Product details
Overview
1PMT5928E3/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 DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5928E3/TR7 datasheet, 1PMT5928E3/TR7 pinout, 1PMT5928E3/TR7 application, or 1PMT5928E3/TR7 equivalent, key selection criteria include Zener voltage tolerance, power derating above 60°C, reverse leakage at specified VR, knee current behavior, and compatibility with automated SMT placement due to its DO-216 outline and integral locking tab.
Technical Context
This device operates as a silicon planar Zener diode with controlled avalanche breakdown at nominal 13 V. 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 characterized at TL = 30°C with IZT = 28.8 mA; Zener voltage is measured 20 seconds after DC current application, and dynamic impedance (ZZT) is derived using 60 Hz RMS AC current equal to 10% of IZT superimposed on DC bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 13.0 V ±5% at IZT = 28.8 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 | 7.0 Ω at IZT - determines output voltage variation under load current transients |
| Knee Current IZK | 0.25 mA at VZ × 0.75 - specifies minimum current for usable regulation onset |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt dissipated into PCB copper |
| ESD Rating | >16 kV HBM - ensures robustness during handling and board assembly |
| Reverse Leakage IR | 1 µA max at VR = 10.4 V - limits standby power loss in high-impedance bias networks |
Pinout & Package
Package: Powermite® (DO-216AA), molded surface-mount package with full metallic bottom and integral locking tab; cathode designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and electrical cathode connection; must be soldered to copper pour for thermal compliance |
| Lead 2 | Anode | Standard anode connection; electrically isolated from TAB 1; used for circuit return path |
Key Features
| Feature | Design Value |
|---|---|
| Integral heat sink locking tab | Mechanically anchors device during reflow and conducts >80% of heat directly from junction to PCB copper |
| Full metallic bottom | Eliminates solder flux entrapment risk and improves thermal interface reliability vs. plastic-bottom SMD packages |
| ESD hardness >16 kV HBM | Enables safe handling without ionized air or wrist straps in standard 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 |
|---|---|---|---|
| 1N5349B | Same 13 V nominal, but in DO-204AL (DO-41) through-hole package; 5 W rating; higher ZZT (10 Ω) | Requires PCB through-hole mounting; unsuitable for high-density SMT layouts | Select when higher power margin is needed and through-hole assembly is acceptable |
| BZX84-C13 | 13 V SOT-23 package; 300 mW rating; ±5% tolerance; ZZT = 25 Ω at 5 mA | Limited to low-power signal-level clamping; cannot sustain 3 W continuous dissipation | Select for space-constrained logic-level protection where power stress is minimal |

FAQ
What is the Zener voltage tolerance for 1PMT5928E3/TR7?
The 1PMT5928E3/TR7 has a standard Zener voltage tolerance of ±5% at 13.0 V, measured at IZT = 28.8 mA with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the base part number 1PMT5928E3/TR7 ships with ±5%.
How is thermal performance defined for 1PMT5928E3/TR7?
The 1PMT5928E3/TR7 has a junction-to-TAB1 thermal resistance of 30°C/W. This means each watt dissipated raises the junction temperature 30°C above TAB 1 temperature. For reliable operation at 3.0 W, TAB 1 must be maintained at ≤60°C-requiring adequate PCB copper area and thermal vias beneath TAB 1.
Can 1PMT5928E3/TR7 be used in place of through-hole Zeners like 1N5349B?
No-1PMT5928E3/TR7 is not a drop-in replacement for 1N5349B due to different packages (Powermite® DO-216 vs. DO-41), thermal paths, and mounting methods. While both are 13 V Zeners, substituting requires PCB layout revision, thermal redesign, and validation of transient response under identical conditions.
What does the "E3/TR7" suffix indicate in 1PMT5928E3/TR7?
The "E3" denotes tape-and-reel packaging per EIA-481 standard, and "TR7" specifies 7-inch reels containing 3,000 units. This packaging format ensures compatibility with automated SMT placement equipment and supports high-volume manufacturing flow.
Is 1PMT5928E3/TR7 suitable for use in automotive applications?
Yes-the 1PMT5928E3/TR7 meets automotive-grade requirements with operating junction temperature range of –55°C to +150°C, >16 kV HBM ESD rating, and robust Powermite® package qualified for vibration and thermal cycling. It is commonly deployed in automotive body control modules and power distribution units for rail clamping.
