Product details
Overview
1PMT5926C/TR13 from Microsemi is a 11 V, ±1% tolerance surface-mount Zener diode in the Powermite® 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 thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in power supply regulation circuits.
For engineers reviewing the 1PMT5926C/TR13 datasheet, 1PMT5926C/TR13 pinout, 1PMT5926C/TR13 application, or 1PMT5926C/TR13 equivalent, key selection criteria include its tight 1% voltage tolerance, ESD rating >16 kV HBM, low reverse leakage (≤1 µA at 8.4 V), full metallic bottom for flux-free assembly, and compatibility with automated insertion equipment.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its design centers on thermal management via the metallic TAB 1 (cathode) acting as both electrical terminal and integral heat sink, supported by a locking tab that enhances mechanical retention during reflow.
The device meets MIL-STD-750D test methods for reliability and is characterized at TL = 30°C with Zener voltage measured 20 seconds after DC current application. Dynamic impedance is defined using 60 Hz RMS AC current equal to 10% of IZT, per Micro Note 202 for voltage-current deviation analysis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11.0 V ±1% at IZT = 34.1 mA - ensures precise clamping or reference within 0.11 V tolerance band |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-power regulation without external heatsinking in compact layouts |
| Dynamic Impedance (ZZT) | 5.5 Ω at IZT - minimizes output voltage variation under dynamic load transients |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows accurate thermal modeling when TAB 1 is soldered to copper pour |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF11A (ON Semiconductor) | 11 V, ±5%, 1 W rating, SOD-123 package, 100 Ω ZZT | Limited to lower-energy transients; unsuitable for sustained 3 W dissipation | Select when cost sensitivity outweighs power handling and precision needs |

FAQ
What is the Zener voltage tolerance for 1PMT5926C/TR13?
The "C" suffix in 1PMT5926C/TR13 denotes ±1% Zener voltage tolerance at IZT = 34.1 mA and TL = 30°C. This tighter tolerance improves consistency in precision reference and clamping applications compared to standard ±5% versions like 1PMT5926B/TR13. The 1PMT5926C/TR13 achieves this via post-process screening and binning.
How is thermal performance managed in the 1PMT5926C/TR13 package?
The 1PMT5926C/TR13 uses its metallic TAB 1 as the primary thermal path, with a specified junction-to-TAB thermal resistance of 30°C/W. Effective heat dissipation requires soldering TAB 1 to ≥100 mm² of 1 oz copper on the PCB. The locking tab mechanically secures the device during thermal cycling, preventing solder joint fatigue.
Can 1PMT5926C/TR13 be used in place of through-hole Zener diodes like 1N5242B?
No-1PMT5926C/TR13 is not a drop-in replacement for 1N5242B due to differing packages (Powermite® vs. DO-35), thermal paths (TAB 1 vs. axial leads), and derating curves. While both are 11 V Zeners, the 1PMT5926C/TR13 requires PCB copper area for cooling and has different surge handling per MIL-STD-750D, unlike the 1N5242B's lead-frame thermal path.
What does the "TR13" suffix indicate in 1PMT5926C/TR13?
The "TR13" suffix specifies tape-and-reel packaging per EIA-481 standard on a 13-inch reel containing 12,000 units. This format supports high-volume automated pick-and-place assembly. It does not affect electrical characteristics-the 1PMT5926C/TR13 shares identical Zener voltage, impedance, and thermal specs with the same device in 7-inch reel (TR7) or cut-tape formats.
Is 1PMT5926C/TR13 suitable for automotive AEC-Q200 compliance?
The 1PMT5926C/TR13 is not AEC-Q200 qualified. While it operates from −55°C to +150°C and has >16 kV HBM ESD rating, Microsemi did not submit this specific Powermite® Zener family for AEC-Q200 stress testing. For automotive applications requiring qualification, consult Microchip's AEC-Q200-certified Zener portfolio or perform full component-level validation per vehicle OEM requirements.
