Product details
Overview
1PMT5930CE3/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 in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the 1PMT5930CE3/TR7 datasheet, 1PMT5930CE3/TR7 pinout, 1PMT5930CE3/TR7 application, or 1PMT5930CE3/TR7 equivalent, key selection criteria include zener voltage tolerance (±5%), low reverse leakage (<1 µA at 12.2 V), ESD rating (>16 kV HBM), thermal performance (30°C/W), and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, leveraging silicon PN junction breakdown to maintain stable reverse-bias voltage across its cathode (TAB 1) and anode terminals. Its design targets regulated DC output stages where tight voltage control and thermal stability are required under varying load and temperature conditions.
The 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 solder flux entrapment. Junction-to-TAB1 thermal resistance is specified at 30°C/W, supporting sustained 3.0 W dissipation when TAB 1 is held at ≤60°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 16 V ±5% at IZT = 23.4 mA - defines nominal regulation point with predictable deviation in production units. |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous DC power handling with defined thermal boundary condition. |
| Dynamic Impedance ZZT | 10 Ω at IZT = 23.4 mA - indicates small-signal AC resistance affecting regulation accuracy under varying current. |
| Reverse Leakage IR | <1 µA at VR = 12.2 V - ensures minimal standby current in high-impedance bias networks. |
| Thermal Resistance θJT | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt dissipated, critical for thermal design margining. |
| ESD Rating | >16 kV per Human Body Model - supports robustness during handling and board assembly without external protection. |
| Forward Voltage VF | 1.2 V at IF = 200 mA - relevant for reverse-polarity protection or series-switch applications. |
Pinout & Package
Package: Powermite® (DO-216AA), molded surface-mount package with full metallic bottom and integral locking tab; cathode designated by TAB 1; mounting position unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat sink interface and electrical cathode connection; must be soldered to thermal pad for rated power handling. |
| Lead 2 | Anode | Standard anode terminal; electrically isolated from TAB 1; connects to regulated node or ground return path. |
Key Features
| Feature | Design Value |
|---|---|
| Integral heat sink locking tab | Mechanically anchors device during reflow while conducting heat directly from junction to PCB copper via TAB 1. |
| Full metallic bottom | Eliminates solder flux entrapment risk during SMT assembly, improving long-term reliability and void-free solder joints. |
| ESD robustness | Exceeds 16 kV HBM - reduces need for external ESD protection in board-level transient environments. |
| Automated insertion compatibility | Designed for pick-and-place and reflow processes per EIA-481 tape-and-reel standards (7″/3,000 pcs, 13″/12,000 pcs). |
Applications

Use Value: 30°C/W θJT allows thermal tracking with adjacent power components; DO-216 footprint fits compact layout constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5930BTR | Same 16 V ±5%, but in DO-41 through-hole package; no metallic thermal tab; θJA ≈ 65°C/W vs. 30°C/W. | Limited to lower-power or non-SMT designs; unsuitable for high-density or thermally constrained layouts. | Select only if through-hole assembly is mandated and thermal budget permits higher junction temperature rise. |
| BZX55C16-TR | 16 V ±5%, DO-35 package; 500 mW rating; 35 Ω ZZT; no specified ESD rating. | Restricted to signal-level or low-power biasing; cannot replace 3.0 W regulation or clamping roles. | Use only in low-current reference paths where power and thermal demands are negligible. |

FAQ
What is the Zener voltage tolerance for 1PMT5930CE3/TR7?
The 1PMT5930CE3/TR7 has a standard Zener voltage tolerance of ±5% at 16 V, measured at 23.4 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, respectively, but the CE3/TR7 variant specifies ±5%.
How is thermal performance defined for 1PMT5930CE3/TR7?
Thermal performance of the 1PMT5930CE3/TR7 is defined by a junction-to-TAB1 thermal resistance of 30°C/W. This means the silicon junction rises 30°C above TAB 1 temperature for every watt dissipated - critical for designing PCB copper area and airflow to maintain ≤60°C TAB temperature under 3.0 W operation.
Is 1PMT5930CE3/TR7 compatible with automated SMT assembly?
Yes, the 1PMT5930CE3/TR7 is fully compatible with automated SMT assembly. It ships in EIA-481 compliant tape-and-reel packaging (7″ reel, 3,000 pieces), and its Powermite® package features a locking tab and full metallic bottom designed specifically for reliable pick-and-place and reflow soldering without flux entrapment.
What is the maximum reverse leakage current for 1PMT5930CE3/TR7?
The maximum reverse leakage current for 1PMT5930CE3/TR7 is 1 µA at a reverse voltage of 12.2 V, measured at 30°C. This low leakage supports high-impedance bias networks and precision reference applications where standby current must be minimized.
Does 1PMT5930CE3/TR7 have ESD protection built-in?
Yes, the 1PMT5930CE3/TR7 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), as confirmed in the official Microsemi datasheet. This intrinsic robustness eliminates the need for additional external ESD protection in most board-level implementations.
