Product details
Overview
1PMT5932C/TR7 from Microsemi is a 20 V, ±1% 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 15.2 mA maximum Zener current - used for precision voltage regulation in compact power supply rails and overvoltage protection circuits.
For engineers reviewing the 1PMT5932C/TR7 datasheet, 1PMT5932C/TR7 pinout, 1PMT5932C/TR7 application, or 1PMT5932C/TR7 equivalent, key selection criteria include tight voltage tolerance (±1%), low dynamic impedance, ESD rating >16 kV HBM, thermal resistance of 30°C/W junction-to-TAB, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates as a two-terminal voltage reference device with cathode designated by TAB 1. It delivers stable 20 V regulation under DC bias at IZT = 18.7 mA, with knee current IZK = 0.25 mA and knee impedance ZZK = 650 Ω - enabling reliable turn-on in low-current monitoring paths.
The Powermite® package integrates a full metallic bottom and locking tab that serves as both mechanical anchor and thermal path to PCB copper, achieving 30°C/W junction-to-TAB thermal resistance and eliminating solder flux entrapment during reflow.
Key Specifications

Use Value: 3.0 W rating handles short-duration surge energy; metallic bottom ensures repeatable thermal performance across batches. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C20LT1G | 20 V ±5%, 300 mW, SOT-23 package, ZZT = 50 Ω at 5 mA | Limited to low-power biasing; unsuitable for 3 W clamping or high-current regulation | Select when board space is critical and power < 0.3 W; avoid for thermal-intensive roles |
| SMBJ20A | 20 V standoff, 600 W peak pulse power, unidirectional TVS, 1.5 V clamping voltage @ 10 A | Designed for transient suppression only - not for DC regulation or precision reference | Select only for surge-only protection; cannot replace 1PMT5932C/TR7 in voltage reference circuits |
Compared with BZX84-C20LT1G and SMBJ20A, the 1PMT5932C/TR7 uniquely combines ±1% DC regulation accuracy, 3.0 W continuous dissipation, and 30°C/W thermal resistance - making it irreplaceable in compact, thermally demanding Zener reference and clamping applications.

FAQ
What is the Zener voltage tolerance for 1PMT5932C/TR7?
The "C" suffix in 1PMT5932C/TR7 denotes ±1% Zener voltage tolerance at 20 V nominal, verified at IZT = 18.7 mA and TAB temperature of 30°C. This tighter tolerance enables direct use in precision reference circuits without calibration or trimming, distinguishing it from the ±5% "B" version (1PMT5932B/TR7).
How is thermal performance managed in the 1PMT5932C/TR7 Powermite® package?
The 1PMT5932C/TR7 achieves 30°C/W junction-to-TAB thermal resistance via its full metallic bottom and integral locking tab, which anchors TAB 1 directly to PCB copper. This design eliminates flux entrapment and enables 3.0 W continuous dissipation at TAB 1 = 60°C - far exceeding standard SMT Zener capabilities.
Is the 1PMT5932C/TR7 compatible with automated SMT assembly processes?
Yes, the 1PMT5932C/TR7 is fully compatible with automated insertion equipment and standard reflow profiles. Its Powermite® package features symmetric geometry, defined tape-and-reel packaging per EIA-481, and a locking tab that prevents rotation during placement - ensuring high first-pass yield in high-volume manufacturing.
What does the "TR7" suffix indicate in 1PMT5932C/TR7?
The "TR7" suffix indicates tape-and-reel packaging per EIA-481 standard on a 7-inch reel containing 3,000 units. This format supports automated pick-and-place systems and is distinct from bulk or ammo-pack options - critical for consistent SMT line feeding and inventory traceability.
Can 1PMT5932C/TR7 be used as a substitute for 1N4740A in existing designs?
No - while both regulate at ~20 V, the 1PMT5932C/TR7 is a surface-mount Powermite® device with TAB-1 cathode and 3.0 W rating, whereas the 1N4740A is a through-hole DO-41 device rated for 1.0 W. Substitution requires PCB layout change, thermal redesign, and validation of ESD and surge behavior due to structural and packaging differences.
