Product details
Overview
1PMT5934B/TR13 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 700 µA max reverse leakage at 18.2 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5934B/TR13 datasheet, 1PMT5934B/TR13 pinout, 1PMT5934B/TR13 application, or 1PMT5934B/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance, and compatibility with automated SMT assembly using EIA-481 tape-and-reel packaging.
Technical Context
This device operates as a two-terminal voltage-regulating diode with sharp Zener breakdown at 24 V nominal. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and mechanical stability during reflow soldering.
The 1PMT5934B/TR13 exhibits 19 Ω dynamic impedance at IZT = 15.6 mA and maintains ≤700 µA reverse leakage at VR = 18.2 V, supporting stable regulation under varying load and temperature conditions across –55°C to +150°C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 24 V ±5% at IZT = 15.6 mA - defines stable regulation point for feedback or clamping circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-power handling in compact SMT footprint |
| Dynamic Impedance ZZT | 19 Ω at IZT = 15.6 mA - ensures minimal output voltage variation under load transients |
| Reverse Leakage IR | ≤700 µA at VR = 18.2 V - guarantees low quiescent current in standby or sensing applications |
| Thermal Resistance | 30°C/W junction-to-TAB - allows direct thermal coupling to PCB copper for passive cooling |
| ESD Rating | >16 kV per Human Body Model - provides robustness against handling and system-level ESD events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMZ24A-E3/57T (Vishay) | Same 24 V ±5%, DO-214AC package, 3.0 W rating, but higher ZZT = 25 Ω and 50°C/W thermal resistance | Lacks integral heat-sink tab; requires larger thermal pad area to achieve equivalent power derating | Prefer 1PMT5934B/TR13 where board space is constrained and thermal performance is critical |
| BZX84-C24LT1G (onsemi) | 24 V ±5%, SOT-23 package, 300 mW rating, ZZT = 90 Ω, 100°C/W thermal resistance | Not suitable for >300 mW continuous dissipation; limited to low-power signal-level clamping | Select 1PMT5934B/TR13 when 3.0 W clamping or regulation is required in SMT form factor |
Compared with SMZ24A-E3/57T and BZX84-C24LT1G, the 1PMT5934B/TR13 delivers superior thermal performance (30°C/W vs. ≥50°C/W), higher power capability (3.0 W vs. ≤300 mW), and integrated mechanical heat sinking-making it uniquely suited for high-reliability 24 V power rail stabilization where thermal management and board area are constrained.

FAQ
What is the Zener voltage tolerance and test condition for 1PMT5934B/TR13?
The 1PMT5934B/TR13 has a nominal Zener voltage of 24 V with a standard tolerance of ±5%, measured at IZT = 15.6 mA with TAB 1 temperature held at 30°C. Voltage measurement must be performed within 20 seconds of applying DC current to avoid self-heating effects. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, respectively.
How is thermal performance specified for 1PMT5934B/TR13?
The 1PMT5934B/TR13 has a junction-to-TAB thermal resistance of 30°C/W, meaning each watt dissipated raises the junction temperature 30°C above TAB 1 temperature. Full 3.0 W power rating is valid only when TAB 1 is maintained at ≤60°C. This specification assumes direct soldering of TAB 1 to a thermally optimized PCB copper area.
Does 1PMT5934B/TR13 meet automotive reliability standards?
The 1PMT5934B/TR13 operates across –55°C to +150°C junction temperature and has >16 kV HBM ESD rating, aligning with core stress requirements of AEC-Q101. While not officially AEC-Q101 certified as a standalone part, its construction, testing, and qualification history support use in automotive body control and under-hood modules where full qualification is managed at the system level.
What packaging format is used for 1PMT5934B/TR13?
The 1PMT5934B/TR13 is supplied in EIA-481 compliant tape-and-reel format. The "TR13" suffix indicates 13-inch reels containing 12,000 units. Reel dimensions, sprocket hole pitch, and pocket geometry conform to industry-standard automated pick-and-place equipment requirements for DO-216AA devices.
Can 1PMT5934B/TR13 replace through-hole Zener diodes like 1N5249B in new designs?
Yes-the 1PMT5934B/TR13 offers identical 24 V ±5% regulation and 3.0 W power rating as the through-hole 1N5249B but in a surface-mount Powermite® package. Its TAB 1 cathode provides superior thermal performance versus axial leads, enabling higher power density. Layout redesign is required due to DO-216AA footprint, but no electrical redesign is needed for equivalent regulation function.
