Product details
Overview
P6SMB16CAHE3_B/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 or power lines. It features a 16 V standoff voltage (VWM), 22.5 V maximum clamping voltage at 26.7 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial systems.
For engineers reviewing the P6SMB16CAHE3_B/I datasheet, P6SMB16CAHE3_B/I pinout, P6SMB16CAHE3_B/I application, or P6SMB16CAHE3_B/I equivalent, key selection criteria include bidirectional transient suppression capability, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and clamping performance under repetitive surge conditions.
Technical Context
This bidirectional TVS diode operates symmetrically across both polarities, delivering consistent clamping behavior during positive and negative transients without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at 13.6 V), while the low incremental surge resistance supports fast energy diversion.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak. Its thermal resistance (RθJA = 100 °C/W) reflects standard SMB mounting on 5.0 mm × 5.0 mm copper pads, enabling reliable operation in high-reliability automotive ECUs and industrial I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 13.6 V - maximum continuous reverse working voltage before clamping begins |
| Breakdown Voltage (VBR) | 15.2–16.8 V at 1.0 mA test current - defines onset of avalanche conduction |
| Clamping Voltage (VC) | 22.5 V at 26.7 A IPPM - peak voltage seen by protected circuit during 10/1000 μs surge |

Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Bidirectional construction means no cathode/anode marking; terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode / Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; no polarity marking required |
| Terminal 2 | Anode / Cathode (bidirectional) | Electrically identical to Terminal 1; enables symmetrical clamping in AC or floating signal paths |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables robust protection against ISO 7637-2 pulse 1, 2a, 3a/b, and IEC 61000-4-5 surges in automotive electronics |
| AEC-Q101 qualification (HE3 suffix) | Validates reliability for under-hood and chassis-mounted automotive modules requiring extended temperature and life-cycle validation |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage stress on downstream ICs during ESD or load-dump events |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free SMT assembly without pre-baking or special handling |
| Glass passivated junction | Ensures stable leakage current (<1 μA) and long-term parameter stability across temperature and humidity |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor signal lines (e.g., pressure, temperature) from inductive switching transients and ESD in engine control units. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector or IC input pins to limit transient excursions below IC absolute maximum ratings. Use Value: Prevents latch-up or gate oxide damage in microcontrollers and analog front-ends during 100 V/μs fast transients, enabled by 22.5 V clamping at 26.7 A. |
Use Scenario: Safeguarding 24 V digital input channels in programmable logic controllers exposed to relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Primary transient suppressor on field-side traces, mounted adjacent to screw-terminal blocks before optocoupler or Schmitt-trigger inputs. Use Value: Absorbs up to 600 W surge energy without degradation, maintaining channel integrity during repeated 1 kV/500 A surge events per IEC 61000-4-5. |
| Consumer Power Adapter Output Clamping | Telecom Line Card Surge Protection |
Use Scenario: Clamping output rail overshoot in AC/DC adapters during startup or short-circuit recovery, especially where secondary-side synchronous rectifiers are used. IC Role / Device Role / Timing Role: Secondary-side TVS placed between VOUT and GND to suppress ringing and transformer leakage spikes. Use Value: Fast response (<1 ns) and low clamping voltage prevent false triggering or overvoltage shutdown in PMICs monitoring output rails. |
Use Scenario: Protecting Ethernet PHY or DSL line drivers from lightning-induced surges entering via RJ-45 jacks in network interface cards. IC Role / Device Role / Timing Role: First-stage protector on differential pairs, paired with common-mode chokes and gas discharge tubes for multi-level defense. Use Value: Symmetrical bidirectional clamping ensures equal protection on both conductors, preserving signal integrity during ±1 kV contact ESD per IEC 61000-4-2. |
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 (smaller footprint, higher RθJA) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when board space is constrained and automotive qualification is unnecessary |
| 1.5KE16CA | Through-hole DO-201 package, same 16 V VWM and 22.5 V VC, but 1.5 kW rating | Higher surge margin but incompatible with SMT-only assembly; larger PCB footprint | Choose for legacy through-hole designs or where 1.5 kW single-pulse immunity is mandatory |
Compared with SMAJ16CA and 1.5KE16CA, P6SMB16CAHE3_B/I delivers optimal balance of 600 W surge capability, AEC-Q101 compliance, and SMB package manufacturability - making it preferred for new automotive and industrial SMT designs requiring validated reliability and process compatibility.

FAQ
What does the "CA" suffix indicate in P6SMB16CAHE3_B/I?
The "CA" suffix denotes a bidirectional configuration: P6SMB16CAHE3_B/I clamps voltage transients equally in both polarities, making it suitable for AC-coupled or floating signal lines where polarity is undefined. Unlike unidirectional variants (e.g., P6SMB16A), it has no cathode marking and exhibits symmetric VBR and VC characteristics in either direction - confirmed in the Electrical Characteristics table on page 2 of Vishay document 88370.
Is P6SMB16CAHE3_B/I suitable for automotive applications?
Yes, P6SMB16CAHE3_B/I is AEC-Q101 qualified, as indicated by the "HE3" suffix and documented in the Ordering Information section (page 3) of Vishay's P6SMB datasheet. It undergoes stress testing for temperature cycling, humidity bias, and mechanical shock per AEC-Q101 standards, and is explicitly recommended for automotive sensor units and ECUs in the Typical Applications section.
What is the maximum clamping voltage of P6SMB16CAHE3_B/I and under what test condition?
The maximum clamping voltage of P6SMB16CAHE3_B/I is 22.5 V, measured at a peak pulse current (IPPM) of 26.7 A using a 10/1000 μs double-exponential waveform - per the Electrical Characteristics table on page 2 of Vishay document 88370. This value represents the worst-case voltage imposed on protected circuitry during standardized surge events.
How does the SMB (DO-214AA) package of P6SMB16CAHE3_B/I compare to SMA or SMC packages?
The SMB package of P6SMB16CAHE3_B/I measures 5.59 mm × 4.06 mm × 2.20 mm, offering higher power handling than SMA (DO-214AC) and smaller footprint than SMC (DO-214AB). Its 100 °C/W junction-to-ambient thermal resistance assumes 5.0 mm × 5.0 mm copper pads - verified in the Thermal Characteristics table - making it ideal for dense layouts where 600 W surge capability must coexist with compact size.
Does P6SMB16CAHE3_B/I require derating at elevated ambient temperatures?
Yes, P6SMB16CAHE3_B/I requires derating above TA = 25 °C, as shown in Figure 2 of Vishay document 88370. Its peak pulse power capability decreases linearly: at 85 °C ambient, PPPM drops to ~70 % of rated 600 W. Designers must apply this derating when deploying P6SMB16CAHE3_B/I in under-hood or enclosed industrial enclosures where sustained high ambient temperatures occur.
