Product details
Overview
1PMT5930/TR7 from Microsemi is a 16 V, 3.0 W surface-mount Zener diode in the Powermite® package (DO-216), featuring 10 Ω dynamic impedance at 23.4 mA test current, 12.2 mA maximum Zener current, and ESD rating >16 kV HBM - used for precision voltage regulation and overvoltage protection in DC power rails.
For engineers reviewing the 1PMT5930/TR7 datasheet, 1PMT5930/TR7 pinout, 1PMT5930/TR7 application, or 1PMT5930/TR7 equivalent, key selection factors include its 16 V nominal Zener voltage with ±5% tolerance, 30°C/W junction-to-tab thermal resistance, full metallic bottom for flux-free soldering, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates as a two-terminal voltage reference and clamp device, with cathode designated by TAB 1 and designed for mounting in any orientation. Its Powermite® package integrates a locking tab that functions as both mechanical anchor and thermal path to PCB copper.
Electrical behavior is defined at TL = 30°C with IZT = 23.4 mA; Zener voltage drift versus current deviation follows Microsemi Note 202, and dynamic impedance (ZZT = 10 Ω) is measured using 60 Hz RMS AC superimposed at 10% of IZT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V ±5% at IZT = 23.4 mA - sets precise clamping threshold for 15–17 V rail protection |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-power regulation without external heatsink |
| Dynamic Impedance | 10 Ω at IZT - ensures stable output voltage under load transients |
| Junction-to-Tab Thermal Resistance | 30°C/W - allows direct thermal coupling to PCB copper pour via TAB 1 |
| ESD Rating | >16 kV per Human Body Model - supports robust handling in automated SMT lines |
| Reverse Leakage | ≤1 µA at VR = 12.2 V - guarantees low standby power loss in always-on circuits |
| Knee Current (IZK) | 0.25 mA - defines minimum current for reliable Zener conduction onset |

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) | 16 V, 1.0 W, SOD-123 package, 30 Ω ZZT, no metallic bottom | Limited to lower-power clamping; lacks integrated thermal tab and flux-free bottom | Select when cost or footprint is prioritized over thermal performance and ESD robustness |
| BZX84-C16 (Diodes Inc.) | 16 V, 300 mW, SOT-23, 40 Ω ZZT, 100 nA IR at 12.2 V | Not suitable for 3 W continuous dissipation; intended for signal-level referencing only | Choose only for low-current biasing where power handling is irrelevant |
Compared with SMF16A and BZX84-C16, the 1PMT5930/TR7 delivers 3× higher power capability, 3× lower dynamic impedance, and direct thermal path via TAB 1 - making it uniquely suited for industrial and automotive power-rail protection where sustained energy absorption and thermal stability are critical.

FAQ
What is the Zener voltage tolerance for 1PMT5930/TR7?
The 1PMT5930/TR7 has a standard Zener voltage tolerance of ±5% at 16 V, measured at IZT = 23.4 mA and TAB 1 temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the /TR7 variant uses the standard ±5% grade.
How is thermal management handled for 1PMT5930/TR7 in PCB layout?
Thermal management for 1PMT5930/TR7 relies on soldering TAB 1 directly to a copper pour, leveraging its 30°C/W junction-to-tab thermal resistance. The full metallic bottom ensures efficient heat transfer, and the locking tab provides mechanical stability - no additional heatsink is required for 3.0 W operation at TAB 1 ≤ 60°C.
Is 1PMT5930/TR7 compatible with lead-free reflow processes?
Yes, 1PMT5930/TR7 is qualified for lead-free reflow per J-STD-020. Its Powermite® package withstands peak temperatures up to 260°C, and the full metallic bottom prevents flux entrapment - ensuring reliable solder joint formation in modern Pb-free assembly lines.
What does the "/TR7" suffix indicate in 1PMT5930/TR7?
The "/TR7" suffix denotes tape-and-reel packaging per EIA-481 standard, with 3,000 units per 7-inch reel. This format is optimized for high-speed automated placement equipment and ensures consistent orientation (cathode at TAB 1) throughout the reel.
Can 1PMT5930/TR7 replace through-hole Zener diodes like 1N5245B?
No - 1PMT5930/TR7 is not a drop-in replacement for 1N5245B (16 V, 500 mW, DO-35). It offers 6× higher power (3.0 W vs. 0.5 W) and different thermal design (TAB 1 conduction vs. lead conduction). PCB layout, thermal pad, and current-limiting resistor values must be redesigned to use 1PMT5930/TR7 effectively.
