Product details
Overview
1PMT5930AE3/TR7 from Microsemi is a 16 V, ±5% tolerance Zener diode in Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 10 Ω dynamic impedance at 23.4 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5930AE3/TR7 datasheet, 1PMT5930AE3/TR7 pinout, 1PMT5930AE3/TR7 application, or 1PMT5930AE3/TR7 equivalent, key selection criteria include Zener voltage tolerance, power derating above 60°C, reverse leakage at 12.2 V, knee current behavior, and compatibility with EIA-481 tape-and-reel automated placement.
Technical Context
This Zener diode operates in reverse breakdown mode with specified regulation at IZT = 23.4 mA and VZ = 16.0 V ±5%. Its Powermite® package features a full metallic bottom (TAB 1) acting as both cathode terminal and primary heat path, enabling 3.0 W dissipation when TAB 1 is held at ≤60°C.
Electrical performance is characterized at TL = 30°C with strict measurement timing (20 s after DC current application). Dynamic impedance (ZZT = 10 Ω) and knee impedance (ZZK = 0.25 Ω) are defined per Microsemi Note 202, supporting stable regulation across load transients in low-noise analog and power management circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 16.0 V ±5% at IZT = 23.4 mA - defines nominal regulation point with tight production control for feedback loop accuracy |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power handling with mandatory thermal management at PCB level |
| Dynamic Impedance | 10 Ω at IZT - determines output voltage deviation under small-signal AC load variations |
| Knee Current | 0.25 mA at VR = 12.2 V - specifies minimum current to achieve stable regulation onset, critical for low-power standby modes |
| Reverse Leakage | ≤1 µA at VR = 12.2 V - ensures minimal quiescent current in clamping or reference applications |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt, guiding copper pour and thermal via design on PCB |
| ESD Rating | >16 kV HBM - provides robustness against handling and board-level electrostatic discharge events |
Pinout & Package
The 1PMT5930AE3/TR7 uses a DO-216 molded surface-mount package with two terminals: TAB 1 (cathode, full metallic bottom) and the opposite molded lead (anode). Mounting orientation is unrestricted; TAB 1 serves as both electrical cathode and primary thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat sink and return path for Zener current; must be soldered to ≥1 cm² copper area for rated 3.0 W operation |
| Lead (opposite TAB) | Anode | Input terminal for reverse-bias connection; no thermal function - minimal copper required |
Key Features
| Feature | Design Value |
|---|---|
| Powermite® full metallic bottom | Eliminates solder flux entrapment during reflow, ensuring reliable void-free solder joints and consistent thermal transfer |
| Integral heat sink locking tab | Provides mechanical retention during automated insertion and enhances thermal conduction from junction to PCB |
| ESD robustness | >16 kV HBM rating enables direct handling and assembly without special ESD controls beyond standard practices |
| Tight voltage tolerance option | Available in ±2% (suffix C) and ±1% (suffix D) - supports high-accuracy references where 16 V stability is critical |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | 14 V nominal, 1 W rating, DO-41 through-hole package, 22 Ω ZZT | Limited to lower-power, non-SMT designs; unsuitable for 3 W clamping or automated SMT lines | Select only if legacy through-hole assembly or sub-1 W regulation is required |
| BZX84-C16 | 16 V nominal, 300 mW rating, SOT-23 package, 40 Ω ZZT, 100 nA IR | Lower power handling and higher impedance limit use to signal-level references, not power rail clamping | Prefer for space-constrained low-current biasing where 3 W capability is unnecessary |

FAQ
What is the Zener voltage tolerance for 1PMT5930AE3/TR7?
The 1PMT5930AE3/TR7 has a standard Zener voltage tolerance of ±5% at 16.0 V, measured at IZT = 23.4 mA with TAB 1 held at 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available as alternate orderables, but the base 1PMT5930AE3/TR7 part carries the ±5% specification confirmed in MSC0995 Rev F.
How much power can 1PMT5930AE3/TR7 dissipate continuously?
The 1PMT5930AE3/TR7 is rated for 3.0 W DC power dissipation when TAB 1 is maintained at ≤60°C. This requires adequate PCB copper area and thermal vias. Derating is necessary above 60°C - for example, at TAB 1 = 100°C, maximum dissipation drops to approximately 1.8 W per the 30°C/W thermal resistance specification.
Is 1PMT5930AE3/TR7 compatible with automated SMT assembly?
Yes, the 1PMT5930AE3/TR7 is fully compatible with automated insertion equipment. Its Powermite® package includes a unique locking tab and full metallic bottom designed specifically for reliable pick-and-place and reflow soldering. It ships in EIA-481 tape-and-reel format (3,000 pcs per 7-inch reel), meeting industry-standard SMT handling requirements.
What is the reverse leakage current specification for 1PMT5930AE3/TR7?
The reverse leakage current (IR) for 1PMT5930AE3/TR7 is guaranteed ≤1 µA at VR = 12.2 V and TL = 30°C. This low leakage supports stable operation in high-impedance reference and bias networks, minimizing error contribution in precision analog circuits using the 1PMT5930AE3/TR7.
Does 1PMT5930AE3/TR7 have an ESD rating, and what is it?
Yes, the 1PMT5930AE3/TR7 has an ESD rating of >16 kV per the Human Body Model (HBM), as stated in the MSC0995 datasheet. This high rating reflects robust internal structure and packaging, allowing safe handling and assembly in standard electronics manufacturing environments without requiring additional ESD mitigation beyond standard protocols.
