Product details
Overview
P6SMB10CAHM3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 10 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 41.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects signal lines and power rails in automotive sensor units, industrial I/O interfaces, and telecom front-end circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB10CAHM3_B/H datasheet, P6SMB10CAHM3_B/H pinout, P6SMB10CAHM3_B/H application, or P6SMB10CAHM3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and halogen-free RoHS compliance - all confirmed for this specific ordering code.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its glass-passivated junction ensures stable leakage performance (<10 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of sub-microsecond transients induced by relay switching or ESD events.
The P6SMB10CAHM3_B/H is thermally optimized for surface-mount PCB layouts using 0.2" × 0.2" copper pads per terminal, delivering RθJA = 100 °C/W and supporting continuous operation up to TJ = 150 °C. Its 600 W PPPM rating is specified under repetitive 0.01% duty cycle conditions with 10/1000 μs waveform per IEC 61000-4-5.

FAQ
What does the "HM3_B/H" suffix mean in P6SMB10CAHM3_B/H?
The "HM3" denotes halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance; "B" indicates AEC-Q101 qualification for the 6.8 V to 220 V voltage range; "H" specifies 7" tape-and-reel packaging (750 units per reel). This full suffix confirms P6SMB10CAHM3_B/H meets automotive-grade reliability, environmental compliance, and automated assembly requirements.
Is P6SMB10CAHM3_B/H unidirectional or bidirectional?
P6SMB10CAHM3_B/H is a bidirectional TVS diode, as indicated by the "CA" suffix. It provides symmetrical clamping in both polarities - essential for protecting AC-coupled lines, differential buses like CAN, or any circuit where voltage transients may swing above or below ground. No polarity marking is present on the SMB package.
What is the maximum clamping voltage of P6SMB10CAHM3_B/H and under what test condition?
The maximum clamping voltage (VC) of P6SMB10CAHM3_B/H is 14.5 V, measured at a peak pulse current (IPPM) of 41.4 A using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and defines the worst-case voltage imposed on protected circuitry during a full-rated surge event.
Does P6SMB10CAHM3_B/H require derating at elevated ambient temperatures?
Yes - P6SMB10CAHM3_B/H must be derated above TA = 25 °C per Figure 2 in the datasheet. At 85 °C ambient, its peak pulse power drops to approximately 420 W (70% of 600 W), and at 125 °C, it falls to ~240 W (40%). Derating ensures junction temperature remains ≤150 °C during repetitive surge events.
Can P6SMB10CAHM3_B/H replace P6SMB10A in an existing design?
No - P6SMB10CAHM3_B/H is bidirectional, while P6SMB10A is unidirectional. Swapping them without circuit review risks improper clamping during negative transients and potential damage to downstream components. The "CA" vs. "A" suffix defines fundamental conduction behavior; replacement requires verification of polarity requirements and clamping symmetry in the target application.
