Product details
Overview
1PMT5935CE3/TR13 from Microsemi is a 27 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 23 Ω dynamic impedance at 13.9 mA test current and 1 µA max reverse leakage at 20.6 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5935CE3/TR13 datasheet, 1PMT5935CE3/TR13 pinout, 1PMT5935CE3/TR13 application, or 1PMT5935CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance (700 Ω at 0.25 mA), and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This device operates as a two-terminal voltage-regulating diode with cathode designated by TAB 1. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and eliminate solder flux entrapment during reflow.
Electrical behavior is defined at TL = 30°C with Zener voltage measured 20 seconds after DC current application; dynamic impedance is derived using 60 Hz RMS AC current equal to 10% of IZT. Thermal resistance is 30°C/W from junction to TAB 1, enabling stable regulation under sustained 3.0 W dissipation when mounted on thermally adequate PCB copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 27 V ±5% - sets precise clamping threshold for 24 V nominal systems |
| Test Current (IZT) | 13.9 mA - operating point where VZ and ZZT are specified |
| Dynamic Impedance (ZZT) | 23 Ω - determines voltage deviation under load current variation |
| Max Reverse Leakage (IR) | 1 µA at 20.6 V - ensures minimal standby power loss in high-impedance bias networks |
| Thermal Resistance (RθJ-TAB) | 30°C/W - defines temperature rise per watt dissipated at TAB 1 |
| ESD Rating (HBM) | >16 kV - provides robust handling immunity without external protection |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables higher power density than DO-214/DO-41 packages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ27A | TVS diode (unidirectional), 27 V breakdown, 1500 W peak pulse power, higher leakage (~5 µA at 22 V) | Designed for transient suppression, not precision DC regulation | Select for surge-heavy environments (e.g., motor drives); avoid where low DC leakage or tight VZ tolerance is required |
| BZX84-C27 | SOT-23 Zener, 27 V ±5%, 300 mW rating, 500 Ω ZZK, no metallic thermal path | Limited to low-power bias/reference roles due to 0.3 W rating and higher thermal resistance | Use in space-constrained low-current circuits; not suitable for 3.0 W continuous clamping or high-reliability thermal cycling |
Compared with SMCJ27A and BZX84-C27, the 1PMT5935CE3/TR13 uniquely combines 3.0 W DC power handling, 30°C/W thermal resistance, and 1 µA reverse leakage-making it optimal for industrial DC rail clamping where both precision and sustained power dissipation matter.

FAQ
What is the Zener voltage tolerance for 1PMT5935CE3/TR13?
The 1PMT5935CE3/TR13 has a nominal Zener voltage of 27 V with a standard tolerance of ±5%, as confirmed in the MSC0995.PDF datasheet. This tolerance applies under test conditions of IZT = 13.9 mA and TL = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the CE3 variant specifies ±5%.
How is thermal management handled in the 1PMT5935CE3/TR13 package?
The 1PMT5935CE3/TR13 uses the Powermite® package with a full metallic bottom and integral locking tab that contacts the PCB directly, achieving a junction-to-TAB thermal resistance of 30°C/W. This design allows reliable 3.0 W DC power dissipation when TAB 1 is thermally anchored to ≥1 cm² of 2-oz copper, eliminating need for external heatsinks in most industrial layouts.
Does 1PMT5935CE3/TR13 meet industry ESD standards?
Yes, the 1PMT5935CE3/TR13 is rated for >16 kV per Human Body Model (HBM), as stated in the MSC0995.PDF features list. This level exceeds IEC 61000-4-2 Level 4 (8 kV contact) and supports robust handling in automated SMT lines without requiring additional ESD mitigation during board assembly.
What is the maximum reverse leakage current for 1PMT5935CE3/TR13?
The maximum reverse leakage current for 1PMT5935CE3/TR13 is 1 µA at a reverse voltage of 20.6 V, per the Electrical Characteristics table in MSC0995.PDF. This low leakage supports energy-efficient designs in battery-powered or high-impedance bias networks where standby current must be minimized.
Is 1PMT5935CE3/TR13 compatible with standard SMT assembly processes?
Yes, the 1PMT5935CE3/TR13 is supplied in EIA-481 compliant tape-and-reel format (7″ reel: 3,000 pcs; 13″ reel: 12,000 pcs) and is explicitly designed for compatibility with automatic insertion equipment. Its Powermite® package geometry and locking tab ensure stable placement and alignment during pick-and-place operations without tombstoning or misregistration.
