Product details
Overview
1PMT5936/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 thermal resistance of 30°C/W junction-to-TAB. It serves as a precision voltage reference or overvoltage clamp in power supply regulation and transient protection circuits.
For engineers reviewing the 1PMT5936/TR7 datasheet, 1PMT5936/TR7 pinout, 1PMT5936/TR7 application, or 1PMT5936/TR7 equivalent, key selection criteria include its 30 V nominal Zener voltage, 3.0 W power handling in a DO-216 outline, ESD rating >16 kV HBM, low reverse leakage (≤1 µA at 22.8 V), and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load or line conditions. Its Powermite® package features a full metallic bottom and integral heat-sink locking tab, enabling efficient thermal conduction from junction to PCB via TAB 1 - the cathode terminal - with measured thermal resistance of 30°C/W.
The device exhibits tight knee characteristics (IZK = 0.25 mA, ZZK = 750 Ω) and low dynamic impedance (ZZT = 28 Ω at IZT = 12.5 mA), supporting stable regulation even near minimum operating current. Reverse leakage remains ≤1 µA up to VR = 22.8 V, ensuring minimal standby power loss in clamping or reference applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor 1N5936B | Same 30 V, ±5%, DO-204AL (DO-41) through-hole package; 1.0 W rating; no metallic tab or integrated heatsink | Requires PCB footprint redesign and lacks thermal performance for >1 W continuous clamping | Select when legacy through-hole assembly is mandated and power demand ≤1.0 W |
| Vishay 1N5355B | 30 V, ±5%, DO-204AL package; 5.0 W rating but higher ZZT (40 Ω); thermal resistance ~50°C/W junction-to-case | Better power margin but inferior thermal coupling and less stable regulation at low currents | Select when peak pulse power >3 W is required and board space allows larger footprint |
Compared with 1PMT5936/TR7, the 1N5936B offers identical voltage specs but lacks surface-mount compatibility and thermal efficiency, while the 1N5355B trades tighter regulation and superior thermal design for higher peak power - making 1PMT5936/TR7 optimal for space-constrained, thermally demanding SMT applications requiring stable 30 V reference or clamping.

FAQ
What is the Zener voltage tolerance for 1PMT5936/TR7?
The 1PMT5936/TR7 has a standard Zener voltage tolerance of ±5% at 30 V nominal, measured at IZT = 12.5 mA and TAB temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the /TR7 variant ships with standard ±5% tolerance.
How is thermal management handled in the 1PMT5936/TR7 package?
The 1PMT5936/TR7 uses the Powermite® package with TAB 1 as the cathode and primary thermal interface. Its 30°C/W junction-to-TAB thermal resistance requires soldering TAB 1 to a sufficient copper area on the PCB to achieve the full 3.0 W power rating at 60°C tab temperature - no external heatsink is needed if layout guidelines are followed.
Is the 1PMT5936/TR7 compatible with lead-free reflow processes?
Yes, the 1PMT5936/TR7 is qualified for standard lead-free reflow profiles, including JEDEC J-STD-020-compliant peak temperatures up to 260°C. Its molded Powermite® package and metallic bottom are designed to withstand thermal cycling without delamination or solder joint integrity loss.
What does the "/TR7" suffix indicate for 1PMT5936/TR7?
The "/TR7" suffix denotes tape-and-reel packaging per EIA-481 standard, with 3,000 units per 7-inch reel. This format is optimized for high-speed pick-and-place equipment and ensures consistent orientation (cathode TAB 1 leading) for automated assembly of the 1PMT5936/TR7.
Can 1PMT5936/TR7 be used as a bidirectional ESD protector?
While primarily designed as a unidirectional Zener, the 1PMT5936/TR7 conducts in forward bias (~1.2 V @ 200 mA) and reverse breakdown (30 V), enabling basic bidirectional clamping. However, dedicated TVS diodes offer lower clamping voltage and faster response - use 1PMT5936/TR7 only where moderate ESD immunity (>16 kV HBM) and voltage reference function are jointly required.
