Product details
Overview
1PMT5930B from Microsemi is a 16 V, 3.0 W surface-mount Zener diode in the Powermite® package, featuring 10 Ω dynamic impedance at 23.4 mA test current, 12.2 mA maximum Zener current, and thermal resistance of 30°C/W junction-to-tab. It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5930B datasheet, 1PMT5930B pinout, 1PMT5930B application, or 1PMT5930B equivalent, key selection criteria include its 16 V nominal Zener voltage with ±5% tolerance, 3.0 W power rating at TAB 1 = 60°C, low reverse leakage (≤1 µA at 12.2 V), ESD robustness (>16 kV HBM), and DO-216 mechanical outline compatibility.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations and temperature shifts. Its Powermite® package integrates a full metallic bottom for flux-free soldering and a locking tab that functions as both mechanical anchor and thermal path to PCB copper.
The device exhibits tight knee characteristics (IZK = 0.25 mA, ZZK = 600 Ω) and low dynamic impedance (ZZT = 10 Ω), enabling accurate regulation under moderate current transients. Junction-to-tab thermal resistance of 30°C/W supports reliable operation up to +150°C junction temperature when mounted on adequate copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V ±5% at IZT = 23.4 mA - defines stable regulation point for feedback or clamping circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power handling with thermal derating above 60°C |
| Dynamic Impedance (ZZT) | 10 Ω at 23.4 mA - determines output voltage variation under load current changes |
| Max Zener Current (IZM) | 12.2 mA - derived from 3.0 W / 16 V; limits safe DC operating current without exceeding power rating |
| Reverse Leakage (IR) | ≤1 µA at VR = 12.2 V - ensures minimal quiescent current in high-impedance bias or sensing nodes |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt; requires ≥1 cm² copper pad for full 3.0 W rating |
| ESD Rating | >16 kV per Human Body Model - enables robust handling during automated assembly and field operation |
Pinout & Package
Package: Powermite® (DO-216AA), molded surface-mount case with full metallic bottom and integral heat-sink locking tab. Cathode designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal; must be connected to PCB copper pour for thermal management and electrical reference |
| Lead 2 | Anode | Signal-side connection; routed to ground or low-impedance return path in shunt regulation configurations |
Key Features
| Feature | Design Value |
|---|---|
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and void-free solder joints |
| Integral heat-sink locking tab | Provides mechanical retention during automated insertion and enhances thermal conduction to PCB |
| Low knee impedance (ZZK = 600 Ω) | Enables stable regulation even at low bias currents (IZK = 0.25 mA), suitable for low-power standby circuits |
| ESD robustness >16 kV HBM | Reduces need for external protection in board-level ESD-prone environments such as industrial I/O modules |
Applications
| Industrial Power Supply Feedback | Automotive Body Control Module Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF16A (ON Semiconductor) | Same 16 V nominal voltage, but 1.0 W rating and SOD-123 package; higher ZZT (25 Ω) | Suitable only for low-power signal clamping, not 3.0 W rail regulation | Select 1PMT5930B when >1.5 W continuous dissipation or DO-216 footprint is required |
| BZX84-C16 (Diodes Inc.) | 16 V ±5%, 300 mW rating, SOT-23 package; no metallic thermal tab | Limited to bias/reference use; cannot replace 1PMT5930B in power-clamp roles | Choose 1PMT5930B where thermal performance, ESD immunity, or mechanical robustness in automated assembly is critical |
Compared with SMF16A and BZX84-C16, the 1PMT5930B delivers three times the power handling, integrated thermal path via TAB 1, and superior ESD resilience-making it uniquely suited for industrial and automotive power-rail stabilization where reliability under thermal and electrical stress is non-negotiable.

FAQ
What is the Zener voltage tolerance for 1PMT5930B?
The 1PMT5930B has a standard Zener voltage tolerance of ±5% at 16 V nominal, measured at 23.4 mA test current and TAB 1 temperature of 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request. This tolerance directly impacts regulation accuracy in feedback loops and clamping thresholds in protection circuits.
Can 1PMT5930B be used in place of through-hole Zener diodes like 1N5245B?
No-1PMT5930B is not a direct replacement for 1N5245B due to fundamental differences in package, thermal path, and power derating. While both are 16 V Zeners, 1PMT5930B uses the DO-216 Powermite® package with metallic tab for PCB heat sinking, whereas 1N5245B is DO-35 glass with axial leads. Layout and thermal design must be re-validated when substituting 1PMT5930B.
What is the maximum allowable junction temperature for 1PMT5930B?
The maximum junction temperature for 1PMT5930B is +150°C, with storage temperature range also specified from –55°C to +150°C. Operation at this limit requires sufficient PCB copper area to maintain TAB 1 ≤60°C, as the 3.0 W rating is defined at that tab temperature. Exceeding +150°C risks permanent parametric shift or catastrophic failure.
How does the Powermite® package improve manufacturability compared to standard SMD Zeners?
The Powermite® package improves manufacturability via its full metallic bottom (preventing solder flux entrapment) and integral locking tab (ensuring secure placement during pick-and-place). These features reduce post-reflow defects like voids or tombstoning, increase first-pass yield in high-volume automated assembly, and eliminate manual rework associated with conventional plastic SMD packages.
Is 1PMT5930B suitable for bidirectional transient voltage suppression?
No-1PMT5930B is a unidirectional Zener diode optimized for reverse-biased voltage regulation and clamping. It lacks symmetrical breakdown characteristics required for bidirectional TVS applications. For bidirectional surge protection, dedicated TVS diodes such as SMAJ16A or SMCJ16A should be selected instead of 1PMT5930B.
