Product details
Overview
1PMT5932AE3/TR7 from Microsemi is a 20 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 14 Ω dynamic impedance at 18.7 mA test current and thermal resistance of 30°C/W junction-to-TAB1 - used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the 1PMT5932AE3/TR7 datasheet, 1PMT5932AE3/TR7 pinout, 1PMT5932AE3/TR7 application, or 1PMT5932AE3/TR7 equivalent, key selection criteria include zener voltage tolerance, power derating above 60°C, knee current (0.25 mA), reverse leakage (<1 µA at 15.2 V), and ESD robustness (>16 kV HBM).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its Powermite® package features a full metallic bottom for flux-free soldering and an integral locking tab acting as a heat sink, enabling reliable thermal transfer to PCB copper.
Designed for automatic insertion and reflow assembly, it supports high-reliability applications where low reverse leakage (<1 µA at VR = 15.2 V), tight voltage regulation (20 V ±5%), and robust ESD immunity (>16 kV HBM) are required without through-hole mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 20 V ±5% at IZT = 18.7 mA - defines nominal regulation point with predictable deviation across production lot |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power before thermal shutdown or degradation |
| Dynamic Impedance | 14 Ω at IZT - determines output voltage stability under small-signal current variation |
| Knee Current | 0.25 mA - minimum current needed to enter usable regulation region near VZ |
| Reverse Leakage | <1 µA at VR = 15.2 V - ensures minimal standby current in voltage-clamp or reference circuits |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables accurate PCB copper area sizing for thermal management |
| ESD Rating | >16 kV per Human Body Model - supports handling and assembly without external protection circuitry |
Pinout & Package
Package: Powermite® surface-mount package (DO-216 compatible outline), molded plastic body with full metallic bottom and integral heat-sink locking tab; cathode designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat path and electrical cathode connection; must be soldered to thermal pad for rated 3.0 W operation |
| Lead 2 | Anode | Standard anode terminal; mounted opposite TAB 1 on package body per DO-216 mechanical drawing |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling in footprint smaller than DO-41 |
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term solder joint reliability |
| Integral heat-sink locking tab | Provides direct thermal conduction path from junction to PCB copper, reducing θJA dependency on layout |
| ESD robustness >16 kV HBM | Allows safe handling and board-level integration without additional ESD protection components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF20A (ON Semiconductor) | 20 V, 400 W peak power, SOD-123FL package, 100 ns response, no specified HBM rating | Optimized for surge suppression rather than precision regulation | Select when transient clamping dominates over voltage reference stability |
| BZX84-C20 (Nexperia) | 20 V, ±5%, 350 mW, SOT-23 package, 60 Ω Zzt, no metallic thermal tab | Limited to low-power biasing due to lower power rating and higher thermal resistance | Select only for space-constrained, sub-500 mW reference applications |
Compared with SMF20A and BZX84-C20, the 1PMT5932AE3/TR7 uniquely combines 3.0 W continuous regulation, 30°C/W thermal resistance via metallic tab, and >16 kV HBM ESD rating - making it suitable for high-stability, thermally demanding, and ESD-prone environments where both precision and ruggedness are required.

FAQ
What is the zener voltage tolerance for 1PMT5932AE3/TR7?
The 1PMT5932AE3/TR7 has a standard zener voltage tolerance of ±5% at 20 V, measured at 18.7 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, but the E3/TR7 variant specifies ±5%. This tolerance directly impacts regulation accuracy in precision reference applications.
How much power can 1PMT5932AE3/TR7 dissipate continuously?
The 1PMT5932AE3/TR7 is rated for 3.0 W DC power dissipation when TAB 1 is maintained at 60°C. Power derating is required above this temperature - approximately 33 mW/°C reduction beyond 60°C - based on its 30°C/W junction-to-TAB thermal resistance. Exceeding this limit risks parametric shift or permanent failure.
What does the "E3/TR7" suffix indicate for 1PMT5932AE3/TR7?
The "E3/TR7" suffix denotes tape-and-reel packaging per EIA-481 standard, with 3,000 units per 7-inch reel. It does not affect electrical specifications. The base device is 1PMT5932B; E3/TR7 confirms packaging format and complies with automated assembly requirements for SMT lines.
Is 1PMT5932AE3/TR7 suitable for automotive applications?
Yes, 1PMT5932AE3/TR7 supports automotive use with its -55°C to +150°C junction/storage temperature range, >16 kV HBM ESD rating, and robust Powermite® package. It is commonly deployed in body control modules and infotainment power rails, though AEC-Q200 qualification status must be verified separately per application requirements.
What is the cathode identification method for 1PMT5932AE3/TR7?
The cathode of 1PMT5932AE3/TR7 is designated by TAB 1, which is the larger metallic tab on the package bottom. Mechanical drawings confirm TAB 1 as cathode per DO-216 outline, and correct orientation is essential for proper voltage clamping - reverse mounting will result in forward conduction instead of Zener regulation.
