Product details
Overview
1PMT5936AE3/TR7 from Microsemi is a 30 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 12.5 mA test current (IZT), 28 Ω dynamic impedance (ZZT), and 1 µA max reverse leakage at 22.8 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5936AE3/TR7 datasheet, 1PMT5936AE3/TR7 pinout, 1PMT5936AE3/TR7 application, or 1PMT5936AE3/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, and compatibility with automated SMT assembly using EIA-481 tape-and-reel packaging.
Technical Context
This Zener diode operates in reverse breakdown mode to regulate or clamp voltage with stable performance across -55°C to +150°C junction temperature range. Its full metallic bottom and integral locking tab provide mechanical stability and enhanced thermal conduction to the PCB pad.
The device exhibits tight voltage regulation under defined test conditions: VZ measured at IZT = 12.5 mA with TAB temperature held at 30°C; dynamic impedance ZZT = 28 Ω derived from 10% AC superimposition on IZT at 60 Hz; and reverse leakage IR ≤ 1 µA at VR = 22.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±5% - defines clamping threshold for overvoltage protection or reference accuracy in feedback loops |
| Test Current (IZT) | 12.5 mA - standardized operating point for VZ measurement and thermal design basis |
| Dynamic Impedance (ZZT) | 28 Ω - determines voltage deviation under load transients; lower value improves regulation fidelity |
| Max Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling with PCB thermal management |
| Junction-to-TAB Thermal Resistance | 30°C/W - quantifies thermal path efficiency from die to mounting pad; critical for derating calculations |
| ESD Rating (HBM) | >16 kV - ensures robustness against electrostatic discharge during handling and board assembly |
| Reverse Leakage (IR) | ≤1 µA at 22.8 V - limits standby current in high-impedance bias networks or sensing circuits |
Pinout & Package
Package: Powermite® (DO-216AA) surface-mount molded case with full metallic bottom and integral heat-sink locking tab; cathode designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5357B | Same 30 V nominal Zener voltage, but DO-204AL (DO-41) through-hole package; 5 W rating; higher thermal resistance (~50°C/W) | Suitable only where through-hole assembly and higher power margin are acceptable; not SMT-compatible | Select 1PMT5936AE3/TR7 when automated SMT, space constraints, or thermal performance on PCB are priorities |
| BZX84-C30 | SOT-23 package; 30 V ±5%; 300 mW rating; ZZT ≈ 40 Ω; no metallic heat-sink tab | Limited to low-power signal-level clamping; insufficient for 3 W continuous dissipation | Choose 1PMT5936AE3/TR7 for applications requiring >1 W sustained power handling and superior thermal coupling |
Compared with 1N5357B and BZX84-C30, the 1PMT5936AE3/TR7 uniquely combines SMT compatibility, 3.0 W power capability, 30°C/W thermal resistance, and >16 kV ESD robustness-making it optimal for space-constrained, thermally demanding industrial and automotive power-clamp designs.

FAQ
What is the Zener voltage tolerance for 1PMT5936AE3/TR7?
The 1PMT5936AE3/TR7 has a standard Zener voltage tolerance of ±5% at 30 V, measured at IZT = 12.5 mA with TAB temperature maintained at 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request, but the E3/TR7 variant specifically denotes the ±5% version in 3,000-piece EIA-481 tape-and-reel packaging.
How is thermal performance specified for 1PMT5936AE3/TR7?
The 1PMT5936AE3/TR7 specifies a junction-to-TAB thermal resistance of 30°C/W, meaning each watt of dissipated power raises the junction temperature 30°C above the TAB (cathode) temperature. This value assumes proper soldering of TAB 1 to a minimum 100 mm² copper area; actual thermal performance depends on PCB layout and airflow.
Can 1PMT5936AE3/TR7 be used in place of through-hole Zeners like 1N5357B?
No direct substitution is recommended without redesign. While both offer 30 V Zener voltage, the 1PMT5936AE3/TR7 uses a surface-mount Powermite® package with integrated heat-sink tab and 3.0 W rating at 60°C TAB, whereas 1N5357B is through-hole DO-41 rated for 5 W but with higher thermal resistance. PCB layout, thermal management, and assembly process differ fundamentally.
What does the "E3/TR7" suffix indicate in 1PMT5936AE3/TR7?
The "E3" denotes ±5% Zener voltage tolerance and "TR7" specifies EIA-481 compliant 7-inch tape-and-reel packaging containing 3,000 units. This packaging format ensures compatibility with standard pick-and-place equipment and supports high-volume automated assembly without manual handling.
Is 1PMT5936AE3/TR7 suitable for automotive under-hood applications?
Yes-the 1PMT5936AE3/TR7 is qualified for operation from -55°C to +150°C junction temperature and features >16 kV HBM ESD rating, making it suitable for under-hood environments when properly mounted on thermally robust PCBs. Its Powermite® package eliminates flux entrapment risks common in high-reliability automotive SMT processes.
