Product details
Overview
1PMT5926A/TR7 from Microsemi is a 11 V, 3.0 W surface-mount Zener diode in the Powermite® package (DO-216), featuring 5.5 Ω dynamic impedance at 34.1 mA test current, 8.4 mA maximum zener current, and thermal resistance of 30°C/W junction-to-tab. It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5926A/TR7 datasheet, 1PMT5926A/TR7 pinout, 1PMT5926A/TR7 application, or 1PMT5926A/TR7 equivalent, key selection criteria include zener voltage tolerance (±5%), ESD rating (>16 kV HBM), low reverse leakage (1 µA max at 1 V), full metallic bottom for flux-free assembly, and compatibility with automated insertion equipment.
Technical Context
This Zener diode operates with a nominal zener voltage of 11 V at 34.1 mA test current (IZT), exhibiting tight regulation via low dynamic impedance (5.5 Ω) and controlled knee behavior (IZK = 0.25 mA, ZZK = 550 Ω). Its DO-216 Powermite® package integrates a locking tab that functions as both mechanical anchor and thermal path to PCB copper.
The device sustains continuous power dissipation of 3.0 W when tab temperature (TL) is held at 60°C, with junction-to-tab thermal resistance of 30°C/W. Reverse leakage remains ≤1 µA at VR = 1 V, and forward voltage is 1.2 V at 200 mA - confirming robust conduction capability for bidirectional protection schemes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V ±5% at IZT = 34.1 mA - sets stable reference point for feedback or clamping circuits |
| Power Dissipation | 3.0 W at TL = 60°C - enables high-energy transient suppression without external heatsink |
| Dynamic Impedance (ZZT) | 5.5 Ω at IZT - ensures minimal voltage shift under load current variation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5926B | Same 11 V/3 W specification but in DO-41 through-hole package; no metallic tab or flux-free bottom | Requires manual or wave soldering; unsuitable for high-density SMT layouts or automated insertion | Select 1N5926B only if legacy through-hole assembly or higher mechanical ruggedness in non-vibrating environments is required |
| BZX84-C11 | 11 V, 300 mW SOT-23 device; 15 Ω dynamic impedance; 100 nA IR at 8.8 V | Limited to low-power signal-level clamping; cannot sustain 3 W transients | Choose BZX84-C11 for space-constrained logic-level protection where energy absorption is <0.1 J |
Compared with 1PMT5926A/TR7, 1N5926B offers identical electrical specs but lacks SMT optimization and thermal performance, while BZX84-C11 trades power handling for footprint reduction - making 1PMT5926A/TR7 the sole choice for 3 W SMT Zener applications demanding flux-free assembly and tab-cooled operation.

FAQ
What is the zener voltage tolerance for 1PMT5926A/TR7?
The 1PMT5926A/TR7 has a standard zener voltage tolerance of ±5% at 11 V, measured at 34.1 mA test current and tab temperature of 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request. This tolerance directly impacts regulation accuracy in feedback loops and reference circuits using the 1PMT5926A/TR7.
How does the Powermite® package improve thermal performance of 1PMT5926A/TR7?
The Powermite® package of the 1PMT5926A/TR7 features a full metallic bottom and integral locking tab that serve as a low-resistance thermal path from junction to PCB copper. With a specified thermal resistance of 30°C/W junction-to-tab, the 1PMT5926A/TR7 achieves effective passive cooling without additional heatsinks - critical for sustaining its 3.0 W power rating in compact layouts.
Is 1PMT5926A/TR7 compatible with automated pick-and-place equipment?
Yes, the 1PMT5926A/TR7 is explicitly designed for compatibility with automatic insertion equipment. Its Powermite® package includes a unique locking tab that secures placement during handling and reflow, and its standardized tape-and-reel packaging (EIA-481, 7-inch reel with 3,000 units) ensures reliable feeding in high-speed SMT lines using the 1PMT5926A/TR7.
What is the maximum reverse leakage current for 1PMT5926A/TR7?
The maximum reverse leakage current (IR) for the 1PMT5926A/TR7 is 1 µA at a reverse voltage (VR) of 1 V and ambient temperature of 30°C. This low leakage supports precision biasing and sensing applications where current draw must remain below microampere thresholds - a key design parameter confirmed in the official Microsemi MSC0995 datasheet for the 1PMT5926A/TR7.
Can 1PMT5926A/TR7 be used in automotive under-hood applications?
Yes, the 1PMT5926A/TR7 is rated for junction and storage temperatures from -55°C to +150°C, meeting under-hood thermal requirements. Its 3.0 W power handling, >16 kV HBM ESD rating, and flux-free metallic bottom make the 1PMT5926A/TR7 suitable for engine control modules, transmission controllers, and other automotive electronics exposed to high temperature and mechanical stress.
