Product details
Overview
1PMT5929BE3/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 DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5929BE3/TR7 datasheet, 1PMT5929BE3/TR7 pinout, 1PMT5929BE3/TR7 application, or 1PMT5929BE3/TR7 equivalent, key selection criteria include its 15 V nominal Zener voltage, 3.0 W thermal capability via metallic tab, DO-216 mechanical outline, ESD rating >16 kV HBM, and compatibility with automated SMT placement equipment.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations and temperature shifts. Its junction-to-tab thermal resistance of 30°C/W enables effective heat transfer to the PCB copper pad through the full metallic bottom and locking tab - critical for sustained 3.0 W operation without derating in compact layouts.
The device exhibits low knee impedance (≤9.0 Ω) and tight regulation at IZT = 25 mA, with reverse leakage held to ≤600 µA at VR = 11.4 V. Its DO-216 footprint supports high-density board designs while eliminating solder flux entrapment due to the fully metallized base.
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 robust voltage control in space-constrained power stages |
| Dynamic Impedance (ZZT) | 9.0 Ω at IZT = 25 mA - ensures minimal output voltage deviation under load transients |
| Reverse Leakage (IR) | ≤600 µA at VR = 11.4 V - guarantees low standby current in battery-backed or low-power systems |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows direct thermal coupling to PCB copper for passive cooling |
| ESD Rating | >16 kV per Human Body Model - provides inherent protection against handling-induced discharge events |

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 axial package with higher thermal resistance (50°C/W) | Requires through-hole mounting and larger board area; unsuitable for high-density SMT designs | Select 1N5929B only if legacy through-hole assembly or manual prototyping is required |
| MMSZ5245B | 15 V Zener in SOD-123 package, rated for 500 mW only and no metallic thermal tab | Limited to low-power biasing or signal-level clamping; cannot sustain 3.0 W continuous dissipation | Choose MMSZ5245B for space-constrained signal conditioning where power handling is not required |
Compared with 1N5929B and MMSZ5245B, the 1PMT5929BE3/TR7 uniquely combines 3.0 W power capability, SMT compatibility, and low thermal resistance in a single DO-216 package - making it the only option among the three suitable for high-reliability, thermally demanding power rail stabilization.

FAQ
What is the Zener voltage tolerance for the 1PMT5929BE3/TR7?
The 1PMT5929BE3/TR7 has a standard Zener voltage tolerance of ±5% at 15 V nominal, measured at IZT = 25 mA and TC = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the E3/TR7 variant uses the standard ±5% grade. This tolerance directly impacts regulation accuracy in feedback loops and voltage reference applications.
How is thermal management handled in the 1PMT5929BE3/TR7 package?
The 1PMT5929BE3/TR7 uses a Powermite® package with a full metallic bottom and integral locking tab (TAB 1) that serves as both cathode and primary thermal path. Its junction-to-tab thermal resistance is 30°C/W, enabling efficient heat transfer to the PCB copper pad. Proper layout - including adequate copper area under TAB 1 - is essential to sustain its rated 3.0 W dissipation.
Is the 1PMT5929BE3/TR7 compatible with automated SMT assembly?
Yes, the 1PMT5929BE3/TR7 is specifically designed for automated insertion equipment. It ships in EIA-481 compliant tape-and-reel format (3,000 pieces per 7-inch reel), features a DO-216 outline optimized for pick-and-place nozzles, and includes a locking tab that prevents rotation during placement - ensuring high first-pass yield in high-volume manufacturing.
What is the maximum reverse leakage current for the 1PMT5929BE3/TR7?
The 1PMT5929BE3/TR7 specifies a maximum reverse leakage current of 600 µA at VR = 11.4 V and TL = 30°C. This low leakage supports energy-efficient operation in battery-powered or always-on monitoring circuits, and remains stable across its -55°C to +150°C operating junction temperature range.
Does the 1PMT5929BE3/TR7 meet any ESD immunity standards?
Yes, the 1PMT5929BE3/TR7 is rated for >16 kV electrostatic discharge per the Human Body Model (HBM), as confirmed in the MSC0995 datasheet. This high ESD rating reduces susceptibility to damage during handling and board assembly, enhancing field reliability in environments with uncontrolled static discharge risks.
