Product details
Overview
1PMT5929C/TR7 from Microsemi is a 15 V, ±1% tolerance Zener diode in the Powermite® surface-mount 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 11.4 mA maximum Zener current. It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5929C/TR7 datasheet, 1PMT5929C/TR7 pinout, 1PMT5929C/TR7 application, or 1PMT5929C/TR7 equivalent, key selection criteria include its ±1% Zener voltage tolerance (suffix C), 3.0 W thermal capability via metallic tab, DO-216 mechanical outline, and ESD rating >16 kV HBM - critical for ruggedized power supply design.
Technical Context
This device operates as a two-terminal voltage-regulating diode with cathode designated by TAB 1. Its Zener voltage is specified at 15.0 V ±1% under 25 mA test current (IZT) with junction temperature maintained at 30°C, and exhibits low reverse leakage (≤1 µA at VR = 11.4 V).
The Powermite® package integrates a full metallic bottom and locking tab that functions as both mechanical anchor and thermal path to PCB copper, achieving 30°C/W junction-to-tab thermal resistance - enabling stable regulation under sustained 3.0 W dissipation when mounted on adequate copper area.
Key Specifications

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 nominal Zener voltage but ±5% tolerance (no suffix); 10.0 Ω ZZT; 3.0 W rating in DO-41 through-hole package | Requires manual placement and wave soldering; lacks metallic thermal tab | Select when cost sensitivity outweighs precision and thermal performance; not suitable for high-density SMT designs |
| BZX84-C15 | 15 V ±5% Zener in SOT-23; 500 mW rating; 30 Ω dynamic impedance; 350 mW max power at TA = 25°C | Limited to low-power bias/reference roles; cannot sustain 3.0 W surges | Choose only for space-constrained, low-current applications where 3.0 W capability is unnecessary |
Compared with 1PMT5929C/TR7, 1N5929B offers lower cost but sacrifices tolerance and thermal performance, while BZX84-C15 saves board area yet fails to meet 3.0 W clamping requirements - making 1PMT5929C/TR7 the sole option for precision, high-power SMT Zener regulation.

FAQ
What is the Zener voltage tolerance of 1PMT5929C/TR7?
The 1PMT5929C/TR7 has a Zener voltage tolerance of ±1%, indicated by the "C" suffix in the part number. This is tighter than the standard ±5% version (1PMT5929B) and enables direct use in precision voltage reference circuits without calibration. The 15.0 V rating is measured at 25 mA test current with TAB 1 held at 30°C, per Microsemi Note 202.
How is thermal management handled for 1PMT5929C/TR7?
1PMT5929C/TR7 relies on its metallic TAB 1 for thermal conduction, achieving 30°C/W junction-to-tab resistance. To sustain its full 3.0 W rating, TAB 1 must be soldered to ≥1 cm² of 2-ounce copper on the PCB. The locking tab mechanically anchors the device while enhancing heat transfer - unlike plastic-bodied SOD-123 or SOT-23 packages.
Is 1PMT5929C/TR7 compatible with automated SMT assembly?
Yes, 1PMT5929C/TR7 is fully compatible with automated surface-mount insertion equipment. Its Powermite® package features a unique locking tab and full metallic bottom that prevent rotation and flux entrapment during reflow. It ships in EIA-481 tape-and-reel format (7-inch reel, 3,000 pieces), optimized for high-speed pick-and-place systems.
What is the maximum reverse leakage current for 1PMT5929C/TR7?
The maximum reverse leakage current for 1PMT5929C/TR7 is 1 µA at a reverse voltage of 11.4 V (VR), as specified in the Electrical Characteristics table. This low leakage ensures minimal loading of high-impedance bias networks and preserves accuracy in precision reference applications where 1PMT5929C/TR7 is deployed.
Does 1PMT5929C/TR7 meet any ESD standards?
Yes, 1PMT5929C/TR7 is rated for >16 kV per the Human Body Model (HBM) ESD standard. This high ESD immunity supports safe handling in non-ESD-controlled manufacturing environments and improves field reliability in systems exposed to static discharge - a key advantage over generic Zener diodes lacking formal HBM characterization.
