Product details
Overview
P6SMB200CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), designed to protect sensitive signal lines and power rails in automotive and industrial electronics against ESD and lightning-induced transients.
For engineers reviewing the P6SMB200CAHE3/52 datasheet, P6SMB200CAHE3/52 pinout, P6SMB200CAHE3/52 application, or P6SMB200CAHE3/52 equivalent, this device delivers AEC-Q101 qualification, 600 W peak pulse power (10/1000 μs), low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive ECUs and industrial sensor interfaces requiring robust transient immunity without layout redesign.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction enables fast response time (<1 ns) and stable clamping under repetitive 10/1000 μs surges at 0.01% duty cycle.
Thermal performance is defined by RθJA = 100 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W (junction-to-lead), supporting reliable operation up to TJ = +150 °C. The device meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 220 V min - Voltage at which device enters avalanche conduction; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 274 V max at IPPM = 2.2 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capability per IEC 61000-4-5 waveform; validates protection level for industrial surge standards. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Minimal DC leakage at rated standoff; preserves signal integrity and low-power operation. |
| TJ max | +150 °C - Maximum junction temperature; enables deployment in under-hood automotive environments and high-ambient industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200CA | Same VWM (200 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 150 °C/W) | Limited to lower-energy transients; unsuitable for AEC-Q101 automotive use | Select when board space is constrained and surge energy does not exceed 400 W. |
| 1.5KE200CA | Higher PPPM (1500 W), axial-leaded DO-201 package, non-AEC-Q101, higher VC (324 V) | Requires through-hole mounting; clamps at higher voltage, increasing risk to protected ICs | Choose only for legacy through-hole designs where 324 V clamping is acceptable and reflow compatibility is not required. |
Compared with SMAJ200CA and 1.5KE200CA, P6SMB200CAHE3/52 uniquely combines AEC-Q101 qualification, 600 W surge rating, SMB surface-mount compatibility, and 274 V clamping - making it the optimal choice for new automotive and industrial PCB designs demanding high reliability and compact layout.

FAQ
What is the clamping voltage of P6SMB200CAHE3/52 at its rated peak pulse current?
The P6SMB200CAHE3/52 has a maximum clamping voltage (VC) of 274 V at its specified peak pulse current (IPPM) of 2.2 A, measured using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during surge events. The clamping behavior remains symmetrical in both directions due to its bidirectional construction.
Is P6SMB200CAHE3/52 suitable for automotive applications?
Yes, P6SMB200CAHE3/52 is AEC-Q101 qualified (indicated by the HE3 suffix), having passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD per JESD22-A114. It is explicitly intended for automotive use cases such as CAN bus protection, body control modules, and infotainment power rails where reliability under thermal and electrical stress is critical.
What is the standoff voltage rating of P6SMB200CAHE3/52, and how does it relate to system design?
The standoff voltage (VWM) of P6SMB200CAHE3/52 is 200 V - the maximum continuous DC or RMS voltage the device can withstand without entering avalanche conduction. In system design, this value must exceed the normal operating voltage of the protected line (e.g., 12 V, 24 V, or 48 V rails) with sufficient margin to avoid leakage or premature clamping. For 200 V-rated systems, P6SMB200CAHE3/52 provides minimal headroom and is typically used in high-voltage DC links or telecom line interfaces.
Does P6SMB200CAHE3/52 require special PCB layout considerations?
Yes - to achieve rated 600 W pulse power, P6SMB200CAHE3/52 must be mounted on minimum recommended pad layout: 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per Vishay Document 88370. Smaller pads increase thermal resistance and reduce effective surge rating. Additionally, short, low-inductance traces to ground or return paths are essential to preserve sub-nanosecond response and minimize voltage overshoot during fast transients.
How does the bidirectional nature of P6SMB200CAHE3/52 affect its placement in circuit protection schemes?
The bidirectional configuration of P6SMB200CAHE3/52 allows it to suppress transients of either polarity without regard to orientation - ideal for AC-coupled lines (e.g., RS-485, CAN, telephone lines) or differential pairs where voltage reversal occurs. Unlike unidirectional TVS diodes, P6SMB200CAHE3/52 has no cathode band marking and installs without polarity verification, simplifying automated placement and reducing assembly errors in high-volume manufacturing.
