Product details
Overview
1PMT5929CE3/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 600 µA max reverse leakage at 11.4 V. It serves as a precision voltage reference or overvoltage clamp in compact DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5929CE3/TR7 datasheet, 1PMT5929CE3/TR7 pinout, 1PMT5929CE3/TR7 application, or 1PMT5929CE3/TR7 equivalent, key selection criteria include its 15 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heatsinking, low 9.0 Ω Zener impedance, ESD rating >16 kV HBM, and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This device operates as a two-terminal voltage-regulating diode with cathode designated by TAB 1. Its Zener breakdown is specified at 25 mA (IZT), with knee current IZK = 0.25 mA and corresponding knee impedance ZZK = 600 Ω - indicating stable regulation onset well below rated current.
The Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction from junction to PCB pad, achieving 30°C/W junction-to-TAB thermal resistance. It supports operation across –55°C to +150°C junction temperature range and is qualified for automatic insertion equipment handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V ±5% at IZT = 25 mA - defines stable regulation point for feedback or clamping circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-energy transient suppression without external heatsink |
| Dynamic Impedance (ZZT) | 9.0 Ω at IZT = 25 mA - ensures minimal output voltage variation under load current changes |
| Reverse Leakage (IR) | ≤600 µA at VR = 11.4 V - guarantees low quiescent current in standby or high-impedance sensing nodes |
| Thermal Resistance | 30°C/W junction-to-TAB - allows direct thermal path to PCB copper for reliable power handling |
| ESD Rating | >16 kV per Human Body Model - provides robust protection against handling-induced electrostatic discharge |
| Package | Powermite® (DO-216) - surface-mount, molded, full-metallic bottom, cathode on TAB 1 |
Pinout & Package
Powermite® (DO-216) package: surface-mount, molded plastic body with full metallic bottom and integral heat-sink locking tab; cathode terminal is TAB 1; anode is the opposite lead; mounting orientation is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and voltage reference node; must be connected to ground or low-impedance return path |
| Lead 2 | Anode | Current entry point during forward bias; connects to positive rail or regulated node in Zener configuration |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling comparable to larger through-hole Zeners |
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and void-free solder joints |
| Integral heat-sink locking tab | Provides mechanical anchoring and low-thermal-resistance path from junction to PCB copper |
| ESD robustness | >16 kV HBM rating reduces risk of field failure during board handling and system integration |

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, 1 W rating, DO-41 package, no metallic thermal tab | Limited to lower-power linear regulators; lacks integrated heatsinking for sustained 3 W operation | Select when cost sensitivity outweighs thermal performance and board space is not constrained |
| BZX84-C15 | 15 V nominal, 300 mW rating, SOT-23 package, 16 kV HBM ESD | Suitable only for signal-level clamping; insufficient for power-rail transient suppression | Choose for ultra-compact, low-current bias/reference use where 3 W capability is unnecessary |
Compared with 1N4744A and BZX84-C15, the 1PMT5929CE3/TR7 uniquely combines 15 V Zener voltage, 3.0 W power handling, and Powermite® thermal design - enabling robust voltage regulation in space-constrained, high-reliability power systems where thermal management and ESD resilience are critical.

FAQ
What is the Zener voltage tolerance for 1PMT5929CE3/TR7?
The 1PMT5929CE3/TR7 has a standard Zener voltage tolerance of ±5% at 15 V nominal, measured at 25 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the CE3 designation confirms the ±5% version. This tolerance directly impacts regulation accuracy in feedback and reference applications.
How is thermal performance achieved in the 1PMT5929CE3/TR7 package?
The 1PMT5929CE3/TR7 achieves thermal performance via its Powermite® package: a full metallic bottom and integral locking tab provide a low-resistance thermal path from junction to PCB, resulting in 30°C/W junction-to-TAB thermal resistance. This allows safe 3.0 W dissipation at TAB 1 = 60°C - far exceeding typical SMT Zener capabilities.
Is 1PMT5929CE3/TR7 compatible with automated SMT assembly processes?
Yes, the 1PMT5929CE3/TR7 is explicitly designed for compatibility with automatic insertion equipment and standard SMT reflow processes. Its Powermite® package features a mold release geometry and flat metallic base that prevent flux entrapment, and it ships in EIA-481 tape-and-reel format (7″ reel, 3,000 pcs), supporting high-yield pick-and-place operations.
What is the maximum reverse leakage current for 1PMT5929CE3/TR7?
The maximum reverse leakage current for 1PMT5929CE3/TR7 is 600 µA at a reverse voltage of 11.4 V, measured at TL = 30°C. This low leakage ensures minimal loading on high-impedance nodes such as op-amp inputs or microcontroller ADC references, preserving signal fidelity and power efficiency in battery-powered designs.
Does 1PMT5929CE3/TR7 have ESD protection built-in?
Yes, the 1PMT5929CE3/TR7 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), as confirmed in the official Microsemi datasheet. This intrinsic robustness eliminates the need for external ESD protection in many applications and enhances reliability during board handling, testing, and field operation - especially in ungrounded or portable systems.
