Product details
Overview
1PMT5952AE3/TR7 from Microsemi is a 130 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 450 Ω dynamic impedance at 2.9 mA test current and thermal resistance of 30°C/W junction-to-TAB1 - used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the 1PMT5952AE3/TR7 datasheet, 1PMT5952AE3/TR7 pinout, 1PMT5952AE3/TR7 application, or 1PMT5952AE3/TR7 equivalent, key selection criteria include zener voltage tolerance, power derating at elevated tab temperature, knee current (IZK = 0.25 mA), reverse leakage (IR ≤ 1 µA at VR = 100 V), and ESD robustness (>16 kV HBM).
Technical Context
This device operates as a voltage-reference and clamping element in low-to-medium-power analog and power-supply circuits. Its DO-216 molded package features a full metallic bottom and integral heat-sink locking tab (TAB 1), enabling direct thermal coupling to PCB copper and eliminating solder flux entrapment during reflow.
The 1PMT5952AE3/TR7 exhibits tight voltage regulation across its operating range: zener voltage is specified at IZT = 2.9 mA with VZ = 130 V ±5%, ZZT = 450 Ω, and ZZK = 2000 Ω at IZK = 0.25 mA - confirming stable breakdown behavior even near knee region.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 130 V ±5% at IZT = 2.9 mA - defines precise clamping threshold for overvoltage protection circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling under controlled thermal mounting |
| Dynamic Impedance (ZZT) | 450 Ω at IZT = 2.9 mA - indicates voltage stability under small-signal AC load variations |
| Knee Current (IZK) | 0.25 mA - minimum current required to initiate stable zener conduction; critical for low-current biasing |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies thermal path efficiency when TAB 1 is soldered to thermal pad |
| ESD Rating | >16 kV per Human Body Model - ensures robustness against handling and board-level electrostatic discharge |
| Reverse Leakage | ≤1 µA at VR = 100 V - guarantees minimal standby current in high-impedance sensing or reference paths |
Pinout & Package
Package: Powermite® (DO-216), surface-mount molded case with full metallic bottom and integral heat-sink locking tab. Cathode is designated by TAB 1; anode is the opposite terminal. Mounting orientation is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sink interface and voltage reference node; must be connected to ground or low-impedance return path |
| Opposite Terminal | Anode | Current entry point during reverse-bias operation; connects to regulated rail or transient source |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow assembly while delivering 3.0 W power handling in footprint smaller than DO-41 |
| Integral heat-sink locking tab | TAB 1 provides mechanical anchoring and direct thermal conduction path to PCB copper, reducing junction temperature rise |
| Full metallic bottom | Eliminates solder flux entrapment risk during reflow, improving long-term reliability and void-free solder joints |
| ESD robustness | >16 kV HBM rating supports handling in non-ESD-controlled environments without additional protection circuitry |
| Tight voltage tolerance option | ±5% standard; ±2% (suffix C) and ±1% (suffix D) available for high-precision 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 |
|---|---|---|---|
| 1N5375B | Same 130 V nominal, but DO-41 through-hole package; 5 W rating; higher thermal resistance (~65°C/W) | Requires manual or wave soldering; unsuitable for high-density SMT layouts | Select only if legacy through-hole design or higher power margin is needed without thermal pad integration |
| BZX84-C130 | 130 V ±5%, SOT-23 package; 300 mW rating; no metallic thermal tab; ZZT ≈ 500 Ω | Limited to low-power biasing; cannot handle sustained 3.0 W dissipation | Choose only for space-constrained low-current reference use - not for clamping or regulation at >100 mA |
Compared with 1N5375B and BZX84-C130, the 1PMT5952AE3/TR7 uniquely combines SMT compatibility, 3.0 W power handling, and low thermal resistance via TAB 1 - making it the only viable choice for thermally demanding, high-reliability surface-mount voltage regulation.

FAQ
What is the zener voltage tolerance for 1PMT5952AE3/TR7?
The 1PMT5952AE3/TR7 has a standard zener voltage tolerance of ±5% at 130 V, measured at IZT = 2.9 mA with TAB 1 held at 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request. This tolerance directly impacts regulation accuracy in feedback networks and clamping thresholds in protection circuits.
How is thermal performance defined for 1PMT5952AE3/TR7?
Thermal performance of the 1PMT5952AE3/TR7 is defined by a junction-to-TAB1 thermal resistance of 30°C/W. Since TAB 1 is the cathode and primary heat-sink interface, effective PCB copper area under TAB 1 determines actual junction temperature rise. Derating begins above 60°C tab temperature, per the 3.0 W maximum dissipation rating.
Can 1PMT5952AE3/TR7 be used in automotive applications?
Yes, the 1PMT5952AE3/TR7 is qualified for automotive use: it operates across -55°C to +150°C junction temperature, withstands >16 kV ESD (HBM), and features a flux-free metallic bottom ideal for reflow reliability. Its 130 V clamping capability protects LIN, CAN, and sensor supply lines from load-dump transients when properly mounted with thermal relief.
What does the "E3/TR7" suffix indicate in 1PMT5952AE3/TR7?
The "E3/TR7" suffix denotes tape-and-reel packaging per EIA-481 standard, with 3,000 pieces per 7-inch reel. "E3" specifies the carrier tape configuration and orientation; "TR7" confirms reel size and count. This format ensures compatibility with high-speed pick-and-place equipment and supports automated SMT assembly without manual handling.
Is 1PMT5952AE3/TR7 RoHS compliant?
Yes, the 1PMT5952AE3/TR7 is RoHS compliant and lead-free, consistent with Microsemi's transition to environmentally compliant manufacturing after 2006. The Powermite® package uses matte tin-plated terminals and halogen-free molding compound, meeting JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements.
