Product details
Overview
P6SMB16CAHM3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 16 V standoff voltage (VWM), 17.1 V minimum breakdown voltage (VBR), and 600 W peak pulse power rating at 10/1000 μs waveform - designed to protect signal lines and power rails in automotive sensor units and industrial control interfaces against ESD and inductive switching transients.
For engineers reviewing the P6SMB16CAHM3_B/H datasheet, P6SMB16CAHM3_B/H pinout, P6SMB16CAHM3_B/H application, or P6SMB16CAHM3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, and thermal resistance (RθJA = 100 °C/W) for board-level surge protection in space-constrained designs.
Technical Context
This device operates as a voltage-clamped transient suppressor with symmetrical reverse/forward conduction behavior due to its bidirectional architecture, enabling protection of AC-coupled or differential signal paths without polarity sensitivity. It exhibits low incremental surge resistance and fast response time (<1 ns), ensuring effective clamping before downstream ICs experience overvoltage stress.
Designed for mounting on 0.2" × 0.2" copper pads per terminal, the P6SMB16CAHM3_B/H delivers 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current (IPPM), with temperature coefficient of VBR at +0.086 %/°C - supporting stable performance across -65 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13.6 V - maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 15.2–16.8 V at 1 mA test current - ensures reliable avalanche initiation within specified tolerance band |
| VC (Clamping Voltage) | 22.5 V at 26.7 A IPPM - limits transient voltage seen by protected circuitry during 10/1000 μs surge |
| PPPM (Peak Pulse Power) | 600 W - sustains standardized lightning/surge immunity per IEC 61000-4-5 when mounted per recommended pad layout |
| RθJA | 100 °C/W - determines thermal rise under sustained 5.0 W power dissipation; requires PCB copper area management |
| TJ max. | +150 °C - enables operation in under-hood automotive environments and industrial enclosures |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTOL, TC, and HAST |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA | 400 W PPPM, SMA package (larger RθJA = 140 °C/W), same VWM/VBR range | Limited to lower-energy transients; less suitable for automotive AEC-Q101 environments | Select when cost sensitivity outweighs automotive qualification and higher surge margin |
| 1.5KE16CA | Through-hole DO-201 package, 1500 W PPPM, higher VC (26 V), no AEC-Q101 qualification | Better for high-energy surges but incompatible with SMT automation and space-constrained boards | Choose only for legacy through-hole designs requiring higher peak power, not for new automotive or industrial SMT platforms |
Compared with SMAJ16CA and 1.5KE16CA, the P6SMB16CAHM3_B/H uniquely combines AEC-Q101 qualification, 600 W surge rating, SMB footprint, and halogen-free compliance - making it the preferred choice for next-generation automotive and industrial SMT designs demanding reliability, density, and regulatory alignment.

FAQ
What does the "CA" suffix indicate in P6SMB16CAHM3_B/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB16CAHM3_B/H provides symmetrical clamping in both polarities - essential for protecting AC-coupled signals, differential buses like CAN or RS-485, and circuits where voltage polarity reversal may occur during transients. This differs from unidirectional "A" variants that require correct cathode orientation.
Is P6SMB16CAHM3_B/H suitable for automotive applications?
Yes, the P6SMB16CAHM3_B/H is AEC-Q101 qualified (indicated by the HM3 suffix), tested for high-temperature operating life, thermal cycling, and humidity exposure per automotive reliability standards. Its 150 °C max junction temperature and halogen-free construction make it appropriate for engine bay, body control, and ADAS sensor module designs.
What is the maximum clamping voltage of P6SMB16CAHM3_B/H and how is it measured?
The P6SMB16CAHM3_B/H has a maximum clamping voltage (VC) of 22.5 V, measured at 26.7 A peak pulse current (IPPM) using a standardized 10/1000 μs double-exponential waveform. This value represents the highest voltage imposed on the protected circuit during a defined surge event, verified under JEDEC test conditions with specified PCB mounting.
How does the SMB package of P6SMB16CAHM3_B/H compare to SMA or SMC in terms of thermal performance?
The SMB (DO-214AA) package of P6SMB16CAHM3_B/H offers a thermal resistance of RθJA = 100 °C/W when mounted on 0.2" × 0.2" copper pads - better than SMA (RθJA ≈ 140 °C/W) but higher than SMC (RθJA ≈ 60 °C/W). This makes the P6SMB16CAHM3_B/H well-suited for moderate-power surge protection where board space is constrained but full SMC-level cooling is unnecessary.
Does P6SMB16CAHM3_B/H require external biasing or control circuitry to function?
No, the P6SMB16CAHM3_B/H is a passive, two-terminal device that operates autonomously - it conducts only when voltage exceeds its breakdown threshold (15.2–16.8 V), clamping transients without any external power, timing, or control signals. Its function is purely voltage-dependent, making integration simple and failure modes predictable.
