Product details
Overview
1PMT5956AE3/TR7 from Microsemi is a 200 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 1.9 mA test current (IZT), 1200 Ω dynamic impedance (ZZT), and 11.6 mA maximum Zener current (IZM). It serves as a precision voltage reference or overvoltage clamp in high-voltage DC power rails and industrial sensor interfaces.
For engineers reviewing the 1PMT5956AE3/TR7 datasheet, 1PMT5956AE3/TR7 pinout, 1PMT5956AE3/TR7 application, or 1PMT5956AE3/TR7 equivalent, key selection criteria include its 200 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heat sinking, low reverse leakage (<8 µA at VR = 152 V), ESD rating >16 kV HBM, and DO-216 mechanical outline compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified IZK–IZM range. Its Powermite® package integrates a full metallic bottom and locking tab to ensure reliable thermal conduction from junction to PCB copper, enabling stable 3.0 W operation without external heatsinking when mounted on ≥1 sq-in 2-oz copper.
The device exhibits low knee impedance (ZZK = 0.25 Ω) and maintains <8 µA reverse leakage at VR = 152 V, supporting accurate clamping in high-impedance feedback networks. Voltage tolerance is ±5% standard (suffix 'E'), with optional ±2% ('C') and ±1% ('D') versions available.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 200 V ±5% at IZT = 1.9 mA - defines precise clamping threshold for 150–250 V DC bus protection |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables direct PCB heat sinking without added thermal vias or heatsinks |
| Dynamic Impedance (ZZT) | 1200 Ω at IZT - determines voltage deviation under load transients; critical for stable reference accuracy |
| Reverse Leakage (IR) | <8 µA at VR = 152 V - ensures minimal standby current in high-impedance bias networks |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt; supports thermal design with known PCB copper area |
| ESD Rating | >16 kV HBM - provides robust handling during automated placement and board-level ESD events |
| Knee Current (IZK) | 0.25 mA - minimum current needed to enter regulated breakdown; sets lower limit for bias network design |
Pinout & Package
Package: Powermite® (DO-216AA), molded surface-mount package with full metallic bottom and integral locking tab acting as cathode terminal (TAB 1). Cathode is unambiguously designated by TAB 1 per mechanical specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking path and electrical cathode connection; must be soldered to copper pour for thermal compliance |
| Lead 2 | Anode | Standard anode terminal; connects to ground or low-side reference point in clamping configuration |
Key Features
| Feature | Design Value |
|---|---|
| Full metallic bottom | Eliminates solder flux entrapment during reflow, ensuring void-free thermal interface and long-term reliability |
| Integral locking tab | Acts as both mechanical anchor and primary thermal path-reduces junction-to-PCB thermal resistance by ~40% vs. standard SOD-123 |
| ESD robustness | >16 kV HBM rating enables safe handling in unshielded production environments without special ESD controls |
| Automated insertion compatibility | DO-216 footprint and symmetric geometry support high-yield pick-and-place at >25,000 UPH with standard nozzles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ200A | TVS diode, 200 V standoff, 3.0 kW peak pulse power, bidirectional, higher clamping voltage (224 V min) | Designed for transient suppression (IEC 61000-4-5), not precision DC regulation | Select for surge immunity; avoid where low-leakage DC reference is required |
| 1N5388B | Through-hole 200 V Zener, 5 W, DO-201AD package, 35°C/W junction-to-lead thermal resistance | Larger footprint, manual assembly only, inferior thermal performance on PCB | Select only if legacy through-hole design or higher continuous power (>3.0 W) is mandatory |
Compared with SMCJ200A and 1N5388B, the 1PMT5956AE3/TR7 uniquely combines 200 V precision regulation, 3.0 W SMT-compatible power handling, and sub-8 µA leakage-making it optimal for space-constrained, high-reliability DC reference and clamping where thermal management and long-term stability are critical.

FAQ
What is the Zener voltage tolerance for 1PMT5956AE3/TR7?
The 1PMT5956AE3/TR7 has a standard Zener voltage tolerance of ±5% at 200 V, as indicated by the 'E' suffix in the part number. This tolerance is measured at IZT = 1.9 mA with TAB 1 held at 30°C. Tighter tolerances of ±2% ('C') and ±1% ('D') are available upon request but are not applicable to the 1PMT5956AE3/TR7 variant.
How is thermal management achieved in the 1PMT5956AE3/TR7 Powermite® package?
The 1PMT5956AE3/TR7 uses its full metallic bottom and integral locking tab (TAB 1) as the primary thermal conduction path from junction to PCB. With a specified thermal resistance of 30°C/W junction-to-TAB1, effective cooling requires soldering TAB 1 to ≥1 square inch of 2-ounce copper. This eliminates need for external heatsinks while sustaining 3.0 W DC dissipation.
Can 1PMT5956AE3/TR7 be used in place of a through-hole 200 V Zener like 1N5388B?
The 1PMT5956AE3/TR7 is not a drop-in replacement for 1N5388B due to different packages (DO-216 vs. DO-201AD), thermal paths, and mounting methods. While both regulate at 200 V, the 1PMT5956AE3/TR7 offers superior SMT compatibility and lower thermal resistance (30°C/W vs. 35°C/W), but lower absolute power rating (3.0 W vs. 5.0 W). Board redesign is required.
What is the maximum reverse leakage current for 1PMT5956AE3/TR7 at rated conditions?
At VR = 152 V (76% of nominal VZ), the 1PMT5956AE3/TR7 guarantees reverse leakage current ≤8 µA. This value is measured at TL = 30°C and is critical for maintaining accuracy in high-impedance voltage divider or reference circuits where leakage-induced error must remain below 0.01%.
Is 1PMT5956AE3/TR7 compatible with lead-free reflow processes?
Yes, the 1PMT5956AE3/TR7 is qualified for standard lead-free reflow profiles (JEDEC J-STD-020), including peak temperatures up to 260°C. Its molded Powermite® package and metallic terminals withstand thermal cycling without delamination or solder joint fracture, and the full metallic bottom prevents flux entrapment during reflow-ensuring high first-pass yield.
