Product details
Overview
1PMT5933AE3/TR7 from Microsemi is a 22 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 dynamic impedance of 17.5 Ω at 17 mA test current and reverse leakage ≤1 µA at 16.7 V, used for precision voltage regulation in space-constrained DC-DC converter feedback loops.
For engineers reviewing the 1PMT5933AE3/TR7 datasheet, 1PMT5933AE3/TR7 pinout, 1PMT5933AE3/TR7 application, or 1PMT5933AE3/TR7 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 EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates as a two-terminal voltage reference device with cathode designated by TAB 1, requiring no external biasing circuitry. Its full metallic bottom and integral heat sink locking tab enable direct thermal conduction to the PCB pad, supporting stable regulation under transient load conditions.
The device exhibits tight voltage regulation across temperature (–55°C to +150°C junction/storage range) and maintains low reverse leakage (≤1 µA at VR = 16.7 V), with knee current IZK = 0.25 mA and knee impedance ZZK = 650 Ω - enabling reliable turn-on behavior in low-current bias networks.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5933B | DO-41 through-hole package; same 22 V ±5%, but higher thermal resistance (~65°C/W) and no metallic bottom | Requires manual or wave-solder assembly; unsuitable for high-density SMT layouts | Select 1N5933B only if legacy through-hole manufacturing or higher single-pulse surge capability is required |
| BZX84-C22 | SOT-23 package; 22 V ±5%, 300 mW rating, 80 Ω ZZT - significantly lower power and thermal performance | Limited to low-power signal-level clamping; cannot replace 1PMT5933AE3/TR7 in 3 W regulation roles | Choose BZX84-C22 only for space-constrained, sub-500 mW bias/reference use where thermal derating is acceptable |
Compared with 1N5933B and BZX84-C22, the 1PMT5933AE3/TR7 uniquely combines 3.0 W SMT power handling, 30°C/W thermal resistance, and EIA-481 tape-and-reel compatibility - making it the only viable choice for automated production of thermally demanding, high-reliability Zener regulation circuits.
