Product details
Overview
1PMT5929C/TR13 from Microsemi is a 15 V, ±1% 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-tab. It serves as a precision voltage reference or overvoltage clamp in power supply regulation circuits.
For engineers reviewing the 1PMT5929C/TR13 datasheet, 1PMT5929C/TR13 pinout, 1PMT5929C/TR13 application, or 1PMT5929C/TR13 equivalent, key selection criteria include its tight 1% Zener voltage tolerance, low 9.0 Ω dynamic impedance, ESD rating >16 kV HBM, full metallic bottom for flux-free assembly, and compatibility with automated insertion equipment.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its Powermite® package features an integral heat sink locking tab and full metallic bottom-enabling efficient thermal conduction to the PCB and eliminating solder flux entrapment during reflow.
The device is characterized at TL = 30°C with IZT = 25 mA, VZ = 15.0 V (±1%), ZZT = 9.0 Ω, IZK = 0.25 mA, and IR ≤ 1 µA at VR = 11.4 V. Junction-to-tab thermal resistance is 30°C/W, supporting reliable operation up to +150°C storage and junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.0 V ±1% at IZT = 25 mA - enables precise voltage clamping or reference within ±0.15 V tolerance |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - supports high-energy transient suppression without derating in compact layouts |
| Dynamic Impedance (ZZT) | 9.0 Ω at IZT = 25 mA - ensures minimal output voltage variation under dynamic load changes |
| Reverse Leakage (IR) | ≤1 µA at VR = 11.4 V - guarantees low standby power loss in battery-backed or low-power systems |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows direct thermal path to copper pour or heatsink pad on PCB |
| ESD Rating | >16 kV per Human Body Model - provides robust handling and system-level ESD immunity without external protection |
Pinout & Package
Package: Powermite® (DO-216AA), molded surface-mount package with full metallic bottom and integral heat sink locking tab. Cathode is 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 thermal pad for rated 3.0 W operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15LT1G | 250 mW SOT-23 package, 15 V ±5%, ZZT = 30 Ω at 5 mA | Limited to low-power signal-level clamping; not suitable for 3 W transient absorption | Select when board space is critical and power dissipation < 0.3 W required |
| SMBJ15A | TVS diode, 15 V standoff, 22.5 V clamping, 600 W peak pulse power | Designed for fast transient suppression (tP = 1 ns), not precision DC regulation | Select for ESD/EFT surge protection where regulation accuracy is secondary |
Compared with BZX84-C15LT1G and SMBJ15A, the 1PMT5929C/TR13 uniquely combines 1% DC voltage accuracy, 3.0 W continuous dissipation, and thermal design optimized for PCB-mounted heat sinking-making it irreplaceable in regulated power supply references requiring both precision and power robustness.

FAQ
What is the Zener voltage tolerance for 1PMT5929C/TR13?
The "C" suffix in 1PMT5929C/TR13 denotes ±1% Zener voltage tolerance at IZT = 25 mA and TL = 30°C. This is tighter than the standard ±5% (B suffix) and supports precision regulation applications where output stability is critical. The 15.0 V nominal value therefore ranges from 14.85 V to 15.15 V under specified test conditions.
How is thermal management implemented for 1PMT5929C/TR13?
1PMT5929C/TR13 uses its metallic TAB 1 as the primary thermal conduction path. With a junction-to-tab thermal resistance of 30°C/W, optimal cooling requires soldering TAB 1 to a minimum 100 mm² copper pad connected to internal ground or power planes. Derating is required above 60°C tab temperature to maintain 3.0 W dissipation capability.
Can 1PMT5929C/TR13 replace through-hole Zener diodes like 1N5245B?
Yes, 1PMT5929C/TR13 can functionally replace 1N5245B (15 V, ±5%, 500 mW) in many designs-but only if PCB layout accommodates the Powermite® footprint and thermal pad. Its 3.0 W rating and ±1% tolerance offer superior performance, though layout redesign is required due to different mounting geometry and thermal interface requirements.
What does the "TR13" suffix indicate in 1PMT5929C/TR13?
The "TR13" suffix specifies tape-and-reel packaging per EIA-481 standard on a 13-inch reel containing 12,000 units. This format is optimized for high-volume automated SMT placement. The "TR" denotes tape-and-reel, and "13" identifies the reel diameter-not a revision or performance variant.
Is 1PMT5929C/TR13 suitable for use in automotive applications?
Yes, 1PMT5929C/TR13 meets automotive-grade operating temperature requirements (−55°C to +150°C junction/storage), has >16 kV HBM ESD rating, and is qualified for harsh environments. It is commonly used in body control modules and powertrain subsystems for load dump protection and reference stabilization-provided thermal design and board-level qualification align with AEC-Q101 guidelines.
