Product details
Overview
1PMT5933C/TR13 from Microsemi is a 22 V, ±1% tolerance surface-mount Zener diode in the Powermite® 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-tab. It serves as a precision voltage reference or overvoltage clamp in power supply regulation and ESD-protected signal lines.
For engineers reviewing the 1PMT5933C/TR13 datasheet, 1PMT5933C/TR13 pinout, 1PMT5933C/TR13 application, or 1PMT5933C/TR13 equivalent, key selection criteria include zener voltage tolerance (±1%), low knee impedance (650 Ω at 0.25 mA), ESD rating (>16 kV HBM), reverse leakage (≤1 µA at 16.7 V), and thermal performance in high-density SMT layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range (IZT = 17 mA). Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and eliminate solder flux entrapment during reflow assembly.
The device exhibits low reverse leakage (≤1 µA at VR = 16.7 V), stable dynamic impedance (17.5 Ω at IZT), and a defined knee region (IZK = 0.25 mA, ZZK = 650 Ω), enabling reliable operation in low-current biasing and precision clamping applications where voltage stability under varying load conditions is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V ±1% at IZT = 17 mA - ensures tight regulation for reference or feedback circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - supports robust thermal management in compact SMT designs |
| Dynamic Impedance (ZZT) | 17.5 Ω at IZT = 17 mA - minimizes output voltage variation under load transients |
| Knee Impedance (ZZK) | 650 Ω at IZK = 0.25 mA - defines stable low-current regulation threshold |
| Reverse Leakage (IR) | ≤1 µA at VR = 16.7 V - reduces standby power loss in clamping configurations |
| ESD Rating | >16 kV per Human Body Model - provides inherent protection for I/O and interface lines |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - enables direct thermal path to PCB copper or heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5355B | Same 22 V nominal, ±5% tolerance (no C-suffix option); DO-204AL package; higher thermal resistance (50°C/W) | Lacks ±1% tolerance and integrated heat sink; less suitable for precision reference or high-power SMT layouts | Select when cost sensitivity outweighs accuracy and thermal performance requirements |
| BZX84-C22 | 22 V ±5%, SOT-23 package; 300 mW rating; no metallic tab; 600°C/W thermal resistance | Not rated for 3 W operation; unsuitable for power regulation or high-energy clamping | Choose only for low-power signal-level clamping where board space is constrained and power dissipation <300 mW |
Compared with 1N5355B and BZX84-C22, the 1PMT5933C/TR13 delivers superior voltage accuracy (±1% vs ±5%), higher power capability (3.0 W vs 5 W max but with better thermal path), and integrated thermal management-making it uniquely suited for industrial-grade SMT voltage references requiring long-term stability and ESD resilience.

What is the zener voltage tolerance for 1PMT5933C/TR13?
The "C" suffix in 1PMT5933C/TR13 denotes ±1% zener voltage tolerance at 22 V nominal, verified at IZT = 17 mA and TAB 1 temperature of 30°C. This tighter tolerance enables use in precision voltage references without external calibration, distinguishing it from standard ±5% variants like 1PMT5933B/TR13.
How is thermal performance characterized for 1PMT5933C/TR13?
The 1PMT5933C/TR13 has a junction-to-TAB 1 thermal resistance of 30°C/W, measured under DC conditions with TAB 1 held at 60°C. Its Powermite® package uses a full metallic bottom and locking tab to ensure efficient heat transfer to the PCB, supporting continuous 3.0 W dissipation when properly mounted to adequate copper area.
Does 1PMT5933C/TR13 meet industry ESD standards?
Yes, the 1PMT5933C/TR13 is rated for >16 kV per Human Body Model (HBM), as confirmed in the MSC0995 datasheet. This high ESD immunity allows direct integration into unprotected I/O paths-such as RS-485, CAN, or sensor interfaces-without requiring additional transient voltage suppressors in many industrial applications.
What is the maximum reverse leakage current for 1PMT5933C/TR13?
The maximum reverse leakage current for 1PMT5933C/TR13 is 1 µA at a reverse voltage of 16.7 V (76% of nominal VZ), tested at TL = 30°C. This low leakage supports energy-efficient operation in battery-powered sensor nodes and maintains signal integrity in high-impedance bias networks.
Is 1PMT5933C/TR13 compatible with standard SMT reflow profiles?
Yes, the 1PMT5933C/TR13 is qualified for standard lead-free reflow processes per J-STD-020. Its Powermite® package is designed for compatibility with automatic insertion and reflow equipment, and its full metallic bottom prevents solder flux entrapment-reducing voiding risk and improving long-term solder joint reliability.
