Product details
Overview
1PMT5928AE3/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 - used for precision voltage regulation and overvoltage protection in compact DC-DC converter feedback loops.
For engineers reviewing the 1PMT5928AE3/TR7 datasheet, 1PMT5928AE3/TR7 pinout, 1PMT5928AE3/TR7 application, or 1PMT5928AE3/TR7 equivalent, key selection criteria include zener voltage tolerance, power derating above 60°C, knee current (0.25 mA), reverse leakage (<1 µA at 10.4 V), and ESD robustness (>16 kV HBM).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its Powermite® package integrates a full metallic bottom and locking tab for mechanical stability and thermal conduction to PCB copper, enabling reliable operation up to +150°C junction temperature.
The device exhibits low dynamic impedance (7.0 Ω) at IZT = 28.8 mA and tight knee behavior (IZK = 0.25 mA, ZZK = 550 Ω), supporting accurate regulation even at low bias currents - critical for low-power sensing and standby-mode protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 13.0 V ±5% at IZT = 28.8 mA, TC = 30°C - defines nominal regulation point for feedback networks |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power before thermal derating begins |
| Dynamic Impedance ZZT | 7.0 Ω at IZT = 28.8 mA - determines output voltage variation under load transients |
| Knee Current IZK | 0.25 mA - minimum current needed to enter useful regulation region |
| Thermal Resistance θJT | 30°C/W junction-to-TAB1 - quantifies thermal path efficiency to PCB heat sink |
| ESD Rating | >16 kV per Human Body Model - ensures robustness during automated handling and board assembly |
| Reverse Leakage IR | <1 µA at VR = 10.4 V - limits quiescent current in high-impedance bias networks |
Pinout & Package

IC Role / Device Role / Timing Role: Low-quiescent-current voltage reference replacing higher-cost bandgap ICs. Use Value: Sub-1 µA reverse leakage at 10.4 V extends battery life while maintaining 13 V accuracy within ±5%. | Use Scenario: Supplying excitation voltage to RTD or strain gauge bridges in process control transmitters. IC Role / Device Role / Timing Role: Stable, thermally anchored voltage source referenced to system ground. Use Value: 30°C/W θJT and metallic TAB 1 enable stable operation at ambient up to +85°C without external heatsinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | DO-41 through-hole package; 12 V nominal; 1 W rating; no metallic thermal tab | Requires PCB footprint redesign and lacks thermal performance for 3 W operation | Use only where manual assembly or legacy through-hole design mandates DO-41 form factor |
| BZX84-C13 | SOT-23 package; 13 V nominal; 300 mW rating; 30 Ω ZZT; no integrated heat sink | Insufficient power handling for sustained 3 W regulation; limited thermal margin | Select only for low-duty-cycle clamping or space-constrained designs where 300 mW suffices |
Compared with 1N4742A and BZX84-C13, the 1PMT5928AE3/TR7 delivers 3× the power rating of the SOT-23 part and 3× the thermal capability of the DO-41 part - making it the sole option among the three capable of continuous 3 W regulation with validated PCB thermal coupling via TAB 1.

FAQ
What is the Zener voltage tolerance for 1PMT5928AE3/TR7?
The 1PMT5928AE3/TR7 has a standard Zener voltage tolerance of ±5% at 13.0 V, measured at IZT = 28.8 mA and case temperature TC = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the E3/TR7 variant specifies ±5% per Microsemi's MSC0995 datasheet revision F.
How is thermal management implemented in the 1PMT5928AE3/TR7 package?
The 1PMT5928AE3/TR7 uses the Powermite® package with a full metallic bottom and integral locking tab (TAB 1) that serves as both cathode and primary thermal conduction path. Its specified thermal resistance is 30°C/W junction-to-TAB1, requiring direct soldering of TAB 1 to a copper pour for effective heat dissipation at its full 3.0 W rating.
Can the 1PMT5928AE3/TR7 replace a 1N4742A in existing designs?
No direct replacement is possible without layout changes: the 1PMT5928AE3/TR7 is a surface-mount Powermite® device with TAB 1 cathode, while the 1N4742A is a through-hole DO-41 diode rated for only 1 W. The 1PMT5928AE3/TR7 requires PCB redesign for SMT pads and thermal copper, and offers higher power, better thermal performance, and superior ESD rating than the 1N4742A.
What is the maximum reverse leakage current for 1PMT5928AE3/TR7 at 10.4 V?
Per the MSC0995 datasheet, the maximum reverse leakage current IR for 1PMT5928AE3/TR7 is 1 µA at VR = 10.4 V and TL = 30°C. This low leakage supports energy-efficient operation in battery-powered or high-impedance bias networks where quiescent current must be minimized.
Is the 1PMT5928AE3/TR7 compatible with standard SMT assembly processes?
Yes - the 1PMT5928AE3/TR7 is supplied in EIA-481 compliant tape-and-reel format (7″ reel, 3,000 pieces) and features a locking tab and full metallic bottom engineered for compatibility with automated pick-and-place equipment and reflow soldering. Its design eliminates solder flux entrapment and ensures mechanical stability during placement and thermal cycling.
