Product details
Overview
1PMT5933CE3/TR13 from Microsemi is a 22 V, ±5% tolerance Zener diode in Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 17.5 Ω dynamic impedance at 17 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in power supply regulation and ESD protection circuits.
For engineers reviewing the 1PMT5933CE3/TR13 datasheet, 1PMT5933CE3/TR13 pinout, 1PMT5933CE3/TR13 application, or 1PMT5933CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance (±5%), 3.0 W power handling with metallic-tab thermal path, ESD rating >16 kV HBM, low reverse leakage (≤1 µA at 16.7 V), and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This device operates as a silicon planar Zener diode with sharp knee characteristics, designed for stable voltage regulation under DC bias conditions. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and eliminate solder flux entrapment during reflow.
The 1PMT5933CE3/TR13 exhibits a nominal Zener voltage of 22 V measured at 17 mA (IZT), with 17.5 Ω dynamic impedance (ZZT) and 650 Ω knee impedance (ZZK) at 0.25 mA (IZK). Reverse leakage remains ≤1 µA up to 16.7 V, supporting low-power standby regulation and precision clamping.
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 |
|---|---|---|---|
| SMCJ22A | TVS diode (not Zener); 22 V standoff, 300 W peak pulse power, unidirectional | Designed for transient suppression only; lacks precision DC regulation capability | Select when primary need is surge immunity, not stable DC reference |
| BZX84-C22 | SOT-23 Zener; 22 V ±5%, 300 mW power, 50 Ω dynamic impedance, no metallic thermal tab | Limited to low-power biasing; unsuitable for >500 mW continuous dissipation | Select for cost-sensitive, low-current applications where thermal performance is secondary |
Compared with SMCJ22A and BZX84-C22, the 1PMT5933CE3/TR13 uniquely combines 3.0 W DC power handling, metallic-tab thermal conduction, and precision Zener regulation-making it suitable for hybrid roles requiring both steady-state reference accuracy and moderate transient absorption.

FAQ
What is the Zener voltage tolerance for 1PMT5933CE3/TR13?
The 1PMT5933CE3/TR13 has a standard Zener voltage tolerance of ±5% at 22 V, measured at 17 mA test current and TAB 1 temperature of 30°C. This tolerance is confirmed in Microsemi's MSC0995 datasheet revision F, and applies to the "E3" suffix variant. Tighter tolerances (±2%, ±1%) are available with "C" and "D" suffixes, respectively.
How is thermal performance defined for 1PMT5933CE3/TR13?
The 1PMT5933CE3/TR13 specifies a thermal resistance of 30°C/W junction-to-TAB1, meaning each watt of dissipated power raises the junction temperature by 30°C above the TAB 1 temperature. Full 3.0 W operation requires TAB 1 to be held at ≤60°C, as stated in the Maximum Ratings table of the MSC0995 datasheet.
Is 1PMT5933CE3/TR13 compatible with automated SMT assembly?
Yes, the 1PMT5933CE3/TR13 is supplied in EIA-481-compliant tape-and-reel format (7-inch reel, 3,000 pieces), and its Powermite® package features a unique locking tab and full metallic bottom optimized for reliable pickup, placement, and reflow soldering using standard SMT equipment.
What is the maximum reverse leakage current for 1PMT5933CE3/TR13?
The maximum reverse leakage current for 1PMT5933CE3/TR13 is 1 µA at a reverse voltage of 16.7 V, as specified in the Electrical Characteristics table of the MSC0995 datasheet. This value is measured at TL = 30°C and confirms suitability for low-quiescent-current applications such as battery-powered sensors.
Does 1PMT5933CE3/TR13 have ESD protection built-in?
Yes, the 1PMT5933CE3/TR13 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), as documented in the FEATURES section of the MSC0995 datasheet. This intrinsic robustness reduces or eliminates the need for additional external ESD protection components in many interface circuits.
