Product details
Overview
P6SMB11CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features 11 V standoff voltage (VWM), 12.1 V minimum breakdown voltage (VBR), 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB11CAHM3/H datasheet, P6SMB11CAHM3/H pinout, P6SMB11CAHM3/H application, or P6SMB11CAHM3/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), MSL Level 1 moisture sensitivity, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes.
Designed for automated SMT placement, it uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker resistance. The SMB package supports 0.2" × 0.2" copper pad layout for optimal thermal dissipation under repetitive 0.01% duty cycle surges.
Key Specifications

|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential or single-ended signal lines upstream of interface ICs. Use Value: Limits transient voltage to ≤15.6 V during 38.5 A surges, preventing latch-up or gate oxide damage in 3.3 V/5 V automotive microcontrollers. |
Use Scenario: Shielding 24 V digital input modules in programmable logic controllers from inductive kickback and EFT bursts. IC Role / Device Role / Timing Role: Parallel-connected TVS on each channel input, referenced to common ground to shunt surge energy away from optocoupler inputs. Use Value: Clamps 10/1000 μs transients to 15.6 V while maintaining <5 μA leakage at 9.4 V - preserves input threshold accuracy and noise immunity. |
| Consumer Appliance Motor Drive Protection | Telecom Line Card Surge Suppression |
|
Use Scenario: Safeguarding half-bridge gate drivers and MCU GPIOs in washing machine motor control boards exposed to relay contact bounce and winding back-EMF. IC Role / Device Role / Timing Role: Localized TVS at MOSFET source/drain nodes and microcontroller reset lines to absorb sub-microsecond spikes. Use Value: Responds in <1 ns to suppress >100 V transients before propagation into logic circuits - prevents false resets and erratic PWM behavior. |
Use Scenario: Front-end protection of Ethernet PHYs and PoE injectors against lightning-induced surges on twisted-pair cabling per IEC 61000-4-5. IC Role / Device Role / Timing Role: Differential-mode TVS pair across data pairs (e.g., TX+/TX−), combined with common-mode chokes. Use Value: Symmetric 15.6 V clamping ensures balanced suppression without skewing differential signaling integrity at 100 Mbps+ data rates. |
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-T | Same VWM (9.4 V), VC (15.6 V), and PPPM (600 W); differs in packaging (tape/reel quantity) and qualification level (commercial only, not AEC-Q101) | Lacks automotive qualification; suitable for consumer/industrial use where AEC-Q101 is not mandated | Select when cost sensitivity outweighs automotive reliability requirements and board space/layout matches SMB footprint |
| 1.5SMC11CA | Higher package thermal resistance (RθJA ≈ 120 °C/W vs. 100 °C/W); same electrical specs but larger SMC (DO-214AB) outline (7.11 mm × 6.22 mm) | Requires larger PCB area and may limit high-density routing; better suited for higher average power dissipation scenarios | Choose only if existing layout accommodates SMC size or if enhanced thermal margin justifies footprint increase |
Compared with SMBJ11CA-T and 1.5SMC11CA, P6SMB11CAHM3/H uniquely combines AEC-Q101 qualification, halogen-free compliance, and SMB footprint - making it the preferred choice for space-constrained automotive and industrial designs requiring certified reliability without layout revision.

FAQ
What does the 'CA' suffix indicate in P6SMB11CAHM3/H?
The 'CA' suffix in P6SMB11CAHM3/H denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. This eliminates polarity marking on the SMB package and allows flexible placement across AC-coupled or floating signal paths without regard to anode/cathode orientation - a key advantage over unidirectional variants like P6SMB11AHM3/H.
Is P6SMB11CAHM3/H qualified for automotive applications?
Yes, P6SMB11CAHM3/H is AEC-Q101 qualified, as confirmed by the 'HM3' suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It has undergone rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D, making it suitable for engine control units, ADAS sensors, and body electronics where reliability under thermal and vibration stress is mandatory.
What is the maximum clamping voltage of P6SMB11CAHM3/H and under what test condition?
The maximum clamping voltage of P6SMB11CAHM3/H is 15.6 V, measured at a peak pulse current (IPPM) of 38.5 A using the standard 10/1000 μs double-exponential waveform. This value represents the worst-case voltage imposed on protected circuitry during a surge event and is guaranteed across the full operating temperature range of −65 °C to +150 °C.
How does the SMB package of P6SMB11CAHM3/H compare to SMC or SMA alternatives?
The SMB (DO-214AA) package of P6SMB11CAHM3/H measures 4.57 mm × 3.94 mm × 2.20 mm - significantly smaller than SMC (DO-214AB) and slightly more compact than SMA (DO-214AC). Its lower thermal resistance (RθJA = 100 °C/W vs. ~120 °C/W for SMC) and MSL Level 1 rating enable direct placement in high-density automotive PCBs without baking, unlike larger alternatives that require moisture-sensitive handling protocols.
Does P6SMB11CAHM3/H require external heat sinking for 600 W pulse handling?
No, P6SMB11CAHM3/H achieves its rated 600 W peak pulse power with a 10/1000 μs waveform using only the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad per terminal - no external heatsink needed. Its RθJL of 20 °C/W and RθJA of 100 °C/W are characterized under this layout; exceeding pad size yields marginal improvement, but undersizing risks thermal runaway during repetitive surges.
