Product details
Overview
1PMT5934A/TR13 from Microsemi is a 24 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 19 Ω dynamic impedance at 15.6 mA test current and 700 µA max reverse leakage at 18.2 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5934A/TR13 datasheet, 1PMT5934A/TR13 pinout, 1PMT5934A/TR13 application, or 1PMT5934A/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance, and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation across varying load currents. Its Powermite® package features a full metallic bottom for flux-free soldering and an integral locking tab acting as both mechanical anchor and heat sink, enabling direct thermal conduction from junction to PCB copper via TAB 1.
The device exhibits tight voltage control with 24 V nominal Zener voltage measured at 15.6 mA (IZT), 19 Ω dynamic impedance (ZZT), and 700 µA maximum reverse leakage (IR) at 18.2 V (VR). Thermal resistance of 30°C/W from junction to TAB 1 supports reliable operation up to +150°C junction temperature.
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 |
|---|---|---|---|
| SMCJ24A | TVS diode (unidirectional), 30 kW peak pulse power, 26.7 V standoff, 38.9 V clamping - not a precision Zener | Transient suppression only; unsuitable for voltage reference or regulation | Select only for surge protection; not interchangeable for regulation tasks |
| BZX84-C24 | SOT-23 Zener, 24 V ±5%, 300 mW Pd, 85 Ω ZZT - lower power, higher impedance, no integral heat sink | Limited to low-power signal-level references; cannot handle 3 W continuous dissipation | Choose for space-constrained low-power designs; avoid where thermal performance or power margin is critical |
Compared with SMCJ24A and BZX84-C24, the 1PMT5934A/TR13 uniquely combines 3.0 W continuous Zener regulation, 30°C/W thermal resistance via TAB 1, and EIA-481 tape-and-reel compatibility - making it suitable for industrial power rail stabilization where precision, power, and manufacturability coexist.

What is the Zener voltage tolerance for 1PMT5934A/TR13?
The 1PMT5934A/TR13 has a nominal Zener voltage of 24 V with a standard tolerance of ±5%, as specified in the MSC0995 datasheet. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request. Voltage is measured at IZT = 15.6 mA with TAB 1 held at 30°C for 20 seconds prior to reading.
How is thermal management implemented in the 1PMT5934A/TR13 package?
The 1PMT5934A/TR13 uses its metallic TAB 1 as the primary thermal conduction path, with a specified junction-to-TAB thermal resistance of 30°C/W. This allows direct mounting to PCB copper pours for effective heat dissipation. The full metallic bottom and locking tab enhance thermal transfer while preventing solder flux entrapment during reflow.
Is the 1PMT5934A/TR13 compatible with automated SMT assembly?
Yes, the 1PMT5934A/TR13 is fully compatible with automated surface-mount assembly. It is supplied in EIA-481 compliant tape-and-reel format (13-inch reel: 12,000 pieces), and its Powermite® package geometry supports reliable pick-and-place and reflow soldering. The locking tab ensures mechanical stability during placement and thermal cycling.
What is the maximum reverse leakage current for 1PMT5934A/TR13?
The maximum reverse leakage current (IR) for 1PMT5934A/TR13 is 700 µA at a reverse voltage (VR) of 18.2 V, measured at TL = 30°C. This low leakage supports stable operation in high-impedance reference and clamping circuits where standby current must be minimized.
Does the 1PMT5934A/TR13 meet any ESD immunity standards?
Yes, the 1PMT5934A/TR13 is rated for >16 kV per the Human Body Model (HBM) ESD test, as confirmed in the MSC0995 datasheet. This high ESD rating ensures robustness during handling, board assembly, and end-use in electrically noisy industrial environments.
