Product details
Overview
1PMT5930E3/TR7 from Microsemi is a 16 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 10 Ω dynamic impedance at 23.4 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 1PMT5930E3/TR7 datasheet, 1PMT5930E3/TR7 pinout, 1PMT5930E3/TR7 application, or 1PMT5930E3/TR7 equivalent, key selection criteria include zener voltage tolerance, power derating above 60°C, reverse leakage at 12.2 V, knee current (0.25 mA), and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its Powermite® package integrates a full metallic bottom and locking tab that serves as both mechanical anchor and thermal path to PCB copper, enabling efficient heat transfer without flux entrapment.
Electrical behavior is defined by tight parameter control: zener voltage measured at 23.4 mA (IZT), dynamic impedance specified at 10% AC superimposed on IZT, and reverse leakage capped at 1 µA max at VR = 12.2 V - all validated at TL = 30°C with 20-second stabilization time post-current application.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16.0 V ±5% at IZT = 23.4 mA, TL = 30°C - defines nominal regulation point with predictable deviation across production lot. |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum steady-state power handling before thermal derating applies. |
| Dynamic Impedance (ZZT) | 10 Ω at IZT = 23.4 mA - determines output voltage variation under small-signal load transients. |
| Knee Current (IZK) | 0.25 mA - minimum current needed to enter usable regulation region; critical for low-power biasing. |
| Reverse Leakage (IR) | ≤1 µA at VR = 12.2 V - ensures minimal standby current in clamping or reference circuits. |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies thermal path efficiency; requires adequate PCB copper area under TAB 1 for safe operation. |
| ESD Rating | >16 kV HBM - supports robust handling during SMT assembly and field operation without added protection. |
Pinout & Package
The 1PMT5930E3/TR7 uses a DO-216–compatible Powermite® surface-mount package with molded body and full metallic bottom. Cathode is designated by TAB 1; mounting orientation is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat sink interface and electrical cathode connection; must be soldered to thermally conductive PCB pad. |
| Lead 2 | Anode | Standard anode terminal; electrically isolated from TAB 1; connects to system ground or return path. |
Key Features
| Feature | Design Value |
|---|---|
| Integral heat sink locking tab | Mechanically anchors device during reflow and conducts heat directly from junction to PCB via TAB 1. |
| Full metallic bottom | Eliminates solder flux entrapment risk, improving long-term reliability and solder joint integrity. |
| ESD robustness | >16 kV per Human Body Model - reduces need for external ESD protection in end equipment. |
| Automated insertion compatibility | Designed for pick-and-place and reflow processes per EIA-481 tape-and-reel standard (7″/3,000 pcs). |
Applications
| Industrial Power Supply Regulation | Automotive ECUs |
|---|---|
Use Scenario: Stabilizing 15–17 V auxiliary rails in programmable logic controllers and motor drive control boards. IC Role / Device Role / Timing Role: Precision shunt voltage reference and overvoltage clamp protecting downstream regulators and microcontrollers.

IC Role / Device Role / Timing Role: Low-noise, low-leakage voltage reference ensuring signal integrity in high-gain analog chains. Use Value: ≤1 µA reverse leakage at 12.2 V prevents input offset errors; ±5% VZ tolerance meets Class II medical accuracy requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5930B | Same 16 V zener voltage and ±5% tolerance, but in DO-41 through-hole package; no integral heat sink tab; 1.2 W power rating. | Requires manual or wave soldering; unsuitable for high-density SMT layouts or thermal-critical designs. | Select 1N5930B only when board space allows through-hole placement and power demand stays below 1.2 W. |
| BZX84-C16 | 16 V SOT-23 Zener; 300 mW rating; 30 Ω typical ZZT; 100 nA IR at 12.2 V - lower leakage but significantly lower power and thermal capability. | Used in low-power signal conditioning, not power rail regulation; lacks metallic thermal path. | Choose BZX84-C16 for battery-powered sensors where leakage dominates over power handling. |
Compared with 1N5930B and BZX84-C16, the 1PMT5930E3/TR7 uniquely delivers 3.0 W power handling in a surface-mount form with direct thermal coupling to PCB - making it the only option among the three suitable for regulated 16 V rails dissipating >1 W continuously.

FAQ
What is the zener voltage tolerance of the 1PMT5930E3/TR7?
The 1PMT5930E3/TR7 has a standard zener voltage tolerance of ±5% at 16.0 V, measured at IZT = 23.4 mA and TL = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the E3/TR7 variant specifies ±5%. This tolerance remains valid across the full operating junction temperature range of -55°C to +150°C.
How much power can the 1PMT5930E3/TR7 safely dissipate?
The 1PMT5930E3/TR7 is rated for 3.0 W DC power dissipation when TAB 1 is maintained at 60°C. Power must be linearly derated above 60°C at 40 mW/°C, reaching zero at 135°C. Safe operation requires a thermally robust PCB layout with sufficient copper area under TAB 1 to sustain the required thermal resistance of 30°C/W junction-to-TAB1.
Is the 1PMT5930E3/TR7 compatible with automated SMT assembly?
Yes, the 1PMT5930E3/TR7 is fully compatible with automated SMT assembly. It ships in EIA-481 compliant tape-and-reel format (7″ reel, 3,000 pieces), features a locking tab for secure placement during pick-and-place, and its full metallic bottom eliminates solder flux entrapment - ensuring reliable reflow solder joints without post-assembly cleaning.
What is the reverse leakage current specification for the 1PMT5930E3/TR7?
The reverse leakage current (IR) of the 1PMT5930E3/TR7 is guaranteed ≤1 µA at VR = 12.2 V and TL = 30°C. This low leakage supports stable biasing in high-impedance reference circuits and minimizes quiescent current in always-on protection schemes - critical for battery-backed or energy-efficient systems.
Does the 1PMT5930E3/TR7 have ESD protection built-in?
Yes, the 1PMT5930E3/TR7 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), as verified per JEDEC JS-001. This intrinsic robustness eliminates the need for external ESD protection components in most end-equipment interfaces, simplifying design and improving reliability in environments prone to handling or operational electrostatic discharge.
