Product details
Overview
1PMT5928B/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 protection circuits.
For engineers reviewing the 1PMT5928B/TR13 datasheet, 1PMT5928B/TR13 pinout, 1PMT5928B/TR13 application, or 1PMT5928B/TR13 equivalent, key selection criteria include its 13 V nominal Zener voltage, 3.0 W power handling in a DO-216 outline, low 7.0 Ω Zener impedance, ESD rating >16 kV HBM, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load or line conditions. Its Powermite® package features a full metallic bottom and integral heat-sink locking tab, enabling efficient thermal transfer from junction to PCB via TAB 1 (cathode).
Electrical behavior is defined at TL = 30°C with IZT = 28.8 mA; Zener voltage drift with temperature is managed by design, and knee current IZK = 0.25 mA ensures stable conduction onset. Reverse leakage IR ≤ 1 µA at VR = 9.9 V confirms tight leakage control for low-power biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 13.0 V ±5% - precise clamping threshold for 12 V rail protection or reference generation |
| Test Current IZT | 28.8 mA - operating point where VZ and ZZT are specified; sets minimum bias for stable regulation |
| Dynamic Impedance ZZT | 7.0 Ω - low AC impedance ensures minimal output voltage variation under dynamic load changes |

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, 1 W rating, DO-41 through-hole package, 20 Ω ZZT at 21 mA | Lower power handling and no integrated heat sink; requires larger PCB area and manual assembly | Select when cost sensitivity outweighs power density and automated assembly needs |
| BZX84-C13 | 13 V nominal, 300 mW rating, SOT-23 package, 30 Ω ZZT at 5 mA | Insufficient for 3 W surge clamping; suitable only for low-current biasing, not power regulation | Choose only for space-constrained low-power references where thermal performance is secondary |

FAQ
What is the Zener voltage tolerance for 1PMT5928B/TR13?
The 1PMT5928B/TR13 has a standard Zener voltage tolerance of ±5% at 13.0 V, measured at IZT = 28.8 mA and TAB 1 temperature of 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request, but the base 1PMT5928B/TR13 part retains the ±5% specification as documented in MSC0995 Rev F.
How is thermal management handled for 1PMT5928B/TR13 in PCB layout?
Thermal management for 1PMT5928B/TR13 relies on direct conduction from the junction to TAB 1 (cathode), which serves as the primary thermal path. Designers must connect TAB 1 to a minimum 100 mm² copper pour on the PCB layer to achieve the rated 3.0 W dissipation at TAB 1 = 60°C. The Powermite® package's full metallic bottom and locking tab enhance this conduction without requiring additional heatsinks.
Is 1PMT5928B/TR13 compatible with lead-free reflow processes?
Yes, 1PMT5928B/TR13 is qualified for lead-free reflow soldering per J-STD-020. Its Powermite® package withstands peak temperatures up to 260°C for 30 seconds. The full metallic bottom prevents flux entrapment, reducing void risk during reflow-making it suitable for high-yield automated SMT lines processing RoHS-compliant assemblies.
What is the maximum reverse leakage current for 1PMT5928B/TR13 at 9.9 V?
The maximum reverse leakage current IR for 1PMT5928B/TR13 is 1 µA at VR = 9.9 V, as specified in the Electrical Characteristics table of MSC0995. This low leakage supports accurate biasing in high-impedance sensor interfaces and ensures minimal quiescent current draw in battery-critical applications using the 1PMT5928B/TR13.
Does 1PMT5928B/TR13 have a defined cathode marking, and how is polarity identified?
Yes, polarity for 1PMT5928B/TR13 is unambiguously designated: TAB 1 is the cathode, as stated in the Mechanical Characteristics section of MSC0995. The device uses a DO-216 outline with no color band or ink marking-the physical location of TAB 1 (larger metallized pad) serves as the sole polarity indicator during placement and inspection.
