Product details
Overview
1PMT5926BE3/TR7 from Microsemi is a 11 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 5.5 Ω dynamic impedance at 34.1 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5926BE3/TR7 datasheet, 1PMT5926BE3/TR7 pinout, 1PMT5926BE3/TR7 application, or 1PMT5926BE3/TR7 equivalent, key selection criteria include Zener voltage tolerance, power derating above 60°C, knee current (0.25 mA), reverse leakage (1 µA max at 8.4 V), and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and mechanical stability during reflow or wave soldering.
The device exhibits low dynamic impedance (5.5 Ω) and low knee impedance (550 Ω), enabling stable regulation even under light-load conditions. Reverse leakage remains ≤1 µA up to 8.4 V, supporting low-power standby circuit integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 11 V ±5% at 34.1 mA - defines nominal regulation point with predictable deviation in production |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power before thermal shutdown or degradation |
| Dynamic Impedance | 5.5 Ω at IZT = 34.1 mA - determines output voltage variation under load current changes |
| Knee Current | 0.25 mA - minimum current needed to enter useful regulation region; critical for low-power bias networks |
| Reverse Leakage | ≤1 µA at VR = 8.4 V - ensures minimal quiescent current draw in high-impedance sensing or standby circuits |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables thermal design using TAB1 as primary heat path to PCB copper |
| ESD Rating | >16 kV HBM - supports handling without special ESD controls in standard assembly environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4740A | DO-41 through-hole package; 10 V ±5%; 1.0 W rating; higher thermal resistance (~100°C/W) | Requires manual or wave-solder assembly; unsuitable for high-density SMT layouts or 3 W dissipation needs | Select only if legacy through-hole design or lower power (<1 W) operation is acceptable |
| BZX84-C11 | SOT-23 package; 11 V ±5%; 300 mW rating; 250 Ω dynamic impedance; no metallic thermal tab | Limited to low-power signal-level clamping; cannot sustain 34.1 mA continuous without derating | Choose for space-constrained logic-level protection where 3 W capability is unnecessary |
Compared with 1N4740A and BZX84-C11, the 1PMT5926BE3/TR7 uniquely combines SMT compatibility, 3.0 W power handling, and low-impedance regulation in a thermally optimized package-making it the only option among the three suitable for high-current, high-reliability power rail clamping.

FAQ
What is the Zener voltage tolerance for 1PMT5926BE3/TR7?
The 1PMT5926BE3/TR7 has a nominal Zener voltage of 11 V with a standard tolerance of ±5%, as confirmed in the MSC0995 datasheet. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, but the base part number 1PMT5926BE3/TR7 uses the ±5% grade. This tolerance applies at 34.1 mA test current and TAB 1 temperature of 30°C.
Can 1PMT5926BE3/TR7 be used in place of a 1N4740A?
No, 1PMT5926BE3/TR7 is not a direct replacement for 1N4740A due to differences in package (Powermite® vs. DO-41), power rating (3.0 W vs. 1.0 W), and thermal performance (30°C/W vs. ~100°C/W). While both regulate near 11 V, substituting 1PMT5926BE3/TR7 into a 1N4740A footprint requires PCB redesign and thermal validation. The 1PMT5926BE3/TR7 is intended for higher-power SMT applications.
What is the maximum reverse voltage that can be applied to 1PMT5926BE3/TR7 without significant leakage?
The 1PMT5926BE3/TR7 specifies a maximum reverse current of 1 µA at 8.4 V (VR), meaning it maintains low leakage up to this voltage. Beyond 8.4 V, current rises sharply toward the Zener breakdown region. For reliable non-conducting behavior, keep reverse bias below 8.4 V; operation above this level engages regulation and must account for power dissipation limits.
How is thermal management handled for 1PMT5926BE3/TR7 in high-power operation?
Thermal management for 1PMT5926BE3/TR7 relies on TAB 1 as the primary thermal path. With a junction-to-TAB1 thermal resistance of 30°C/W, the device requires a well-coppered PCB pad connected to TAB 1 to dissipate 3.0 W at 60°C ambient. Derating is necessary above 60°C - e.g., at 100°C TAB temperature, maximum allowable power drops to ~1.8 W per linear derating rule.
Is 1PMT5926BE3/TR7 compatible with lead-free reflow profiles?
Yes, 1PMT5926BE3/TR7 is qualified for lead-free reflow processing per J-STD-020. Its Powermite® package withstands peak temperatures up to 260°C for 10 seconds, consistent with standard Pb-free soldering requirements. The full metallic bottom also promotes uniform heating and minimizes warpage risk during reflow.
