Product details
Overview
1PMT5929AE3/TR7 from Microsemi is a 15 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 9.0 Ω dynamic impedance at 25 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 ESD-protected signal conditioning circuits.
For engineers reviewing the 1PMT5929AE3/TR7 datasheet, 1PMT5929AE3/TR7 pinout, 1PMT5929AE3/TR7 application, or 1PMT5929AE3/TR7 equivalent, key selection criteria include zener voltage tolerance, power derating above 60°C, knee current (IZK = 0.25 mA), reverse leakage (IR ≤ 1 µA at VR = 12.2 V), and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This device operates as a two-terminal voltage-reference diode with cathode designated by TAB 1. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and eliminate solder flux entrapment during reflow.
Designed for stable operation across -55°C to +150°C junction temperature range, it delivers low reverse leakage (≤1 µA at 12.2 V) and ESD robustness (>16 kV HBM), enabling use in industrial power rails and automotive body electronics where thermal cycling and electrostatic stress are present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 15 V ±5% at IZT = 25 mA, TL = 30°C - defines nominal clamping/reference level under standard test conditions |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum steady-state power before thermal shutdown or degradation |
| Dynamic Impedance | 9.0 Ω at IZT = 25 mA - indicates voltage regulation stability under small-signal AC perturbations |
| Knee Current | 0.25 mA - minimum current required to enter defined zener breakdown region |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies thermal path efficiency from die to mounting pad |
| ESD Rating | >16 kV per Human Body Model - ensures survivability during handling and board-level ESD events |
| Reverse Leakage | ≤1 µA at VR = 12.2 V - confirms low off-state current for high-impedance bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5929B | Same 15 V zener voltage and ±5% tolerance, but in DO-41 through-hole package; no metallic bottom or locking tab; thermal resistance ~65°C/W. | Requires manual or wave soldering; unsuitable for high-density SMT layouts or automated insertion. | Select 1N5929B only when legacy through-hole assembly or higher thermal margin at lower power is acceptable. |
| BZX84-C15 | 15 V SOT-23 Zener; 300 mW rating; 15 Ω dynamic impedance; 100 nA reverse leakage at 12 V; no integrated heat sink tab. | Limited to low-power biasing; cannot replace 1PMT5929AE3/TR7 in 3 W clamping roles without parallel devices or heatsinking. | Choose BZX84-C15 for space-constrained logic-level references, not for power rail protection. |
Compared with 1N5929B and BZX84-C15, the 1PMT5929AE3/TR7 uniquely combines 3 W SMT power handling, 30°C/W thermal resistance, and EIA-481 tape-and-reel compatibility-making it the only option for high-reliability, high-power, fully automated production of industrial power interfaces.

The 1PMT5929AE3/TR7 has a standard zener voltage tolerance of ±5% at 15 V, measured at 25 mA test current and TAB 1 temperature of 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the base part number 1PMT5929AE3/TR7 specifies ±5%.
How is thermal performance managed in the 1PMT5929AE3/TR7 package?
The 1PMT5929AE3/TR7 uses the Powermite® package with a full metallic bottom and integral locking tab that acts as a heat sink. Its junction-to-TAB1 thermal resistance is 30°C/W, enabling reliable 3.0 W operation when TAB 1 is maintained at ≤60°C-requiring adequate PCB copper area under TAB 1 for heat spreading.
Is the 1PMT5929AE3/TR7 compatible with automated SMT assembly processes?
Yes, the 1PMT5929AE3/TR7 is designed for compatibility with automatic insertion equipment and is supplied in EIA-481 compliant tape-and-reel format (7-inch reel, 3,000 pieces). Its Powermite® package geometry and cathode marking ensure accurate pick-and-place and optical inspection alignment.
What is the maximum reverse leakage current for 1PMT5929AE3/TR7?
The 1PMT5929AE3/TR7 exhibits a maximum reverse leakage current of 1 µA at a reverse voltage of 12.2 V (82% of nominal 15 V zener voltage), measured at TL = 30°C. This low leakage supports high-impedance bias networks and precision reference applications.
Does the 1PMT5929AE3/TR7 meet any ESD immunity standards?
Yes, the 1PMT5929AE3/TR7 is rated for >16 kV per the Human Body Model (HBM) ESD test, as specified in the MSC0995 datasheet. This rating reflects its robustness during handling, PCB assembly, and operation in electrically noisy environments.
