Product details
Overview
1PMT5927E3/TR13 from Microsemi is a 12 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 6.5 Ω dynamic impedance at 31.2 mA test 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 of industrial control modules.
For engineers reviewing the 1PMT5927E3/TR13 datasheet, 1PMT5927E3/TR13 pinout, 1PMT5927E3/TR13 application, or 1PMT5927E3/TR13 equivalent, key selection criteria include zener voltage tolerance, power derating above 60°C, knee current (0.25 mA), reverse leakage (<1 µA at 9.1 V), and ESD robustness (>16 kV HBM).
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 soldering.
The device exhibits low dynamic impedance (6.5 Ω) and low knee impedance (400 Ω), enabling stable regulation even under light-load conditions. Reverse leakage remains below 1 µA up to 9.1 V, supporting low-power standby circuit integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 12 V ±5% at 31.2 mA - defines regulated output voltage under nominal bias |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling with defined thermal boundary |
| Dynamic Impedance | 6.5 Ω at IZT = 31.2 mA - determines voltage deviation under load current changes |
| Knee Current | 0.25 mA - minimum current needed to enter useful regulation region |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables thermal design using tab as primary heat path |
| ESD Rating | >16 kV per HBM - supports robustness in handling and board-level ESD events |
| Reverse Leakage | <1 µA at VR = 9.1 V - ensures minimal standby current in clamping applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5927B | Same 12 V zener voltage and ±5% tolerance, but in DO-41 through-hole package; no metallic tab or integrated heat sink | Requires manual or wave soldering; unsuitable for high-density SMT layouts or thermal-critical designs | Select 1N5927B only if legacy through-hole assembly or lower-cost procurement is prioritized over thermal performance |
| BZX84-C12 | 12 V, ±5%, SOT-23 package; rated for 300 mW only; dynamic impedance ~30 Ω at 5 mA | Limited to low-power signal-level regulation; cannot sustain 3.0 W clamping duty cycles | Choose BZX84-C12 for space-constrained logic-level references where power dissipation is ≤300 mW |
Compared with 1N5927B and BZX84-C12, the 1PMT5927E3/TR13 delivers superior thermal management via its metallic tab and supports full 3.0 W operation-making it the only option among the three suitable for industrial-grade power rail clamping with sustained transient energy absorption.

FAQ
What is the zener voltage tolerance of the 1PMT5927E3/TR13?
The 1PMT5927E3/TR13 has a nominal zener voltage of 12 V with a standard tolerance of ±5%, measured at 31.2 mA test current and TAB 1 temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, respectively, but the E3/TR13 variant uses the standard ±5% grade.
How is thermal management handled in the 1PMT5927E3/TR13 package?
The 1PMT5927E3/TR13 uses the Powermite® package with a full metallic bottom and integral locking tab that serves as both mechanical anchor and primary thermal path. Its junction-to-TAB1 thermal resistance is 30°C/W, meaning effective heatsinking requires direct copper connection to TAB 1 on the PCB to maintain safe operating temperature under 3.0 W dissipation.
Can the 1PMT5927E3/TR13 replace a through-hole 1N5927B in an existing design?
No direct replacement is possible without layout revision: the 1PMT5927E3/TR13 is a surface-mount DO-216 device with TAB 1 cathode, while the 1N5927B is DO-41 through-hole with axial leads. Though electrically similar, their footprints, thermal paths, and assembly processes differ fundamentally-replacing one with the other requires PCB redesign and thermal validation.
What is the maximum reverse leakage current specification for the 1PMT5927E3/TR13?
The 1PMT5927E3/TR13 specifies a maximum reverse leakage current of 1 µA at a reverse voltage of 9.1 V (75% of nominal 12 V zener voltage), tested at TL = 30°C. This low leakage supports accurate voltage reference behavior and minimal standby power loss in always-on systems.
Is the 1PMT5927E3/TR13 suitable for automotive applications?
Yes-the 1PMT5927E3/TR13 operates from –55°C to +150°C junction temperature, exceeds 16 kV HBM ESD rating, and is qualified for industrial and automotive body electronics per Microsemi's internal stress testing. However, formal AEC-Q200 qualification is not claimed in the MSC0995 datasheet, so system-level validation is required for safety-critical automotive use.
