Product details
Overview
1PMT5936B/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 750 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 1PMT5936B/TR7 datasheet, 1PMT5936B/TR7 pinout, 1PMT5936B/TR7 application, or 1PMT5936B/TR7 equivalent, key selection criteria include its 30 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heatsinking, DO-216 mechanical outline, and ESD rating >16 kV HBM - all critical for ruggedized, high-reliability power management designs.
Technical Context
This Zener diode operates in reverse breakdown mode to regulate or clamp voltage with tight voltage tolerance and low dynamic impedance. Its Powermite® package integrates a full metallic bottom (TAB 1) for solder-flux-free assembly and a locking tab that functions as an integral heatsink, directly lowering junction-to-tab thermal resistance to 30°C/W.
The device is characterized at TL = 30°C with IZT = 12.5 mA, VZ = 30 V, ZZT = 28 Ω, IZK = 0.25 mA, and IR ≤ 750 µA at VR = 22.8 V. It supports automatic insertion equipment and conforms to EIA-481 tape-and-reel packaging (7″ reel, 3,000 pcs).
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 - enables higher continuous power than standard SOD-123 devices |
| Dynamic Impedance (ZZT) | 28 Ω at 12.5 mA - ensures minimal output voltage variation under load transients |
| Reverse Leakage (IR) | ≤750 µA at VR = 22.8 V - guarantees low quiescent current in standby clamping circuits |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows direct thermal coupling to PCB copper for passive cooling |
| ESD Rating | >16 kV per HBM - provides robust handling in automated manufacturing and field-deployed systems |

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, 3 W rating but in DO-41 through-hole package; no metallic tab or integrated heatsink | Requires PCB via thermal relief or external heatsink; unsuitable for dense SMT layouts | Select only if through-hole assembly is mandated and thermal budget permits higher RθJA |
| Vishay 1N5357B | 30 V, 5 W rating in DO-41; higher power but larger footprint and no SMT compatibility | Used in legacy power supplies where board space and automation are not constraints | Choose when >3 W headroom is required and reflow process is unavailable |
Compared with 1N5936B and 1N5357B, the 1PMT5936B/TR7 delivers superior thermal performance in SMT form factor due to its metallic-tab heatsink and 30°C/W RθJ-TAB, enabling compact, high-power-density designs without layout compromise.

FAQ
What is the Zener voltage tolerance for 1PMT5936B/TR7?
The 1PMT5936B/TR7 has a standard Zener voltage tolerance of ±5% at 30 V, measured at IZT = 12.5 mA and TAB 1 temperature of 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request, but the base 1PMT5936B/TR7 shipped by default carries the ±5% specification.
How is thermal management handled in the 1PMT5936B/TR7 package?
The 1PMT5936B/TR7 uses a Powermite® package with a full metallic bottom (TAB 1) acting as both cathode and primary thermal path. Its specified junction-to-TAB thermal resistance is 30°C/W, allowing direct conduction of heat into PCB copper planes - eliminating need for external heatsinks in most 3 W applications.
Is the 1PMT5936B/TR7 compatible with standard SMT reflow processes?
Yes, the 1PMT5936B/TR7 is qualified for standard lead-free reflow profiles. Its molded Powermite® package and metallic tab prevent flux entrapment, and its -55°C to +150°C junction/storage temperature range supports IPC/JEDEC Class 3 reliability requirements in industrial and automotive applications.
What does the "TR7" suffix indicate in 1PMT5936B/TR7?
The "TR7" suffix denotes tape-and-reel packaging per EIA-481 standard on a 7-inch reel containing 3,000 units. This format is optimized for high-speed pick-and-place equipment and ensures consistent feeding and placement accuracy during automated assembly.
Can the 1PMT5936B/TR7 be used as a substitute for through-hole Zeners like 1N5936B?
The 1PMT5936B/TR7 shares identical electrical specs (30 V, 3 W) with the through-hole 1N5936B but differs mechanically: it uses DO-216AA surface-mount packaging with integrated heatsinking. Substitution requires PCB redesign for SMT pads and thermal land pattern - it is not a drop-in replacement, though functionally equivalent in regulated voltage performance.
