Product details
Overview
1PMT5934BE3/TR13 from Microsemi is a 24 V ±5% surface-mount Zener diode in the Powermite® package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with dynamic impedance of 19 Ω at 15.6 mA test current and reverse leakage ≤1 µA at 18.2 V. It serves as a precision voltage reference or overvoltage clamp in compact DC power rails and regulator feedback networks.
For engineers reviewing the 1PMT5934BE3/TR13 datasheet, 1PMT5934BE3/TR13 pinout, 1PMT5934BE3/TR13 application, or 1PMT5934BE3/TR13 equivalent, key selection criteria include zener voltage tolerance (±5%), 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 automation.
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 assembly.
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, and maximum power dissipation accounts for voltage rise at elevated currents and temperatures per Micro Note 202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 24 V ±5% - stable regulation point for feedback or clamping at nominal load |
| Test Current (IZT) | 15.6 mA - standardized bias condition for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZT) | 19 Ω - low AC impedance ensures minimal voltage deviation under small-signal ripple |
| Knee Impedance (ZZK) | 700 Ω - defines onset of regulation at low current (0.25 mA), critical for standby-mode stability |
| Max Reverse Leakage (IR) | ≤1 µA at 18.2 V - enables low-power sensing and battery-backed circuits without parasitic drain |
| Thermal Resistance (RθJ-TAB) | 30°C/W - quantifies junction-to-tab heat transfer efficiency; dictates heatsinking requirements |
| ESD Rating (HBM) | >16 kV - robust handling for automated SMT lines and field-deployed equipment |
Pinout & Package
The 1PMT5934BE3/TR13 uses a DO-216–compatible Powermite® surface-mount package with molded body, full metallic bottom, and integral heat sink locking tab. Cathode is unambiguously designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat path and electrical cathode connection; must be soldered to copper pour for thermal management |
| Lead 2 | Anode | Standard anode terminal; mounted on PCB pad with standard reflow profile |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5934BRLG | Same 24 V ±5%, but in DO-41 through-hole package; no metallic bottom or locking tab; RθJ-lead ≈ 65°C/W | Requires manual or wave soldering; unsuitable for high-density SMT layouts or automated insertion | Select only when legacy through-hole assembly or higher thermal margin at lower power is required |
| BZX84-C24LT1G | 24 V ±5%, SOT-23 package; 350 mW rating; ZZT = 90 Ω at 5 mA; RθJ-Ambient ≈ 300°C/W | Limited to low-power signal-level clamping; cannot sustain 3.0 W pulses or continuous regulation | Choose for space-constrained logic-level protection where power dissipation < 0.5 W |
Compared with 1N5934BRLG and BZX84-C24LT1G, the 1PMT5934BE3/TR13 uniquely delivers 3.0 W SMT power handling with integrated thermal management-enabling direct replacement of larger packages while maintaining automated manufacturability and high-reliability operation in industrial and automotive power domains.

FAQ
What is the zener voltage tolerance for 1PMT5934BE3/TR13?
The 1PMT5934BE3/TR13 has a nominal zener voltage of 24 V with a standard tolerance of ±5%, as specified in MSC0995.PDF Rev F. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the E3/TR13 variant carries the standard ±5% grade. This tolerance applies under test conditions of IZT = 15.6 mA and TL = 30°C.
How is thermal performance characterized for 1PMT5934BE3/TR13?
The 1PMT5934BE3/TR13 features a junction-to-TAB thermal resistance of 30°C/W, measured from the silicon die to TAB 1 (cathode). This value assumes proper soldering of TAB 1 to a minimum 100 mm² copper area. The metallic bottom and locking tab design directly enable this low Rθ, allowing the device to safely dissipate its full 3.0 W rating when mounted correctly-unlike conventional SMT Zeners limited to ~500 mW.
Does 1PMT5934BE3/TR13 meet industry ESD standards?
Yes, the 1PMT5934BE3/TR13 is rated for >16 kV per the Human Body Model (HBM), as confirmed in the "FEATURES" section of MSC0995.PDF. This level exceeds JEDEC JS-001 Class 3B (8 kV) and supports robust handling in automated SMT lines and field service environments without requiring additional ESD safeguards during board assembly.
What packaging format is used for 1PMT5934BE3/TR13?
The 1PMT5934BE3/TR13 is supplied in EIA-481 compliant tape-and-reel format, with 3,000 units per 7-inch reel (TR13 designation confirms this configuration). The reel meets standard pick-and-place machine requirements and includes leader/tail sections with empty pockets for feeder synchronization-ensuring reliable automated placement in high-volume manufacturing.
Can 1PMT5934BE3/TR13 be used in place of older through-hole Zeners like 1N5934B?
While the 1PMT5934BE3/TR13 matches the 24 V rating and ±5% tolerance of the 1N5934B, it is not a drop-in replacement due to differing packages (Powermite® DO-216 vs. DO-41) and thermal paths. Its TAB 1 cathode requires dedicated PCB pad design and thermal copper. However, it provides superior power density and automated assembly compatibility-making it ideal for new designs targeting miniaturization and SMT scalability.
