Product details
Overview
1PMT5936CE3/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 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 1PMT5936CE3/TR7 datasheet, 1PMT5936CE3/TR7 pinout, 1PMT5936CE3/TR7 application, or 1PMT5936CE3/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.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature 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.
The device exhibits tight voltage regulation with 28 Ω dynamic impedance at 12.5 mA IZT and maintains <1 µA reverse leakage up to 22.8 V, supporting reliable clamping in transient suppression and reference applications where low leakage and predictable knee behavior are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±5% at IZT = 12.5 mA, TL = 30°C - defines nominal regulation point with production-grade tolerance |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous power handling with defined thermal boundary condition |
| Dynamic Impedance (ZZT) | 28 Ω at IZT = 12.5 mA - indicates small-signal AC resistance near regulation point; impacts voltage stability under load variation |
| Reverse Leakage (IR) | <1 µA at VR = 22.8 V - ensures minimal standby current in clamping or reference configurations |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - quantifies thermal path efficiency; enables thermal design using TAB as heatsink |
| ESD Rating | >16 kV per Human Body Model - supports robust handling and operation in electrostatic-sensitive environments |
| Knee Current (IZK) | 0.25 mA - minimum current required to enter useful regulation region; informs low-current biasing design |
Pinout & Package
Package: Powermite® surface-mount molded package with full metallic bottom and integral heat sink locking tab; cathode designated by TAB 1; weight ≈ 0.016 g; mechanical outline conforms to DO-216.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary thermal and electrical connection point; must be soldered to copper pour for thermal management and circuit return |
| Lead 2 | Anode | Signal input terminal; reverse-biased during Zener operation; connects to regulated node or transient source |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables high-density PCB layout while delivering 3.0 W power handling typically found in larger through-hole packages |
| Integral heat sink locking tab | Provides direct thermal path from junction to PCB; reduces thermal resistance to 30°C/W without external heatsink |
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and solder joint integrity |
| ESD robustness | >16 kV HBM rating allows safe handling and integration into unshielded industrial or automotive subsystems |
| Automated insertion compatibility | Standard tape-and-reel packaging (EIA-481) and mechanical symmetry support pick-and-place and AOI inspection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5936BRLG | Same 30 V nominal Zener voltage, but in DO-41 through-hole package; higher thermal resistance (~65°C/W); no metallic heat sink tab | Requires PCB hole drilling and wave soldering; unsuitable for high-density SMT layouts | Select when legacy through-hole assembly or manual prototyping is required |
| BZX84-C30LT1G | 30 V Zener in SOT-23; rated for 300 mW only; 40 Ω ZZT; no specified HBM ESD rating | Limited to low-power signal-level clamping; cannot replace 1PMT5936CE3/TR7 in 3 W power regulation roles | Select only for space-constrained, low-power bias/reference use - not a functional replacement |
Compared with 1N5936BRLG and BZX84-C30LT1G, the 1PMT5936CE3/TR7 uniquely combines 3.0 W SMT power handling, 30°C/W thermal resistance via TAB 1, and >16 kV ESD robustness - making it irreplaceable in high-reliability, thermally demanding industrial and automotive clamping applications.

FAQ
What is the Zener voltage tolerance for 1PMT5936CE3/TR7?
The 1PMT5936CE3/TR7 has a standard Zener voltage tolerance of ±5% at 30 V, measured at 12.5 mA test current and TAB temperature of 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the CE3 suffix denotes the standard ±5% version. This tolerance directly affects regulation accuracy in precision reference applications.
How is thermal management achieved in the 1PMT5936CE3/TR7 package?
Thermal management in the 1PMT5936CE3/TR7 relies on its Powermite® package design: TAB 1 serves as both cathode and primary thermal interface, with a specified junction-to-TAB thermal resistance of 30°C/W. Engineers must connect TAB 1 to an adequately sized copper pour to dissipate up to 3.0 W reliably. The full metallic bottom and locking tab enhance heat transfer without requiring external heatsinks.
Is the 1PMT5936CE3/TR7 suitable for automotive applications?
Yes, the 1PMT5936CE3/TR7 supports automotive use with its -55°C to +150°C junction/storage temperature range, >16 kV HBM ESD rating, and robust Powermite® construction. While not AEC-Q101 certified out-of-box, it is widely deployed in body control modules and powertrain subsystems where its 30 V regulation and 3.0 W clamping capability meet functional safety requirements when validated per system-level testing.
What does the "TR7" suffix indicate in 1PMT5936CE3/TR7?
"TR7" denotes tape-and-reel packaging per EIA Standard 481, with 7-inch reels containing 3,000 units. This format ensures compatibility with high-speed SMT pick-and-place equipment and supports automated manufacturing. The "CE3" portion specifies the ±5% Zener voltage tolerance and 3.0 W power rating per Microsemi's internal coding system.
Can the 1PMT5936CE3/TR7 replace older through-hole Zeners like 1N5936B?
The 1PMT5936CE3/TR7 provides equivalent 30 V Zener functionality but is not a drop-in replacement for 1N5936B due to its surface-mount Powermite® package, different pinout (TAB 1 cathode vs. axial leads), and superior thermal performance (30°C/W vs. ~65°C/W). PCB redesign is required, though the upgrade delivers higher power density, better ESD immunity, and automated assembly readiness.
