Product details
Overview
P6SMB11CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal and power lines. It features a 11 V standoff voltage (VWM), 15.6 V maximum clamping voltage at 38.5 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the P6SMB11CAHE3_A/I datasheet, P6SMB11CAHE3_A/I pinout, P6SMB11CAHE3_A/I application, or P6SMB11CAHE3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, SMB (DO-214AA) package thermal resistance (RθJA = 100 °C/W), and compliance with J-STD-020 MSL level 1 reflow profile.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding its breakdown threshold (VBR min = 10.5 V, max = 11.6 V at 1 mA), it rapidly switches to low-impedance conduction to divert surge current away from downstream circuitry. Its bidirectional architecture ensures symmetrical clamping in both polarities without polarity marking.
Thermally, it sustains operation up to TJ = 150 °C with derated pulse power above TA = 25 °C per Fig. 2; mounted on 5.0 mm × 5.0 mm copper pads, it achieves 600 W peak pulse rating under standard 10/1000 μs test conditions. The glass-passivated junction enables fast response time (< 1.0 ns) and low incremental surge resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 9.40 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping onset. |
| VBR (Breakdown Voltage) | 10.5 V to 11.6 V at 1 mA - Voltage at which device enters avalanche conduction; tight tolerance supports predictable protection threshold. |
| VC (Clamping Voltage) | 15.6 V at IPPM = 38.5 A - Maximum voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capacity under standardized waveform; enables robust protection against IEC 61000-4-5 Level 3/4 surges. |
| ID (Reverse Leakage) | 5.0 μA at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | 150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial ambient environments. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated placement and reflow soldering. |

Use Scenario: Protecting CAN FD transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional shunt clamp placed directly at connector entry point to limit transient voltage before reaching ASIC or microcontroller input pins. Use Value: Maintains signal fidelity under ±100 V/50 ms load dump events while enabling direct connection to AEC-Q100 qualified SoCs without external RC filtering. |
Use Scenario: Safeguarding 24 V DC digital input cards in PLCs against field-wiring induced surges and inductive kickback from solenoid valves. IC Role / Device Role / Timing Role: Primary overvoltage clamp across input terminals, working in conjunction with series current-limiting resistor and optocoupler isolation barrier. Use Value: Limits clamped voltage to ≤15.6 V, ensuring optocoupler LED forward voltage remains within safe operating range and preventing false triggering. |
| Telecom Line Interface | Consumer USB Port ESD Protection |
|
Use Scenario: Shielding RS-485 transceivers and Ethernet PHYs from lightning-induced surges on long cable runs in building automation networks. IC Role / Device Role / Timing Role: First-line transient suppressor on differential bus lines (A/B), coordinated with common-mode chokes and secondary TVS arrays. Use Value: Clamps common-mode surges to <16 V while preserving differential signal swing integrity - meets IEC 61000-4-5 4 kV surge immunity requirement. |
Use Scenario: Adding secondary surge protection on USB 2.0 data lines (D+/D−) behind primary ESD diodes in portable medical devices and smart home hubs. IC Role / Device Role / Timing Role: High-energy backup clamp activated only during sustained overvoltage events beyond ESD diode capability (e.g., hot-plug inductive spikes). Use Value: Absorbs >600 W surge energy without failure, preventing latch-up or permanent damage to USB controller ICs during non-ESD fault conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | Same SMB package, identical VWM (9.4 V) and VC (15.6 V), but rated for 600 W with tighter VBR tolerance (10.5–11.6 V vs. 10.5–11.6 V); not AEC-Q101 qualified. | Lacks automotive qualification; suitable for commercial/industrial use where AEC-Q101 is not mandated. | Select SMBJ11CA when cost optimization is prioritized and automotive qualification is unnecessary. |
| 1.5KE11CA | Through-hole DO-201 package, same 11 V bidirectional rating, 600 W rating, but higher RθJA (~50 °C/W on FR-4) and slower response due to larger junction capacitance. | Requires PCB real estate for axial/lead mounting; less suitable for space-constrained or high-density layouts. | Choose 1.5KE11CA only if legacy through-hole assembly is required or thermal mass of board layout provides sufficient heat sinking. |
Compared with SMBJ11CA and 1.5KE11CA, P6SMB11CAHE3_A/I uniquely combines AEC-Q101 qualification, surface-mount SMB footprint, and MSL Level 1 compatibility - making it the optimal choice for new automotive and high-reliability industrial designs requiring zero rework risk and validated lifetime performance.

FAQ
What does the "HE3_A/I" suffix indicate in P6SMB11CAHE3_A/I?
The "HE3" denotes RoHS-compliant and AEC-Q101 qualified construction; "A" is the revision code per Vishay's internal documentation; "I" specifies packaging in 13-inch diameter plastic tape and reel (3200 units per reel). This suffix confirms full automotive qualification, halogen-free materials, and industry-standard surface-mount delivery format - all verified in Vishay document 88370, revision 09-Jan-2024.
Is P6SMB11CAHE3_A/I unidirectional or bidirectional?
P6SMB11CAHE3_A/I is a bidirectional TVS diode, as confirmed by the "CA" suffix in its part number and explicitly stated in Vishay's P6SMB series datasheet: "For bidirectional devices use CA suffix (e.g., P6SMB10CA). Electrical characteristics apply in both directions." Its symmetric clamping behavior eliminates need for polarity orientation during placement.
What is the maximum clamping voltage of P6SMB11CAHE3_A/I and under what test condition?
The maximum clamping voltage (VC) of P6SMB11CAHE3_A/I is 15.6 V, measured at a peak pulse current (IPPM) of 38.5 A using the standardized 10/1000 μs double-exponential waveform per Figure 1 in Vishay document 88370. This value represents the worst-case voltage imposed on protected circuitry during surge events.
Does P6SMB11CAHE3_A/I meet JEDEC moisture sensitivity requirements?
Yes, P6SMB11CAHE3_A/I meets MSL Level 1 per J-STD-020, with a maximum lead-free reflow peak temperature of 260 °C. This is documented in the "MECHANICAL DATA" section of Vishay's P6SMB datasheet (document 88370), confirming no floor life limitation or baking requirement prior to assembly.
How does the thermal resistance of P6SMB11CAHE3_A/I affect its surge handling capability?
P6SMB11CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads. This value directly limits its ability to sustain repetitive surges: above TA = 25 °C, pulse power must be derated per Figure 2 in Vishay document 88370 to prevent junction overheating and parametric shift.
