Product details
Overview
1PMT5934BE3/TR7 from Microsemi is a 24 V ±5% surface-mount Zener diode in the Powermite® package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with dynamic impedance of 19 Ω at 15.6 mA test current and reverse leakage ≤1 µA at 18.2 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5934BE3/TR7 datasheet, 1PMT5934BE3/TR7 pinout, 1PMT5934BE3/TR7 application, or 1PMT5934BE3/TR7 equivalent, key selection criteria include its 24 V zener voltage tolerance, 3.0 W thermal capability with metallic-tab heatsinking, low knee impedance (700 Ω at 0.25 mA), ESD rating >16 kV HBM, and DO-216 mechanical form factor.
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 from junction to PCB pad, enabling reliable 3.0 W power handling without external heatsinks.
The device exhibits low dynamic impedance (19 Ω) at IZT = 15.6 mA and maintains stable regulation down to knee current IZK = 0.25 mA, where ZZK = 700 Ω - critical for low-current biasing and sensing applications requiring minimal voltage drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 24 V ±5% at IZT = 15.6 mA - defines nominal regulation point with production tolerance band |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous DC power transferable via metallic tab to PCB |
| Dynamic Impedance ZZT | 19 Ω at IZT = 15.6 mA - determines output voltage variation under load current changes |
| Knee Impedance ZZK | 700 Ω at IZK = 0.25 mA - indicates regulation onset threshold for low-current operation |
| Reverse Leakage IR | ≤1 µA at VR = 18.2 V - ensures minimal standby current in clamping or reference configurations |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt, enabling thermal design with PCB copper area |
| ESD Rating | >16 kV per Human Body Model - supports robust handling and board-level ESD immunity |
Pinout & Package
Package: Powermite® (DO-216AA), molded surface-mount package with full metallic bottom and integral locking tab acting as thermal path and mechanical anchor. Cathode designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal; must be soldered to copper pour for rated 3.0 W dissipation |
| Lead 2 | Anode | Standard anode connection; electrically isolated from TAB 1; used for circuit return path |
Key Features
| Feature | Design Value |
|---|---|
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and void-free solder joints |

| ESD robustness | >16 kV HBM rating enables safe handling and integration into unshielded industrial control interfaces |
| Automated assembly compatibility | DO-216 footprint and tape-and-reel packaging (EIA-481, 3,000 pcs/7″ reel) support high-speed pick-and-place |
Applications
| DC Power Rail Clamping | Feedback Reference in SMPS |
|---|---|
Use Scenario: Protecting 24 V industrial I/O lines against transient surges up to ±1 kV. IC Role / Device Role / Timing Role: Zener clamping element shunting excess energy to ground when voltage exceeds 24 V + tolerance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF24A (ON Semiconductor) | 24 V, 1.0 W SOD-123 package; no metallic tab; RθJA = 180°C/W vs. 30°C/W | Limited to lower-power clamping; unsuitable for sustained 3.0 W dissipation | Select when board space is constrained and peak power <1 W; avoid for thermal-critical 24 V rail protection |
| BZX84-C24 (Diodes Inc.) | 24 V, 300 mW SOT-23; ±5% tolerance; ZZT = 80 Ω at 5 mA | Not rated for >0.3 W; higher dynamic impedance limits regulation accuracy under load | Use only in low-current reference or signal-level clamping; cannot replace 1PMT5934BE3/TR7 in power rail roles |
Compared with SMF24A and BZX84-C24, the 1PMT5934BE3/TR7 delivers 3× higher power handling and 6× lower thermal resistance due to its Powermite® metallic-tab construction - making it uniquely suitable for industrial 24 V systems demanding sustained clamping and long-term reliability.

FAQ
What is the zener voltage tolerance for 1PMT5934BE3/TR7?
The 1PMT5934BE3/TR7 has a nominal zener voltage of 24 V with a standard tolerance of ±5%, measured at IZT = 15.6 mA and TAB 1 temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, but the E3/TR7 variant specifies ±5%.
How much power can 1PMT5934BE3/TR7 dissipate continuously?
The 1PMT5934BE3/TR7 is rated for 3.0 W DC power dissipation when TAB 1 is maintained at 60°C. This rating depends on adequate PCB copper area for heat spreading; derating is required above 60°C TAB temperature per the device's 30°C/W thermal resistance specification.
Is 1PMT5934BE3/TR7 compatible with automated SMT assembly?
Yes, the 1PMT5934BE3/TR7 is supplied in EIA-481 tape-and-reel format (3,000 pieces per 7-inch reel) and features a DO-216AA outline optimized for pick-and-place equipment. Its locking tab and coplanar leads ensure stable placement and reliable reflow soldering without tombstoning.
What is the cathode identification method for 1PMT5934BE3/TR7?
The cathode of the 1PMT5934BE3/TR7 is designated by TAB 1 - the larger metallic terminal visible on the bottom side of the Powermite® package. The anode is Lead 2, and polarity must be observed during PCB layout to ensure correct reverse-bias operation in Zener applications.
Does 1PMT5934BE3/TR7 meet industrial temperature requirements?
Yes, the 1PMT5934BE3/TR7 is specified for junction and storage temperatures from -55°C to +150°C, making it suitable for industrial, automotive under-hood, and outdoor equipment applications where extended thermal range and reliability are mandatory.
