PMT5932BE3/TR7 delivers 3.0 W in a surface-mount Powermite® package with thermal path via TAB 1, whereas 1N5248B is a 0.5 W through-hole device in DO-35. PCB layout, thermal design, and power handling differ fundamentally.
