Product details
Overview
1PMT5936BE3/TR13 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 temperature of 60°C, with 12.5 mA test current, 28 Ω dynamic impedance, and 1 µA max reverse leakage at 22.8 V. It serves as a precision voltage reference or overvoltage clamp in power supply regulation and transient protection circuits.
For engineers reviewing the 1PMT5936BE3/TR13 datasheet, 1PMT5936BE3/TR13 pinout, 1PMT5936BE3/TR13 application, or 1PMT5936BE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance (750 Ω at 0.25 mA), and compatibility with EIA-481 tape-and-reel automated 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 eliminate solder flux entrapment during reflow.
The device exhibits low reverse leakage (≤1 µA at VR = 22.8 V), stable dynamic impedance (28 Ω at IZT = 12.5 mA), and a thermal resistance of 30°C/W from junction to TAB 1 - enabling reliable operation up to +150°C storage and junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±5% at 12.5 mA - defines nominal regulation point with production-grade tolerance |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling under defined thermal condition |
| Dynamic Impedance (ZZT) | 28 Ω at 12.5 mA - indicates small-signal AC resistance affecting regulation stability under load variation |
| Reverse Leakage (IR) | ≤1 µA at 22.8 V - ensures minimal standby current in clamping or reference applications |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - quantifies thermal path efficiency for PCB heat sinking via metal tab |
| ESD Rating | >16 kV per HBM - supports robust handling in automated manufacturing without additional ESD protection |
| Knee Impedance (ZZK) | 750 Ω at 0.25 mA - characterizes voltage regulation onset 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 |
|---|---|---|---|
| 1N5936B | Same 30 V Zener voltage, but in DO-41 through-hole package; no metallic tab or integrated heat sink | Lacks thermal performance and SMT compatibility; requires manual or wave soldering | Choose only if legacy through-hole design or thermal requirements are less stringent |
| BZX84-C30 | 30 V Zener in SOT-23; 350 mW rating, higher dynamic impedance (90 Ω), lower ESD rating (8 kV HBM) | Suitable for low-power signal references, not for 3 W clamping or high-current regulation | Select when space-constrained PCBs demand SOT-23 footprint and power needs are ≤350 mW |
Compared with 1N5936B and BZX84-C30, the 1PMT5936BE3/TR13 uniquely combines 3.0 W power handling, SMT compatibility, and 30°C/W thermal resistance in a single surface-mount package - making it optimal for high-reliability, thermally demanding Zener applications where both power and manufacturability matter.

FAQ
What is the Zener voltage tolerance for 1PMT5936BE3/TR13?
The 1PMT5936BE3/TR13 has a standard Zener voltage tolerance of ±5% at 30 V, measured at 12.5 mA test current and TAB 1 temperature of 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the E3/TR13 variant uses the standard ±5% grade.
How is thermal management implemented in the 1PMT5936BE3/TR13 package?
The 1PMT5936BE3/TR13 uses the Powermite® package with a full metallic bottom and integral locking tab (TAB 1) that serves as both cathode and primary thermal interface. Its specified thermal resistance of 30°C/W junction-to-TAB enables effective heat transfer to the PCB copper pour when TAB 1 is properly soldered to a thermal pad.
Can 1PMT5936BE3/TR13 be used in place of through-hole Zeners like 1N5936B?
The 1PMT5936BE3/TR13 provides identical 30 V Zener voltage and comparable electrical specs to 1N5936B, but it is not a drop-in replacement due to its DO-216 surface-mount footprint and thermal reliance on TAB 1 soldering. PCB redesign is required to accommodate the Powermite® package and thermal pad layout.
What is the maximum reverse leakage current for 1PMT5936BE3/TR13?
The 1PMT5936BE3/TR13 has a maximum reverse leakage current of 1 µA at a reverse voltage of 22.8 V, measured at TL = 30°C. This low leakage supports high-impedance reference and sensing applications where parasitic current must be minimized.
Is 1PMT5936BE3/TR13 compatible with standard SMT assembly processes?
Yes, the 1PMT5936BE3/TR13 is supplied in EIA-481 compliant tape-and-reel format (3,000 pieces per 7-inch reel) and designed for compatibility with automated pick-and-place equipment and reflow soldering profiles. Its Powermite® package geometry and metallic bottom prevent flux entrapment and support consistent placement accuracy.
