Product details
Overview
1PMT5928A/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 and ESD-protected I/O circuits.
For engineers reviewing the 1PMT5928A/TR7 datasheet, 1PMT5928A/TR7 pinout, 1PMT5928A/TR7 application, or 1PMT5928A/TR7 equivalent, key selection criteria include its 13 V nominal Zener voltage, 3.0 W power handling in a DO-216 (Powermite®) package, low 7.0 Ω dynamic impedance, >16 kV HBM ESD rating, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations and temperature shifts. Its Powermite® package features a full metallic bottom and integral locking tab acting as a heat sink, enabling efficient thermal transfer from junction to PCB via TAB 1.
The device exhibits tight knee characteristics (IZK = 0.25 mA, ZZK = 550 Ω) and low reverse leakage (IR ≤ 1 µA at VR = 10.4 V), supporting reliable clamping in low-current protection circuits while sustaining 9.9 mA maximum Zener current under full 3.0 W dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13 V ±5% at IZT = 28.8 mA - defines stable regulation point for reference or clamp circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-power SMT voltage regulation without through-hole mounting |
| Dynamic Impedance (ZZT) | 7.0 Ω at IZT - ensures minimal output voltage variation under changing load current |
| Thermal Resistance | 30°C/W junction-to-TAB1 - supports thermal design with direct PCB copper pad conduction |
| ESD Rating | >16 kV HBM - provides robust input/output protection without external TVS staging |
| Knee Current (IZK) | 0.25 mA - allows effective regulation onset at very low standby currents |
| Reverse Leakage (IR) | ≤1 µA at VR = 10.4 V - minimizes quiescent power loss in battery-backed systems |
Pinout & Package
Package: DO-216 (Powermite®) - molded surface-mount package with full metallic bottom and integral heat-sink locking tab; cathode designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal; must be soldered to large copper area for thermal management |
| Lead 2 | Anode | Signal-side connection; electrically isolated from TAB 1; used for 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 smaller than SMA |
| Integral heat-sink locking tab | Provides mechanical anchoring and direct thermal path from junction to PCB copper, reducing θJA by ~40% vs standard SOD-123 |
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and void-free solder joints |
| ESD robustness | >16 kV HBM rating allows direct use on exposed ports without additional ESD protection components |
| Tight Zener tolerance options | ±5% standard; ±2% (suffix C) and ±1% (suffix D) available for precision reference applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF13A (ON Semiconductor) | Same 13 V nominal, but 1.0 W rating and SOD-123 package; higher ZZT (15 Ω) | Limited to low-power signal clamping; unsuitable for 3 W regulation | Select when board space is constrained and power < 1 W; avoid for thermal-critical 3 W designs |
| BZX84-C13 (Diodes Inc.) | 13 V ±5%, SOT-23 package, 300 mW rating, 30 Ω ZZT, no metallic heat sink | Only viable for signal-level reference; cannot replace 1PMT5928A/TR7 in power regulation | Use only in low-current bias networks; requires derating above 50°C ambient |
Compared with SMF13A and BZX84-C13, the 1PMT5928A/TR7 delivers triple the power handling and half the dynamic impedance in a thermally optimized package-making it the sole choice for 3 W SMT Zener regulation where thermal performance and stability are critical.

FAQ
What is the Zener voltage tolerance for 1PMT5928A/TR7?
The 1PMT5928A/TR7 has a standard Zener voltage tolerance of ±5% at 13 V nominal, measured at 28.8 mA test current and TAB 1 temperature of 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request, but the base 1PMT5928A/TR7 part uses the ±5% grade per MSC0995 Rev F specification.
Can 1PMT5928A/TR7 be used in place of through-hole Zener diodes like 1N5242B?
Yes, the 1PMT5928A/TR7 can replace 1N5242B (13 V, 500 mW) in many applications-but only where thermal design accommodates its 3.0 W rating. Unlike the 1N5242B's axial leaded package, the 1PMT5928A/TR7 requires a dedicated thermal pad on TAB 1 and proper PCB copper area to manage heat; it is not a drop-in mechanical replacement.
What is the maximum Zener current (IZM) for 1PMT5928A/TR7?
The maximum Zener current IZM for 1PMT5928A/TR7 is 9.9 mA, calculated based on its 3.0 W power rating and 13 V nominal Zener voltage (IZM = PZ / VZ ≈ 3.0 W / 13 V). This value assumes TAB 1 is maintained at ≤60°C; actual usable current decreases with rising thermal resistance or ambient temperature.
Does 1PMT5928A/TR7 have polarity marking, and how is cathode identified?
Yes, the 1PMT5928A/TR7 cathode is unambiguously designated by TAB 1-the large metallic bottom pad-which must be connected to the more positive potential in Zener operation. The anode is Lead 2 (top-side gull-wing lead), and no band or dot marking is used; polarity is defined solely by physical terminal assignment per MSC0995 mechanical drawing.
Is tape-and-reel packaging available for 1PMT5928A/TR7, and what are the standard reel sizes?
Yes, 1PMT5928A/TR7 is supplied in EIA-481 compliant tape-and-reel packaging: standard 7-inch reels contain 3,000 pieces, and 13-inch reels contain 12,000 pieces. The "/TR7" suffix explicitly denotes 7-inch tape-and-reel packaging per Microsemi's ordering nomenclature in MSC0995.
