It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5934CE3/TR13 datasheet, 1PMT5934CE3/TR13 pinout, 1PMT5934CE3/TR13 application, or 1PMT5934CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance (≤400 Ω), and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This device operates as a two-terminal voltage-regulating diode with sharp Zener breakdown at 24 V nominal. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and mechanical stability during reflow soldering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5354B | Same 24 V ±5%, but DO-204AL package; 3.0 W rating at 75°C ambient; 35 Ω ZZT vs. 19 Ω | Larger footprint; higher thermal resistance (50°C/W); less suitable for dense layouts | Select when legacy through-hole compatibility or higher ambient temperature derating is required |

FAQ
What is the Zener voltage tolerance for 1PMT5934CE3/TR13?
The 1PMT5934CE3/TR13 has a nominal Zener voltage of 24 V with a standard tolerance of ±5%. This tolerance is confirmed in the MSC0995.PDF datasheet under Note 1, which specifies that the "C" suffix denotes ±5% tolerance. The device is also available in tighter tolerances (±2% and ±1%) with suffixes "C" and "D", respectively-but the "CE3" suffix in 1PMT5934CE3/TR13 explicitly indicates the ±5% version.
How is thermal management handled in the 1PMT5934CE3/TR13 package?
The 1PMT5934CE3/TR13 uses the Powermite® package with a full metallic bottom and integral locking tab acting as the cathode (TAB 1). Its specified thermal resistance is 30°C/W junction-to-TAB, meaning effective heat transfer requires direct soldering of TAB 1 to a thermally robust PCB copper area. This design eliminates flux entrapment and provides a low-resistance thermal path-critical for sustaining 3.0 W dissipation without external heatsinking.
What is the maximum reverse leakage current for 1PMT5934CE3/TR13 and at what voltage is it measured?
The maximum reverse leakage current for 1PMT5934CE3/TR13 is 700 µA, measured at a reverse voltage of 18.2 V (75% of nominal 24 V Zener voltage). This value is specified in the Electrical Characteristics table of MSC0995.PDF under the "REVERSE CURRENT IR (MAX)" column for part number 1PMT5934B (the base variant of 1PMT5934CE3/TR13), and applies identically to the CE3 version.
Is 1PMT5934CE3/TR13 compatible with automated SMT assembly processes?
Yes, the 1PMT5934CE3/TR13 is fully compatible with automated insertion equipment. Its Powermite® package features a unique locking tab and full metallic bottom that prevent rotation and flux entrapment during reflow. It is supplied in EIA-481-compliant tape-and-reel format (TR13 = 13-inch reel, 12,000 pieces), and its mechanical design supports high-throughput pick-and-place and reflow profiling per IPC-J-STD-020.
What does the "E3" in 1PMT5934CE3/TR13 signify?
The "E3" in 1PMT5934CE3/TR13 denotes Microsemi's internal packaging and environmental compliance code. Per Microsemi documentation, "E3" indicates lead-free (Pb-free), RoHS-compliant termination finish and packaging per JEDEC J-STD-020 moisture sensitivity level (MSL) 1. It does not affect electrical specifications-1PMT5934CE3/TR13 retains identical Zener voltage, power rating, and thermal characteristics as non-E3 variants.
