Product details
Overview
1PMT5933B/TR13 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 17 Ω dynamic impedance at 17 mA test current and 16.7 V minimum reverse voltage, used for precision voltage regulation in compact power supply rails.
For engineers reviewing the 1PMT5933B/TR13 datasheet, 1PMT5933B/TR13 pinout, 1PMT5933B/TR13 application, or 1PMT5933B/TR13 equivalent, key selection criteria include zener voltage accuracy, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low reverse leakage (≤1 µA at 16.7 V), and compatibility with automated SMT 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.
Designed for operation across -55°C to +150°C junction temperature range, it maintains specified zener voltage within tolerance when measured at 20 seconds after applying 17 mA DC test current at TAB temperature of 30°C, per Microsemi Note 202 for voltage-current deviation analysis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V ±5% - defines regulated output voltage level under nominal 17 mA test current |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous thermal load on PCB copper area |
| Dynamic Impedance (ZZT) | 17.5 Ω at IZT = 17 mA - determines output voltage variation under load current changes |
| Thermal Resistance | 30°C/W junction-to-TAB - quantifies temperature rise per watt dissipated into PCB pad |
| ESD Rating | >16 kV HBM - ensures robustness during handling and board assembly without external protection |
| Reverse Leakage | ≤1 µA at VR = 16.7 V - guarantees minimal standby current in voltage-clamp or reference applications |
| Knee Current (IZK) | 0.25 mA - minimum current required to enter stable zener breakdown region |
Pinout & Package
The 1PMT5933B/TR13 uses a DO-216 molded surface-mount package with full metallic bottom and integral heat sink locking tab. Cathode is designated by TAB 1; anode is the opposite terminal. Mounting orientation is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat path and voltage reference node; must be connected to ground or low-impedance return plane |
| Opposite Terminal | Anode | Input/positive rail connection point; reverse-biased during regulation |
Key Features

FAQ
What is the zener voltage tolerance for 1PMT5933B/TR13?
The 1PMT5933B/TR13 has a standard zener voltage tolerance of ±5% at 22 V, measured at 17 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, respectively, but the base part number 1PMT5933B/TR13 specifies ±5%.
How is thermal performance characterized for 1PMT5933B/TR13?
The 1PMT5933B/TR13 features a thermal resistance of 30°C/W from junction to TAB 1, enabling efficient heat transfer to the PCB copper pad. This value assumes proper mounting on a minimum 100 mm² copper area and is critical for sustaining its 3.0 W power rating at TAB temperatures up to 60°C.
Does 1PMT5933B/TR13 require external ESD protection?
No, the 1PMT5933B/TR13 does not require external ESD protection due to its >16 kV rating per the Human Body Model. This built-in robustness simplifies board design and eliminates the need for additional TVS components in most handling and operational environments.
What is the maximum reverse leakage current for 1PMT5933B/TR13?
The maximum reverse leakage current for 1PMT5933B/TR13 is 1 µA at a reverse voltage of 16.7 V, measured at 30°C. This low leakage supports precision voltage reference and low-power biasing applications where standby current must be minimized.
Can 1PMT5933B/TR13 be used in automatic insertion equipment?
Yes, the 1PMT5933B/TR13 is explicitly designed for compatibility with automatic insertion equipment. Its Powermite® package includes a unique locking tab and full metallic bottom that ensure reliable pick-and-place placement and prevent solder flux entrapment during reflow assembly.
