Product details
Overview
1PMT5926BE3/TR13 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 1 µA max reverse leakage at 8.4 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5926BE3/TR13 datasheet, 1PMT5926BE3/TR13 pinout, 1PMT5926BE3/TR13 application, or 1PMT5926BE3/TR13 equivalent, key selection criteria include zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance (550 Ω at 0.25 mA), 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 current range. Its Powermite® package features a full metallic bottom and integral heat sink locking tab, enabling direct thermal conduction from the die to PCB copper via TAB 1 - the cathode terminal - with measured thermal resistance of 30°C/W.
The device exhibits low reverse leakage (≤1 µA at VR = 8.4 V) and stable dynamic impedance (5.5 Ω at IZT = 34.1 mA), supporting reliable voltage clamping in transient-suppression circuits and stable reference generation in low-noise analog subsystems where thermal management and ESD robustness (>16 kV HBM) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11.0 V ±5% at IZT = 34.1 mA, TL = 30°C - defines nominal regulation point for voltage reference or clamp design |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power handling with board-level heatsinking |
| Dynamic Impedance (ZZT) | 5.5 Ω at IZT = 34.1 mA - determines voltage deviation under load current variation |
| Reverse Leakage (IR) | ≤1 µA at VR = 8.4 V - ensures minimal standby current in high-impedance bias networks |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - quantifies thermal path efficiency for PCB copper pad cooling |
| ESD Rating | >16 kV per Human Body Model - supports robustness in handling and end-equipment surge environments |
| Knee Impedance (ZZK) | 550 Ω at IZK = 0.25 mA - indicates regulation onset behavior near minimum operating current |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5926BTR | Same 11 V, ±5%, 3.0 W rating but in DO-41 through-hole package; no metallic bottom or locking tab | Requires manual or wave-solder assembly; lacks integrated thermal path to PCB | Select when legacy through-hole layout or higher vibration tolerance is required |
| BZX84-C11LT1G | 11 V, ±5%, 300 mW SOT-23 package; 15 Ω ZZT at 5 mA; 100 nA IR at 8.4 V | Lower power handling limits use to signal-level clamping only; superior leakage for ultra-low-power bias | Select for space-constrained, low-current reference nodes where 3.0 W capability is unnecessary |
Compared with 1PMT5926BE3/TR13, 1N5926BTR offers identical electrical specs but requires PCB redesign for through-hole mounting and delivers inferior thermal performance, while BZX84-C11LT1G trades 10× lower power for 10× lower leakage and smaller footprint - making each suitable only for distinct thermal, power, and assembly constraints.

FAQ
What is the zener voltage tolerance for 1PMT5926BE3/TR13?
The 1PMT5926BE3/TR13 has a standard zener voltage tolerance of ±5% at 11.0 V, measured at 34.1 mA test current with TAB 1 temperature held at 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available as custom order options, but the base 1PMT5926BE3/TR13 part shipped is ±5%.
How is thermal management implemented in the 1PMT5926BE3/TR13 package?
The 1PMT5926BE3/TR13 uses the Powermite® package's full metallic bottom and integral heat sink locking tab to conduct heat directly from the silicon junction to the PCB copper via TAB 1. Its specified thermal resistance is 30°C/W junction-to-TAB, meaning a 3.0 W dissipation raises junction temperature by 90°C above TAB temperature - so proper copper pad sizing is essential for reliability.
What does the "E3/TR13" suffix indicate in 1PMT5926BE3/TR13?
The "E3" denotes RoHS-compliant, lead-free termination finish per JEDEC J-STD-609, and "TR13" specifies packaging in 13-inch tape-and-reel per EIA-481 standard containing 12,000 units. This distinguishes it from the 7-inch reel variant (TR) and non-RoHS versions, ensuring compliance and automated assembly readiness.
Can 1PMT5926BE3/TR13 be used as a replacement for 1N5926B in existing designs?
No - although both are 11 V, 3.0 W Zener diodes, 1PMT5926BE3/TR13 uses the surface-mount Powermite® (DO-216AA) package with TAB 1 cathode, while 1N5926B is DO-41 through-hole. They are not pin-compatible or drop-in replacements; PCB layout and assembly process must be redesigned to accommodate the 1PMT5926BE3/TR13's thermal pad and SMT requirements.
What is the maximum reverse leakage current for 1PMT5926BE3/TR13 at 8.4 V?
The maximum reverse leakage current for 1PMT5926BE3/TR13 is 1 µA at VR = 8.4 V and TL = 30°C, as specified in the Electrical Characteristics table. This value is critical for low-power bias networks, ensuring minimal current draw in standby or high-impedance sensing paths where leakage could introduce measurable offset errors.
