Product details
Overview
1PMT5928C/TR7 from Microsemi is a 13 V, ±1% 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 and ESD-protected signal lines.
For engineers reviewing the 1PMT5928C/TR7 datasheet, 1PMT5928C/TR7 pinout, 1PMT5928C/TR7 application, or 1PMT5928C/TR7 equivalent, key selection criteria include its tight 1% Zener voltage tolerance, 16 kV HBM ESD rating, full metallic bottom for flux-free reflow, integral heat sink tab, and DO-216 mechanical outline compatibility with automated placement equipment.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range (IZT = 28.8 mA). Its low dynamic impedance (7.0 Ω) and knee impedance (400 Ω at IZK = 0.25 mA) ensure stable clamping performance under varying load and transient conditions.
The Powermite® package integrates a full metallic bottom and locking tab that directly conducts heat to the PCB pad, enabling 3.0 W power handling without external heatsinking. Thermal resistance is specified as 30°C/W from junction to TAB 1, confirming its suitability for high-reliability thermal management in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.0 V ±1% at IZT = 28.8 mA - enables precise voltage reference or clamping within 0.13 V tolerance. |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - supports robust operation in thermally constrained SMT designs without derating penalties. |
| Dynamic Impedance (ZZT) | 7.0 Ω at IZT = 28.8 mA - ensures minimal output voltage variation under load current changes. |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows direct thermal path to PCB copper, simplifying thermal design. |

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, ±5%, 1.0 W, DO-41 package - lower power, looser tolerance, no integrated heat sink tab. | Not suitable for 3.0 W continuous clamping or automated SMT assembly; requires through-hole mounting. | Select only for low-power, cost-sensitive prototyping where thermal performance is secondary. |
| BZX84-C13 | 13 V, ±5%, 300 mW, SOT-23 - same nominal voltage but 10× lower power rating and no metallic thermal path. | Limited to signal-level clamping; cannot replace 1PMT5928C/TR7 in power rail regulation or surge suppression. | Use only in low-current bias networks where 1PMT5928C/TR7's 3.0 W capability is unnecessary. |
Compared with 1N4742A and BZX84-C13, the 1PMT5928C/TR7 delivers 3× higher power handling, 5× tighter voltage tolerance, and a thermally optimized SMT package-making it the sole choice for production-grade 13 V clamping in space-constrained, high-reliability systems.

FAQ
What is the Zener voltage tolerance for 1PMT5928C/TR7?
The "C" suffix in 1PMT5928C/TR7 denotes a ±1% Zener voltage tolerance at IZT = 28.8 mA and TAB 1 temperature of 30°C. This is tighter than the standard ±5% version (1PMT5928B/TR7) and critical for applications requiring high initial accuracy without post-manufacturing calibration. The 1PMT5928C/TR7 achieves this via binning during final test and is documented in MSC0995 Rev F.
How is thermal performance achieved in the 1PMT5928C/TR7 Powermite® package?
The 1PMT5928C/TR7 uses a full metallic bottom and integral locking tab to conduct heat directly from the silicon junction to the PCB copper pad, achieving a thermal resistance of 30°C/W junction-to-TAB1. This allows full 3.0 W power dissipation at TAB 1 = 60°C-unlike plastic-packaged Zeners that require derating above 25°C ambient. The design eliminates reliance on air convection or external heatsinks.
Is 1PMT5928C/TR7 compatible with automated SMT assembly processes?
Yes, the 1PMT5928C/TR7 is explicitly designed for compatibility with automatic insertion equipment. Its Powermite® package features a symmetric, self-centering geometry and flat metallic bottom that prevents tombstoning during reflow. It ships in EIA-481-compliant tape-and-reel format (7″ reel, 3,000 pcs), and its DO-216AA outline matches industry-standard pick-and-place nozzle profiles.
What does the "TR7" suffix indicate for 1PMT5928C/TR7?
The "TR7" suffix specifies tape-and-reel packaging per EIA-481 standard on a 7-inch reel containing 3,000 units. This is the standard production format for SMT use and ensures consistent orientation, spacing, and moisture sensitivity level (MSL) compliance. It is distinct from bulk or ammo-pack variants and confirms factory-tested, traceable lot control for high-volume manufacturing.
Can 1PMT5928C/TR7 be used as an ESD protection device?
Yes, the 1PMT5928C/TR7 has an ESD rating exceeding 16 kV per Human Body Model (HBM), verified per ANSI/ESDA/JEDEC JS-001. Its low dynamic impedance (7.0 Ω) and fast response enable effective clamping of ESD transients on signal or power lines. However, it is not a dedicated TVS diode-its primary function remains precision voltage regulation, so system-level testing is required for full IEC 61000-4-2 compliance.
