Product details
Overview
1PMT5928E3/TR13 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 signal lines.
For engineers reviewing the 1PMT5928E3/TR13 datasheet, 1PMT5928E3/TR13 pinout, 1PMT5928E3/TR13 application, or 1PMT5928E3/TR13 equivalent, key selection criteria include zener voltage accuracy (±5%), low dynamic impedance (7.0 Ω), high ESD robustness (>16 kV HBM), thermal performance (30°C/W), and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This device operates as a silicon planar Zener diode with sharp reverse breakdown at nominal 13 V, designed for stable voltage regulation under DC bias. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and eliminate solder flux entrapment during reflow.
The 1PMT5928E3/TR13 exhibits tight knee characteristics (IZK = 0.25 mA, ZZK = 550 Ω) and low reverse leakage (IR ≤ 1 µA at VR = 10.4 V), enabling reliable clamping in low-current sensing and protection circuits where stable reference voltage and minimal standby loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.0 V ±5% at IZT = 28.8 mA - defines regulated output voltage with predictable tolerance in feedback or clamp networks |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-energy transient suppression without external heatsinking |
| Dynamic Impedance (ZZT) | 7.0 Ω at IZT - ensures minimal voltage shift under load current variation, critical for stable reference accuracy |
| Thermal Resistance | 30°C/W junction-to-TAB1 - supports direct thermal coupling to PCB copper pour or metal-core substrate |
| ESD Rating | >16 kV per Human Body Model - provides intrinsic system-level ESD immunity for I/O protection without added TVS stages |
| Knee Current (IZK) | 0.25 mA - allows functional regulation down to ultra-low standby currents in battery-powered systems |
| Reverse Leakage (IR) | ≤1 µA at VR = 10.4 V - minimizes quiescent power loss in always-on monitoring circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5928B | Same 13 V nominal voltage, ±5% tolerance, but in DO-41 through-hole package; higher thermal resistance (~65°C/W) | Limited to manual or wave-soldered assemblies; unsuitable for high-density SMT layouts | Select when legacy through-hole design or higher single-pulse surge capability is required |
| MMSZ5243B | 13 V Zener in SOD-123 package; lower power rating (500 mW); higher dynamic impedance (10 Ω) | Not suitable for >500 mW continuous dissipation or high-energy transients | Select only for space-constrained, low-power biasing where thermal load is negligible |
Compared with 1N5928B and MMSZ5243B, the 1PMT5928E3/TR13 uniquely combines 3.0 W SMT power handling, 30°C/W thermal resistance, and >16 kV ESD rating-making it the only option for high-reliability, high-density, and high-transient environments requiring both regulation and robustness.

FAQ
What is the Zener voltage tolerance for the 1PMT5928E3/TR13?
The 1PMT5928E3/TR13 has a standard Zener voltage tolerance of ±5% at 13.0 V, measured at IZT = 28.8 mA with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the base part number 1PMT5928E3/TR13 specifies ±5%.
How is thermal performance specified for the 1PMT5928E3/TR13?
The 1PMT5928E3/TR13 has a thermal resistance of 30°C/W junction-to-TAB1, meaning each watt of dissipated power raises the junction temperature 30°C above the TAB1 temperature. This value assumes full solder coverage of the metallic bottom to a thermally adequate PCB pad.
Is the 1PMT5928E3/TR13 compatible with lead-free reflow processes?
Yes, the 1PMT5928E3/TR13 is qualified for lead-free reflow per J-STD-020. Its Powermite® package withstands peak temperatures up to 260°C, and the full metallic bottom ensures reliable wetting and void-free solder joints during standard profile reflow.
What does the "E3/TR13" suffix indicate in 1PMT5928E3/TR13?
The "E3" denotes tape-and-reel packaging per EIA-481 standard, and "TR13" specifies a 13-inch reel containing 12,000 units. This packaging format is optimized for high-speed SMT pick-and-place equipment and supports automated production line feeding.
Can the 1PMT5928E3/TR13 be used in parallel for higher power handling?
No-Zener diodes like the 1PMT5928E3/TR13 should not be paralleled due to mismatched VZ and dynamic impedance, which causes current hogging and thermal instability. For higher power, use a single higher-rated device or implement active current sharing with external circuitry.
