Product details
Overview
1PMT5953CE3/TR13 from Microsemi is a 150 V, ±5% tolerance Zener diode in the Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 600 Ω dynamic impedance at 2.5 mA test current and 16 kV HBM ESD rating. It serves as a precision voltage reference or overvoltage clamp in industrial power supply feedback loops and transient protection circuits.
For engineers reviewing the 1PMT5953CE3/TR13 datasheet, 1PMT5953CE3/TR13 pinout, 1PMT5953CE3/TR13 application, or 1PMT5953CE3/TR13 equivalent, key selection criteria include its 150 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heatsinking, low reverse leakage (≤1 µA at 120 V), and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This device operates as a two-terminal voltage-regulating diode with sharp Zener breakdown at 150 V under 2.5 mA test current. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction from junction to PCB pad, enabling stable 3.0 W operation without external heatsinks.
The 1PMT5953CE3/TR13 exhibits 600 Ω dynamic impedance at IZT and ≤1 µA reverse leakage at VR = 120 V, supporting stable regulation in high-impedance bias networks. Its 30°C/W junction-to-TAB thermal resistance and -55°C to +150°C operating range suit harsh-environment industrial and telecom power systems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5953B | Same 150 V VZ and ±5% tolerance, but in DO-41 through-hole package; no metallic tab or integrated heatsink | Requires PCB footprint change and lacks Powermite® thermal performance; suitable only where manual assembly or legacy layout constraints apply | Select 1PMT5953CE3/TR13 for SMT volume production requiring thermal efficiency and automated placement |
| SMBJ150A | 150 V unidirectional TVS diode; higher peak pulse power (600 W), but looser voltage tolerance (±5% VBR at IT = 1 mA) and no regulated Zener knee | Designed for transient suppression, not precision regulation; unsuitable for feedback references due to soft breakdown characteristic | Choose 1PMT5953CE3/TR13 when stable DC voltage reference or clamping with tight VZ is required |
Compared with 1N5953B and SMBJ150A, the 1PMT5953CE3/TR13 uniquely combines precision Zener regulation, SMT manufacturability, and enhanced thermal performance via its metallic-tab Powermite® package-making it optimal for space-constrained, thermally demanding DC voltage reference and clamping roles.

FAQ
What is the Zener voltage tolerance for 1PMT5953CE3/TR13?
The 1PMT5953CE3/TR13 has a standard Zener voltage tolerance of ±5% at 150 V, as specified in the MSC0995 datasheet. This tolerance applies under test conditions of IZT = 2.5 mA and TAB temperature = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the CE3 variant denotes the standard ±5% grade.
How is thermal management handled in the 1PMT5953CE3/TR13 package?
The 1PMT5953CE3/TR13 uses Microsemi's Powermite® package with a full metallic bottom and integral locking tab that serves as both mechanical anchor and primary thermal path. Its 30°C/W junction-to-TAB thermal resistance requires direct soldering of TAB 1 to a large copper pour for effective heat dissipation, enabling full 3.0 W operation without external heatsinks.
Is the 1PMT5953CE3/TR13 compatible with lead-free reflow processes?
Yes, the 1PMT5953CE3/TR13 is qualified for lead-free reflow soldering per J-STD-020. Its molded Powermite® package and metallic terminals withstand peak temperatures up to 260°C. The device's -55°C to +150°C storage and operating temperature range ensures reliability across standard Pb-free thermal profiles used in modern SMT lines.
What does the 'TR13' suffix indicate in 1PMT5953CE3/TR13?
The 'TR13' suffix denotes tape-and-reel packaging per EIA-481 standard on a 13-inch reel containing 12,000 units. This format is optimized for high-volume automated placement equipment. The 'CE3' portion specifies the ±5% Zener voltage tolerance and standard electrical grade, distinguishing it from tighter-tolerance variants like CE2 (±2%) or CED (±1%).
Can the 1PMT5953CE3/TR13 be used as a replacement for through-hole Zeners like 1N5953B?
The 1PMT5953CE3/TR13 shares identical electrical specifications (150 V, ±5%, 3.0 W) with the 1N5953B but differs mechanically: it uses a surface-mount Powermite® package with TAB 1 cathode instead of DO-41 axial leads. Direct replacement requires PCB redesign to accommodate the SMT footprint and thermal pad layout-no pin-to-pin compatibility exists.
