Product details
Overview
1PMT5953B/TR13 from Microsemi is a 150 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 600 Ω dynamic impedance at 2.5 mA test current and 16.5 mA maximum Zener current. It serves as a precision voltage reference or overvoltage clamp in industrial power supplies and automotive control modules.
For engineers reviewing the 1PMT5953B/TR13 datasheet, 1PMT5953B/TR13 pinout, 1PMT5953B/TR13 application, or 1PMT5953B/TR13 equivalent, key selection criteria include its 150 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heat sinking, low reverse leakage (≤1 µA at 114 V), ESD rating >16 kV HBM, and DO-216 mechanical outline compatibility with automated SMT placement.
Technical Context
This device operates as a two-terminal voltage-regulating diode with cathode designated by TAB 1. Its Zener breakdown is specified at 2.5 mA (IZT) with 600 Ω dynamic impedance (ZZT), and it maintains regulation down to 0.25 mA knee current (IZK) where impedance rises to 6000 Ω.
The Powermite® package integrates a full metallic bottom and locking tab for direct thermal conduction to PCB copper, achieving 30°C/W junction-to-TAB thermal resistance. It supports reflow and wave soldering per EIA-481 tape-and-reel packaging (7" reel, 3,000 pcs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 150 V ±5% at IZT = 2.5 mA - defines stable clamping threshold under nominal bias |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-energy transient suppression without external heatsink |
| Dynamic Impedance | 600 Ω at IZT = 2.5 mA - determines voltage deviation under load current changes |
| Knee Current | 0.25 mA at VZ = 114 V - minimum current to maintain regulation near breakdown |
| Reverse Leakage | ≤1 µA at VR = 114 V - ensures low standby power loss in high-impedance bias networks |
| ESD Rating | >16 kV HBM - provides robust handling during board assembly and field operation |
| Thermal Resistance | 30°C/W junction-to-TAB - allows direct thermal path to PCB copper pour for sustained power handling |
Pinout & Package
Package: Powermite® (DO-216AA), molded surface-mount package with full metallic bottom and integral locking tab acting as cathode terminal (TAB 1). Cathode is unambiguously marked by TAB 1; anode is the opposite lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and voltage-reference node; must be connected to low-impedance ground or return plane |
| Lead 2 | Anode | Current entry point during reverse-bias operation; connects to protected node or voltage source |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and eliminates flux entrapment via full metallic bottom |
| Integral heat-sink locking tab | Provides direct thermal conduction path from junction to PCB, reducing thermal resistance to 30°C/W |
| 16 kV HBM ESD rating | Eliminates need for external ESD protection in harsh-environment control circuits |
| ±5% Zener voltage tolerance | Supports cost-effective voltage clamping where tight regulation is not required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ150A | TVS diode, 150 V standoff, 1500 W peak pulse power, unidirectional | Designed for short-duration surge suppression, not continuous regulation | Select when protecting against lightning or EFT pulses; not suitable for DC voltage reference |
| BZX84-C150 | SOT-23 Zener, 150 V ±5%, 300 mW, no integrated heat sink | Limited to low-power biasing due to 0.3 W rating and higher thermal resistance | Select only for signal-level references; cannot replace 1PMT5953B/TR13 in 3 W power-clamp roles |
Compared with SMCJ150A and BZX84-C150, the 1PMT5953B/TR13 uniquely combines 3.0 W continuous dissipation, DO-216 mechanical compatibility, and 30°C/W thermal resistance-making it the only option among the three capable of sustained voltage regulation in high-power industrial clamping circuits.

FAQ
What is the Zener voltage tolerance for 1PMT5953B/TR13?
The 1PMT5953B/TR13 has a standard Zener voltage tolerance of ±5% at 150 V nominal, measured at 2.5 mA test current and TAB 1 temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, but the base 1PMT5953B/TR13 part uses ±5%.
How is thermal management handled in the 1PMT5953B/TR13 package?
The 1PMT5953B/TR13 uses the Powermite® package with a full metallic bottom and integral locking tab (TAB 1) that acts as both cathode and primary thermal path. Its junction-to-TAB thermal resistance is 30°C/W, enabling direct conduction to PCB copper for reliable 3.0 W operation without external heatsinks.
What is the maximum reverse leakage current for 1PMT5953B/TR13?
The maximum reverse leakage current for 1PMT5953B/TR13 is 1 µA at a reverse voltage of 114 V (76% of nominal 150 V), as specified in the electrical characteristics table. This low leakage supports stable biasing in high-impedance reference networks.
Is 1PMT5953B/TR13 compatible with automated SMT assembly?
Yes, 1PMT5953B/TR13 is fully compatible with automated insertion equipment. Its Powermite® package features a unique locking tab and flat profile designed for pick-and-place accuracy, and it ships in EIA-481-compliant tape-and-reel format (7-inch reel, 3,000 pieces).
What does the "TR13" suffix indicate in 1PMT5953B/TR13?
The "TR13" suffix in 1PMT5953B/TR13 denotes tape-and-reel packaging per EIA-481 standard, specifically indicating a 13-inch reel configuration holding 12,000 units. This differs from the "TR" variant (7-inch reel, 3,000 units) and confirms full traceability and SMT readiness.
