Product details
Overview
1PMT5930B/TR7 from Microsemi is a 3.0 W surface-mount Zener diode in the Powermite® package, rated for 16 V nominal Zener voltage at 23.4 mA test current, with 10 Ω dynamic impedance and 12.2 mA maximum Zener current. It serves as a precision voltage reference or overvoltage clamp in power supply regulation and transient protection circuits.
For engineers reviewing the 1PMT5930B/TR7 datasheet, 1PMT5930B/TR7 pinout, 1PMT5930B/TR7 application, or 1PMT5930B/TR7 equivalent, key selection criteria include its ±5% Zener tolerance, 30°C/W junction-to-tab thermal resistance, ESD rating >16 kV HBM, and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
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, directly coupling thermal energy from the junction to PCB copper.
The device exhibits low reverse leakage (≤1 µA at 1 V), tight knee characteristics (IZK = 0.25 mA), and controlled dynamic impedance (10 Ω at IZT), enabling reliable regulation in low-current reference paths and fast-response clamping applications where thermal stability and ESD robustness are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V at 23.4 mA - defines stable regulation point for feedback loops or clamping thresholds |
| Power Dissipation | 3.0 W at TAB1 = 60°C - sets maximum continuous DC power handling with heatsinked mounting |
| Dynamic Impedance (ZZT) | 10 Ω at 23.4 mA - determines voltage deviation under load transients (ΔV = ΔI × 10 Ω) |
| Junction-to-Tab Thermal Resistance | 30°C/W - quantifies thermal path efficiency from die to PCB copper via metal tab |
| ESD Rating (HBM) | >16 kV - ensures robustness against human-body model discharge during handling and assembly |
| Reverse Leakage (IR) | ≤1 µA at VR = 1 V - minimizes quiescent current in high-impedance bias/reference networks |
| Zener Current (IZM) | 12.2 mA - maximum DC current before exceeding 3.0 W dissipation at rated thermal condition |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | 14 V nominal Zener voltage, 1 W power rating, DO-41 through-hole package | Lower power handling and thermal performance; requires manual or wave soldering | Choose only if lower voltage and through-hole assembly are acceptable |
| BZX84-C16 | 16 V nominal Zener, 300 mW rating, SOT-23 package, 30 Ω dynamic impedance | Insufficient power and thermal capability for sustained 3.0 W clamping or regulation | Select when space-constrained PCBs demand SOT-23 but power requirements are ≤300 mW |
Compared with 1N4744A and BZX84-C16, the 1PMT5930B/TR7 delivers triple the power rating of the latter and double the thermal conductivity of the former-enabling reliable 3.0 W operation in automated SMT environments where voltage stability, ESD immunity, and thermal management are jointly critical.

FAQ
What is the Zener voltage tolerance for the 1PMT5930B/TR7?
The 1PMT5930B/TR7 has a standard Zener voltage tolerance of ±5% at 16 V nominal, measured at 23.4 mA test current and TAB1 temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the base 1PMT5930B/TR7 uses the ±5% grade.
How is thermal management handled in the 1PMT5930B/TR7 package?
The 1PMT5930B/TR7 uses the Powermite® package with TAB 1 as the cathode and primary thermal path. Its 30°C/W junction-to-tab thermal resistance requires direct soldering of TAB 1 to a copper pour or thermal pad to dissipate up to 3.0 W reliably. The integral locking tab enhances mechanical and thermal coupling to the PCB.
Is the 1PMT5930B/TR7 compatible with automated SMT assembly processes?
Yes, the 1PMT5930B/TR7 is specifically designed for automated insertion and reflow. It ships in EIA-481 tape-and-reel format (3,000 pieces per 7-inch reel), and its Powermite® package includes a locking tab and full metallic bottom to ensure precise placement and eliminate solder flux entrapment during reflow.
What is the maximum reverse leakage current for the 1PMT5930B/TR7?
The 1PMT5930B/TR7 specifies a maximum reverse leakage current (IR) of 1 µA at 1 V reverse voltage and 30°C. This low leakage supports high-impedance reference and bias applications where quiescent current must remain minimal across temperature and voltage ranges.
Does the 1PMT5930B/TR7 meet any ESD robustness standards?
Yes, the 1PMT5930B/TR7 is rated for >16 kV per the Human Body Model (HBM) ESD test. This level of robustness is built into the device structure and eliminates the need for additional board-level ESD protection in many transient-clamping applications.
