Product details
Overview
1PMT5934AE3/TR7 from Microsemi is a 24 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 19 Ω dynamic impedance at 15.6 mA test current and 1 µA max reverse leakage at 18.2 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5934AE3/TR7 datasheet, 1PMT5934AE3/TR7 pinout, 1PMT5934AE3/TR7 application, or 1PMT5934AE3/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 (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 applying DC test current; dynamic impedance is derived 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) | 24 V ±5% at IZT = 15.6 mA - sets stable reference point for regulation or clamping |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - defines maximum continuous thermal load under controlled heatsinking |
| Dynamic Impedance (ZZT) | 19 Ω at IZT - determines output voltage stability under varying load current |
| Knee Impedance (ZZK) | 700 Ω at IZK = 0.25 mA - indicates regulation onset sharpness near minimum operating current |
| Reverse Leakage (IR) | ≤1 µA at VR = 18.2 V - ensures minimal standby power loss in high-impedance bias networks |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt dissipated into the mounting pad |
| ESD Rating | >16 kV per Human Body Model - supports robust handling in unshielded manufacturing environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ24A | TVS diode with 24 V standoff, 30 kW peak pulse power, higher clamping voltage (38.9 V), unidirectional | Designed for surge suppression, not precision DC regulation | Select only for transient protection; not suitable as voltage reference due to wide VBR tolerance and lack of tight VZ spec |
| BZX84-C24 | SOT-23 Zener, 24 V ±5%, 300 mW rating, 85 Ω ZZT at 5 mA, no metallic thermal tab | Limited to low-power bias/reference use; cannot dissipate 3 W continuously | Use where board space is constrained and power < 0.3 W; avoid in thermally demanding 24 V rail clamping |
Compared with SMCJ24A and BZX84-C24, the 1PMT5934AE3/TR7 uniquely combines 3.0 W continuous dissipation, 30°C/W thermal resistance via TAB 1, and tight 24 V regulation-making it suitable for high-reliability DC voltage stabilization where both power handling and precision matter.

FAQ
What is the zener voltage tolerance for 1PMT5934AE3/TR7?
The 1PMT5934AE3/TR7 has a nominal zener voltage of 24 V with a standard tolerance of ±5%, as specified in MSC0995 Rev F. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request. Voltage is measured at IZT = 15.6 mA with TAB 1 held at 30°C, 20 seconds after DC current application. This tolerance directly impacts regulation accuracy in reference and clamping circuits using the 1PMT5934AE3/TR7.
How is thermal performance characterized for 1PMT5934AE3/TR7?
The 1PMT5934AE3/TR7 features a thermal resistance of 30°C/W from junction to TAB 1, enabling effective heat transfer when TAB 1 is soldered to a copper pour. Its Powermite® package uses a full metallic bottom and locking tab to maximize conduction. At 3.0 W dissipation, junction temperature rise is ~90°C above TAB 1 temperature-so maintaining TAB 1 ≤60°C ensures junction stays within the -55°C to +150°C rating. This thermal behavior is critical for reliability in continuous 24 V rail clamping applications using the 1PMT5934AE3/TR7.
Can 1PMT5934AE3/TR7 be used in automotive applications?
Yes, the 1PMT5934AE3/TR7 is qualified for automotive use with junction/storage temperature range of -55°C to +150°C and >16 kV HBM ESD rating. Its 3.0 W power rating and 30°C/W thermal resistance support robust transient clamping in 24 V body control modules during load-dump events. However, it is not AEC-Q200 certified out-of-box; system-level validation per ISO 7637-2 Pulse 5a is recommended. The 1PMT5934AE3/TR7 delivers proven performance in automotive-grade designs where discrete Zener clamping is required.
What packaging format does 1PMT5934AE3/TR7 ship in?
The 1PMT5934AE3/TR7 ships in EIA-481 compliant tape-and-reel format: 3,000 pieces per 7-inch reel or 12,000 pieces per 13-inch reel. The "TR7" suffix explicitly denotes the 7-inch tape-and-reel variant. This packaging supports fully automated SMT placement equipment and aligns with industry-standard feeder compatibility. The Powermite® package's locking tab and flat bottom ensure stable orientation and reliable pick-and-place yield-key advantages confirmed in production lines using the 1PMT5934AE3/TR7.
Is there a lead-free version of 1PMT5934AE3/TR7?
Yes, the 1PMT5934AE3/TR7 is RoHS-compliant and manufactured with lead-free terminations, consistent with Microsemi's transition to Pb-free processes per J-STD-609. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 requirements and is compatible with standard SnAgCu reflow profiles. No special handling or baking is required prior to assembly. This lead-free construction ensures compliance for global electronics manufacturing while preserving all electrical and thermal specifications of the 1PMT5934AE3/TR7.
