Product details
Overview
1PMT5933BE3/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 17.5 Ω dynamic impedance at 17 mA test current and thermal resistance of 30°C/W junction-to-TAB1 - used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the 1PMT5933BE3/TR13 datasheet, 1PMT5933BE3/TR13 pinout, 1PMT5933BE3/TR13 application, or 1PMT5933BE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, power derating above 60°C, reverse leakage at 16.7 V, knee current behavior at 0.25 mA, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, maintaining stable 22 V regulation across load variations when reverse-biased above its breakdown threshold. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and mechanical stability during reflow soldering.
Electrical performance is characterized at TL = 30°C with IZT = 17 mA; dynamic impedance (ZZT = 17.5 Ω) and knee impedance (ZZK = 650 Ω at IZK = 0.25 mA) define low-noise regulation capability and soft-breakdown onset - critical for low-power sensing and biasing circuits where leakage (IR ≤ 1 µA at VR = 16.7 V) must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 22 V ±5% at IZT = 17 mA - defines nominal regulation point with tight production control for stable reference generation |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-density board layouts without external heatsinking in moderate ambient conditions |
| Dynamic Impedance | 17.5 Ω at IZT - ensures minimal output voltage variation under changing load current in feedback or clamp applications |
| Knee Current | 0.25 mA - specifies lowest usable bias current before significant voltage deviation, supporting ultra-low-power standby regulation |
| Reverse Leakage | ≤1 µA at VR = 16.7 V - guarantees negligible quiescent current draw in battery-backed or energy-harvesting systems |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows accurate thermal modeling for PCB copper pour sizing and reliability prediction |
| ESD Rating | >16 kV HBM - provides robust handling margin during SMT assembly and field operation without additional protection |
Pinout & Package
The 1PMT5933BE3/TR13 uses the DO-216 surface-mount package (Powermite®), featuring a molded body with full metallic bottom and integral heat-sink locking tab. Cathode is designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat path and electrical cathode connection - must be soldered to thermal pad for rated 3.0 W dissipation |
| Lead 2 | Anode | Standard anode terminal - routed to ground or low-impedance return path in shunt regulator configuration |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling in footprint smaller than DO-41 or SOD-123 |
| Full metallic bottom | Eliminates solder flux entrapment risk and improves thermal transfer efficiency to PCB copper layers |
| Integral heat-sink locking tab | Provides mechanical anchoring during thermal cycling and enhances thermal conduction from junction to TAB 1 |
| ESD rating >16 kV HBM | Reduces need for external ESD protection in industrial I/O and automotive sensor interface designs |
| ±5% Zener tolerance (standard) | Meets cost-sensitive regulation requirements without requiring tighter-tolerance variants (C/D suffixes) |
Applications
| Industrial Power Supply Monitoring | Automotive Body Control Module (BCM) Clamping |
|---|---|

IC Role / Device Role / Timing Role: Primary ESD clamp on 3.3 V/5 V auxiliary supply lines feeding PHY ICs. Use Value: >16 kV HBM rating exceeds IEC standard; low leakage preserves rail integrity during idle states. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5933B | Same 22 V Zener voltage and ±5% tolerance, but in DO-41 through-hole package with higher thermal resistance (50°C/W) | Requires manual or wave-solder assembly; unsuitable for high-density SMT layouts | Select 1N5933B only if legacy through-hole design or prototyping with breadboard compatibility is required |
| BZX84-C22 | 22 V Zener in SOT-23 package, rated 300 mW, 10x lower power handling and no metallic thermal tab | Limited to low-power signal-level clamping; cannot replace 1PMT5933BE3/TR13 in 3 W power regulation roles | Choose BZX84-C22 only for space-constrained signal conditioning where power dissipation remains below 300 mW |
Compared with 1N5933B and BZX84-C22, the 1PMT5933BE3/TR13 uniquely combines SMT compatibility, 3.0 W power capability, and low thermal resistance via its Powermite® metallic-tab construction - making it irreplaceable in thermally demanding, high-reliability DC rail regulation.

FAQ
What is the Zener voltage tolerance of the 1PMT5933BE3/TR13?
The 1PMT5933BE3/TR13 has a standard Zener voltage tolerance of ±5% at 22 V, measured at IZT = 17 mA with TAB 1 temperature held at 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, respectively, but the base part number 1PMT5933BE3/TR13 ships with ±5% as specified in the MSC0995 datasheet.
How is thermal performance defined for the 1PMT5933BE3/TR13?
The 1PMT5933BE3/TR13 has a junction-to-TAB1 thermal resistance of 30°C/W, meaning each watt of dissipated power raises the junction temperature 30°C above the TAB 1 temperature. This value assumes full solder coverage of the metallic bottom to a thermally optimized PCB pad - critical for achieving the rated 3.0 W dissipation at TAB 1 = 60°C.
Can the 1PMT5933BE3/TR13 be used in place of a DO-41 Zener diode like the 1N5933B?
No - while the 1PMT5933BE3/TR13 and 1N5933B share identical electrical parameters (22 V, ±5%, 3.0 W), they differ fundamentally in package: 1PMT5933BE3/TR13 uses the surface-mount Powermite® (DO-216) package with metallic thermal tab, whereas 1N5933B is through-hole DO-41. Direct substitution requires PCB redesign and thermal validation due to different thermal paths and mounting methods.
What is the maximum reverse leakage current for the 1PMT5933BE3/TR13?
The maximum reverse leakage current for the 1PMT5933BE3/TR13 is 1 µA at VR = 16.7 V and TL = 30°C. This low leakage supports energy-efficient designs such as battery-powered sensors and always-on monitoring circuits where standby current must remain sub-microamp.
Is the 1PMT5933BE3/TR13 compatible with standard EIA-481 tape-and-reel equipment?
Yes - the 1PMT5933BE3/TR13 is supplied in EIA-481 compliant tape-and-reel packaging, with 3,000 pieces per 7-inch reel and 12,000 pieces per 13-inch reel. Its Powermite® package geometry and orientation are validated for reliable feeding and placement using industry-standard SMT pick-and-place machines.
