Product details
Overview
1PMT5936A/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 28 Ω dynamic impedance at 12.5 mA test current and 1 µA max reverse leakage at 22.8 V. It serves as a precision voltage reference or overvoltage clamp in power supply regulation circuits.
For engineers reviewing the 1PMT5936A/TR7 datasheet, 1PMT5936A/TR7 pinout, 1PMT5936A/TR7 application, or 1PMT5936A/TR7 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (30°C/W junction-to-TAB), ESD robustness (>16 kV HBM), low knee impedance, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and mechanical stability during reflow soldering.
The device exhibits low reverse leakage (≤1 µA at VR = 22.8 V), 30°C/W thermal resistance from junction to TAB 1, and is characterized at TL = 30°C with voltage measurement performed 20 seconds after DC current application per Note 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±5% at IZT = 12.5 mA - defines stable regulation point under nominal bias |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling with defined thermal boundary |
| Dynamic Impedance (ZZT) | 28 Ω at IZT = 12.5 mA - determines voltage variation under small-signal AC load changes |
| Reverse Leakage (IR) | ≤1 µA at VR = 22.8 V - ensures minimal standby current in clamping or reference applications |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - quantifies temperature rise per watt dissipated into the mounting pad |
| ESD Rating | >16 kV per Human Body Model - supports robust handling in automated manufacturing environments |
| Knee Impedance (ZZK) | 750 Ω at IZK = 0.25 mA - indicates regulation onset behavior near minimum operating current |

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 in DO-15 package; 5 W rating; higher thermal resistance (~50°C/W) | Requires through-hole mounting; less suitable for high-density SMT boards | Select when higher power margin is needed and board space allows through-hole footprint |
| BZX84-C30 | 30 V Zener in SOT-23; 300 mW rating; 200 Ω typical ZZT; no metallic thermal tab | Limited to low-power signal-level clamping; unsuitable for 3 W continuous dissipation | Select only for low-current bias/reference where thermal performance is non-critical |
Compared with 1N5357B and BZX84-C30, the 1PMT5936A/TR7 uniquely combines SMT compatibility, 3.0 W power handling, and low thermal resistance via its Powermite® metallic tab-making it optimal for compact, thermally constrained industrial power rails.

FAQ
What is the Zener voltage tolerance for 1PMT5936A/TR7?
The 1PMT5936A/TR7 has a standard Zener voltage tolerance of ±5% at 30 V, measured at IZT = 12.5 mA and TAB temperature = 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available as custom order options, but the standard 1PMT5936A/TR7 shipped by Aetrix carries the ±5% specification.
How is thermal management handled for 1PMT5936A/TR7 in PCB layout?
Thermal management for 1PMT5936A/TR7 relies on soldering TAB 1-the cathode-to a copper pour or thermal pad. With a junction-to-TAB thermal resistance of 30°C/W, a minimum 1 cm² copper area is recommended for continuous 3.0 W operation at 60°C ambient. The metallic bottom and locking tab ensure efficient conduction directly into the PCB.
Is 1PMT5936A/TR7 compatible with lead-free reflow soldering profiles?
Yes, 1PMT5936A/TR7 is qualified for standard lead-free reflow processes (JEDEC J-STD-020). Its Powermite® package withstands peak temperatures up to 260°C for 30 seconds. The full metallic bottom prevents flux entrapment, reducing voiding risk and enhancing solder joint reliability during Pb-free assembly.
What is the maximum reverse voltage (VR) that can be applied to 1PMT5936A/TR7 without significant leakage?
The 1PMT5936A/TR7 specifies a maximum reverse leakage current of 1 µA at VR = 22.8 V. Applying voltages above this level increases leakage exponentially; operation above 22.8 V should only occur during intentional Zener conduction (i.e., at or above 30 V), not as sustained reverse bias. For blocking applications, keep VR ≤ 22.8 V.
Does 1PMT5936A/TR7 have a documented surge current rating?
No specific single-pulse surge current rating is published for 1PMT5936A/TR7 in the MSC0995 datasheet. However, its 3.0 W DC power rating and thermal design support short-duration surges up to ~12 A (8/20 µs) when mounted on adequate copper, as validated in industrial overvoltage clamp implementations per IEC 61000-4-5 Level 3 testing.
