Product details
Overview
1PMT5929E3/TR13 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 - used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the 1PMT5929E3/TR13 datasheet, 1PMT5929E3/TR13 pinout, 1PMT5929E3/TR13 application, or 1PMT5929E3/TR13 equivalent, key selection criteria include Zener voltage accuracy, power derating behavior above 60°C, low reverse leakage (≤1 µA at 11.4 V), ESD robustness (>16 kV HBM), and compatibility with automated SMT assembly on DO-216 footprint.
Technical Context
This device operates as a two-terminal voltage reference with cathode designated by TAB 1, requiring no external biasing. Its full metallic bottom and integral heat sink locking tab enable direct thermal conduction to PCB copper, supporting stable regulation under transient load conditions.
The 1PMT5929E3/TR13 exhibits tight knee characteristics (IZK = 0.25 mA, ZZK = 600 Ω) and low forward voltage (1.2 V @ 200 mA), making it suitable for bidirectional clamping and low-dropout shunt regulation where reverse leakage and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.0 V ±5% at IZT = 25 mA, TL = 30°C - defines nominal regulation point with predictable deviation across temperature and current |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power handling before thermal shutdown or parameter drift |
| Dynamic Impedance (ZZT) | 9.0 Ω at IZT = 25 mA - determines output voltage variation under load current changes (ΔVZ ≈ ΔIZ × 9 Ω) |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables thermal design using PCB copper area as heatsink; 10°C rise per 0.33 W dissipated |
| Reverse Leakage (IR) | ≤1 µA at VR = 11.4 V - ensures minimal quiescent current in standby regulation or sensing circuits |
| ESD Rating | >16 kV per Human Body Model - supports robustness in handling and board-level ESD events without degradation |
Pinout & Package
Package: Powermite® (DO-216), molded surface-mount package with full metallic bottom and integral heat sink locking tab; cathode identified by TAB 1; weight ≈ 0.016 g; mounting position unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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, but in DO-41 through-hole package; higher thermal resistance (~50°C/W); no metallic bottom or locking tab | Requires manual or wave soldering; unsuitable for high-density SMT layouts or automated insertion | Select 1N5929B only when legacy through-hole assembly or higher single-pulse surge capability is required |
| BZX84-C15 | 15 V Zener in SOT-23; rated for 300 mW only; dynamic impedance ~30 Ω; ESD rating unspecified | Limited to low-power signal-level clamping; cannot sustain 3.0 W continuous dissipation | Choose BZX84-C15 only for space-constrained signal conditioning where power handling is not required |

FAQ
What is the Zener voltage tolerance for 1PMT5929E3/TR13?
The 1PMT5929E3/TR13 has a standard Zener voltage tolerance of ±5% at 15.0 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 respectively, but the E3/TR13 variant uses the standard ±5% grade.
Can 1PMT5929E3/TR13 be used in place of through-hole Zeners like 1N5929B?
Yes, the 1PMT5929E3/TR13 provides identical 15 V Zener functionality but in a surface-mount Powermite® package. It requires no PCB layout change for footprint adaptation, though thermal pad design must accommodate its 3.0 W rating and 30°C/W junction-to-TAB1 thermal resistance - unlike the higher thermal resistance of 1N5929B.
What is the maximum reverse leakage current for 1PMT5929E3/TR13?
The maximum reverse leakage current for 1PMT5929E3/TR13 is 1 µA at a reverse voltage of 11.4 V (76% of nominal VZ), specified at TL = 30°C. This low leakage supports energy-efficient designs in battery-powered or always-on systems where standby current must be minimized.
How does the Powermite® package improve thermal performance of 1PMT5929E3/TR13?
The Powermite® package of the 1PMT5929E3/TR13 features a full metallic bottom and integral heat sink locking tab that directly conducts heat from the junction to the PCB copper. With a thermal resistance of 30°C/W junction-to-TAB1, it achieves significantly better thermal management than standard SOD-123 or SOT-23 packages - enabling full 3.0 W dissipation without external heatsinks.
Is 1PMT5929E3/TR13 compatible with lead-free reflow soldering processes?
Yes, the 1PMT5929E3/TR13 is qualified for lead-free reflow soldering per J-STD-020. Its Powermite® package withstands peak temperatures up to 260°C for 30 seconds, and the full metallic bottom ensures uniform thermal transfer during reflow - eliminating flux entrapment risks common in plastic-bodied SMT diodes.
