Product details
Overview
1PMT5928B/TR7 from Microsemi is a 13 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 7.0 Ω dynamic impedance at 28.8 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in power supply regulation and protection circuits.
For engineers reviewing the 1PMT5928B/TR7 datasheet, 1PMT5928B/TR7 pinout, 1PMT5928B/TR7 application, or 1PMT5928B/TR7 equivalent, key selection criteria include its 13 V nominal Zener voltage, 3.0 W power handling in a compact DO-216 outline, low reverse leakage (≤1 µA at 9.9 V), ESD rating >16 kV HBM, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range. Its Powermite® package features a full metallic bottom and integral heat-sink locking tab, enabling efficient thermal conduction to the PCB pad while eliminating solder flux entrapment during reflow.
The device exhibits low dynamic impedance (7.0 Ω) and knee impedance (400 Ω at 0.25 mA), ensuring stable regulation under varying load conditions. Reverse leakage remains ≤1 µA up to 9.9 V, supporting low-power biasing and precision reference applications where leakage-induced error must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.0 V ±5% at IZT = 28.8 mA - defines regulated output voltage under nominal bias |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous power before thermal derating applies |
| Dynamic Impedance (ZZT) | 7.0 Ω at IZT = 28.8 mA - indicates voltage stability against small current variations |
| Knee Impedance (ZZK) | 400 Ω at IZK = 0.25 mA - characterizes regulation onset near minimum operating current |
| Reverse Leakage (IR) | ≤1 µA at VR = 9.9 V - ensures minimal parasitic current in standby or high-impedance nodes |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt dissipated into PCB copper |
| ESD Rating | >16 kV per Human Body Model - supports robust handling in non-ESD-controlled environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | 12 V nominal, 1 W rating, DO-41 through-hole package, 22 Ω ZZT | Lower power, no integrated heat sink, requires lead-forming and wave soldering | Select when board space permits through-hole mounting and 1 W suffices |
| BZX84-C13 | 13 V nominal, 300 mW rating, SOT-23 package, 30 Ω ZZT | Lower power density, no metallic thermal tab, limited to <0.3 W continuous | Select only for signal-level clamping where 3.0 W capability is unnecessary |
Compared with 1N4742A and BZX84-C13, the 1PMT5928B/TR7 uniquely delivers 13 V regulation at 3.0 W in a surface-mount package with integrated thermal management-enabling higher-reliability power rail protection and reference functions where thermal performance and automated assembly are critical.

FAQ
What is the Zener voltage tolerance for 1PMT5928B/TR7?
The 1PMT5928B/TR7 has a standard Zener voltage tolerance of ±5% at 13.0 V, measured at 28.8 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the /TR7 variant uses the standard ±5% specification.
Can 1PMT5928B/TR7 be used in place of a through-hole Zener like 1N4742A?
While both regulate near 13 V, the 1PMT5928B/TR7 is not a drop-in replacement for 1N4742A due to its surface-mount Powermite® package, 3.0 W rating, and thermal design requiring PCB copper attachment to TAB 1. Direct substitution would require layout revision and thermal validation.
What is the maximum reverse voltage that can be applied to 1PMT5928B/TR7 without breakdown?
The 1PMT5928B/TR7 maintains ≤1 µA reverse leakage up to 9.9 V. Beyond this, current increases sharply toward the 13 V Zener knee. For reliable non-breakdown operation, applied reverse voltage should remain below 9.9 V unless intentional clamping is intended.
How does the Powermite® package improve thermal performance of 1PMT5928B/TR7?
The Powermite® package incorporates a full metallic bottom and integral locking tab that directly bonds to the PCB thermal pad. This achieves a junction-to-TAB1 thermal resistance of 30°C/W, allowing the 1PMT5928B/TR7 to safely dissipate its full 3.0 W rating without external heatsinks when properly mounted.
Is tape-and-reel packaging available for 1PMT5928B/TR7?
Yes, the 1PMT5928B/TR7 is supplied in EIA Standard 481 tape-and-reel format: 3,000 pieces per 7-inch reel or 12,000 pieces per 13-inch reel-optimized for high-volume SMT placement equipment.
