Product details
Overview
1PMT5928BE3/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 protection circuits.
For engineers reviewing the 1PMT5928BE3/TR13 datasheet, 1PMT5928BE3/TR13 pinout, 1PMT5928BE3/TR13 application, or 1PMT5928BE3/TR13 equivalent, key selection criteria include its 13 V nominal Zener voltage, 3.0 W power handling in a DO-216 (Powermite®) package, low reverse leakage (<1 µA at 10.4 V), 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 under varying load and temperature conditions. Its Powermite® package features a full metallic bottom and integral locking tab that functions as both mechanical anchor and heat sink, enabling efficient thermal conduction from junction to PCB via TAB 1.
The device exhibits tight voltage regulation with 7.0 Ω dynamic impedance at IZT = 28.8 mA and maintains <1 µA reverse leakage up to 10.4 V. Junction-to-TAB1 thermal resistance is specified at 30°C/W, supporting reliable operation within -55°C to +150°C storage and junction temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5928BRLG | Same 13 V ±5%, but in DO-41 through-hole package; no metallic thermal tab; 1.2 W rating | Limited to lower-power designs; requires PCB hole and manual/automated through-hole insertion | Select when legacy through-hole assembly or lower thermal demand applies |
| BZX84-C13 | 13 V ±5%, SOT-23 package; 300 mW rating; 30 Ω dynamic impedance; no integrated heatsink tab | Suitable only for signal-level clamping; cannot sustain 3.0 W pulse or continuous dissipation | Select for space-constrained logic-level protection where power handling is secondary |

FAQ
What is the Zener voltage tolerance for 1PMT5928BE3/TR13?
The 1PMT5928BE3/TR13 has a nominal Zener voltage of 13.0 V with a standard tolerance of ±5%, as confirmed in the MSC0995.PDF datasheet. This tolerance applies at IZT = 28.8 mA and TC = 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, but the E3/TR13 variant uses the standard ±5% grade.
How is thermal management handled in the 1PMT5928BE3/TR13 package?
The 1PMT5928BE3/TR13 uses the Powermite® DO-216 package with TAB 1 serving as both cathode and primary thermal interface. Its 30°C/W junction-to-TAB1 thermal resistance requires direct soldering of TAB 1 to a copper thermal pad on the PCB to achieve the full 3.0 W power rating at 60°C case temperature.
Does 1PMT5928BE3/TR13 meet industry ESD standards?
Yes, the 1PMT5928BE3/TR13 is rated for >16 kV per the Human Body Model (HBM), as stated in the MSC0995.PDF features list. This exceeds IEC 61000-4-2 Level 4 (8 kV contact) and qualifies it for use as a primary ESD clamp in industrial and automotive interfaces without supplemental protection.
What is the maximum reverse leakage current for 1PMT5928BE3/TR13?
Per the MSC0995.PDF Electrical Characteristics table, the 1PMT5928BE3/TR13 exhibits a maximum reverse leakage current IR of 1 µA at VR = 10.4 V (i.e., 80% of nominal VZ). This low leakage supports energy-efficient operation in battery-powered or always-on circuits.
Is 1PMT5928BE3/TR13 compatible with automated SMT assembly processes?
Yes, the 1PMT5928BE3/TR13 is explicitly designed for compatibility with automatic insertion equipment. Its Powermite® package includes a unique locking tab and full metallic bottom to prevent solder flux entrapment-features validated in the MSC0995.PDF Mechanical Characteristics section-and is supplied in EIA-481 tape-and-reel format (TR13 = 13-inch reel, 12,000 pieces).
