Product details
Overview
1PMT5928CE3/TR7 from Microsemi is a 13 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 7.0 Ω dynamic impedance at 28.8 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in power supply regulation circuits.
For engineers reviewing the 1PMT5928CE3/TR7 datasheet, 1PMT5928CE3/TR7 pinout, 1PMT5928CE3/TR7 application, or 1PMT5928CE3/TR7 equivalent, key selection criteria include zener voltage tolerance (±5%), ESD rating (>16 kV HBM), low reverse leakage (1 µA max at 10.4 V), compatibility with automated insertion, and full metallic bottom for flux-free soldering.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and line conditions. Its Powermite® package integrates a locking tab acting as an integral heat sink and features a full metallic bottom to prevent solder flux entrapment during reflow assembly.
Rated for -55°C to +150°C junction and storage temperature, it delivers 3.0 W power handling with thermal resistance of 30°C/W to TAB 1, enabling reliable operation in high-density PCB layouts where thermal management is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13 V ±5% at IZT = 28.8 mA - defines nominal clamping/reference voltage with tight production control |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables robust voltage regulation in compact SMT designs without external heatsinking |
| Dynamic Impedance (ZZT) | 7.0 Ω at IZT = 28.8 mA - ensures minimal output voltage variation under dynamic load changes |
| Reverse Leakage (IR) | ≤1 µA at VR = 10.4 V - supports low-power standby modes and precision bias networks |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - allows direct thermal path to PCB copper pour or chassis for effective heat transfer |
| ESD Rating | >16 kV per Human Body Model - provides inherent robustness against handling and system-level electrostatic discharge |
Pinout & Package
Package: Powermite® surface-mount molded package with full metallic bottom and integral locking tab (TAB 1 = cathode). Cathode designated by TAB 1; mounting position unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and electrical cathode connection; must be soldered to thermal pad for rated power performance |
| Lead 2 | Anode | Standard anode connection; electrically isolated from TAB 1; used for forward bias or reverse-bias circuit return path |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling in footprint comparable to smaller discrete packages |
| Integral heat sink locking tab | TAB 1 functions as both cathode and primary thermal interface, reducing need for additional thermal vias or copper area |
| Full metallic bottom | Eliminates solder flux entrapment risk during assembly, improving long-term reliability and solder joint integrity |
| ESD robustness | >16 kV HBM rating reduces susceptibility to damage during board handling and system integration |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | 12 V nominal, DO-41 through-hole, 1 W rating, 22 Ω ZZT, no metallic thermal tab | Limited to lower-power linear regulators; requires manual insertion and lacks integrated heat sinking | Choose only for legacy through-hole designs where board real estate and thermal demands are minimal |
| BZX84-C13 | 13 V ±5%, SOT-23, 300 mW rating, 30 Ω ZZT, plastic package, no thermal tab | Suitable for signal-level clamping only; cannot sustain 3.0 W continuous dissipation or high-energy transients | Select when space is critical but power handling is below 500 mW; not interchangeable for power regulation roles |
Compared with 1N4742A and BZX84-C13, the 1PMT5928CE3/TR7 uniquely combines 13 V precision, 3.0 W capability, and integrated thermal management in a surface-mount format-enabling higher-reliability power regulation where thermal and ESD robustness are design-critical.

FAQ
What is the zener voltage tolerance for 1PMT5928CE3/TR7?
The 1PMT5928CE3/TR7 has a standard zener voltage tolerance of ±5% at 13 V, measured at 28.8 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%. This tolerance ensures predictable clamping behavior in production-grade power regulation circuits.
How is thermal performance managed in the 1PMT5928CE3/TR7 package?
The 1PMT5928CE3/TR7 uses the Powermite® package with TAB 1 as both cathode and primary thermal interface, achieving 30°C/W junction-to-TAB thermal resistance. To realize rated 3.0 W dissipation, TAB 1 must be soldered to a minimum 100 mm² copper pour with ≥4 thermal vias. This design eliminates reliance on lead-frame conduction alone, enabling stable operation in compact industrial PCBs.
Is the 1PMT5928CE3/TR7 compatible with lead-free reflow processes?
Yes, the 1PMT5928CE3/TR7 is qualified for lead-free reflow per J-STD-020, with peak temperatures up to 260°C. Its molded Powermite® package and full metallic bottom ensure mechanical stability and flux-free solder joints during standard Pb-free profiles. The device's -55°C to +150°C operating range further supports reliability after multiple reflow cycles.
What does the 'TR7' suffix indicate in 1PMT5928CE3/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 pick-and-place equipment and ensures consistent orientation (cathode TAB 1 aligned per datasheet mechanical drawing) during automated assembly-critical for maintaining process yield and thermal pad alignment.
Can the 1PMT5928CE3/TR7 replace older through-hole Zeners like 1N4742A in existing designs?
No direct replacement is possible without layout revision: the 1PMT5928CE3/TR7 uses a surface-mount Powermite® footprint incompatible with DO-41 pads. While both provide ~13 V regulation, the 1PMT5928CE3/TR7 offers 3× higher power (3.0 W vs. 1.0 W), lower impedance (7.0 Ω vs. 22 Ω), and integrated thermal sinking-requiring updated PCB thermal design and assembly programming.
