Product details
Overview
1PMT5926CE3/TR7 from Microsemi is a 11 V, ±5% tolerance Zener diode in Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 5.5 Ω dynamic impedance at 34.1 mA test current and 1 µA max reverse leakage at 8.4 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5926CE3/TR7 datasheet, 1PMT5926CE3/TR7 pinout, 1PMT5926CE3/TR7 application, or 1PMT5926CE3/TR7 equivalent, key selection criteria include zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and mechanical stability during reflow soldering.
The device exhibits low reverse leakage (≤1 µA at VR = 8.4 V) and stable dynamic impedance (5.5 Ω at IZT = 34.1 mA), enabling reliable clamping and reference functions in temperature-varying environments up to +150°C junction temperature.

FAQ
What is the zener voltage tolerance for 1PMT5926CE3/TR7?
The 1PMT5926CE3/TR7 has a standard zener voltage tolerance of ±5% at 11 V, measured at 34.1 mA test current and TAB 1 temperature of 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the CE3/TR7 variant specifies ±5%.
How is thermal management implemented in the 1PMT5926CE3/TR7 package?
The 1PMT5926CE3/TR7 uses Microsemi's Powermite® package with a full metallic bottom and integral locking tab that acts as a direct thermal path from the silicon junction to the PCB. Its specified thermal resistance is 30°C/W junction-to-TAB, requiring proper soldering of TAB 1 to a thermally enhanced pad for full 3.0 W operation.
Can 1PMT5926CE3/TR7 be used in automotive applications?
Yes, the 1PMT5926CE3/TR7 is qualified for automotive use with a junction temperature range of –55°C to +150°C and >16 kV HBM ESD rating. Its robust Powermite® package and 3.0 W clamping capability make it suitable for body control modules, LIN bus protection, and engine control unit voltage supervision circuits.
What does the 'TR7' suffix indicate in 1PMT5926CE3/TR7?
The 'TR7' suffix denotes tape-and-reel packaging per EIA Standard 481, with 7-inch reels containing 3,000 units. This format is optimized for high-speed SMT pick-and-place equipment and ensures consistent orientation and feed reliability during automated assembly of the 1PMT5926CE3/TR7.
Is the cathode of 1PMT5926CE3/TR7 marked on the device body?
No, the 1PMT5926CE3/TR7 does not feature a visible cathode marking on its molded body. Cathode identification is defined mechanically: TAB 1 is the cathode terminal, and the device must be oriented on the PCB so that TAB 1 aligns with the designated cathode pad per the Powermite® mechanical drawing and DO-216 outline.
