Product details
Overview
P6SMB16CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 16 V standoff voltage (VWM), 18.2 V breakdown voltage (VBR min), and 22.5 V clamping voltage (VC) at 26.7 A peak pulse current (IPPM), delivering 600 W peak pulse power with 10/1000 μs waveform for circuit protection in automotive and industrial sensor interfaces.
For engineers reviewing the P6SMB16CAHE3_B/H datasheet, P6SMB16CAHE3_B/H pinout, P6SMB16CAHE3_B/H application, or P6SMB16CAHE3_B/H equivalent, key selection criteria include bidirectional surge clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.24), MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity dependency. It features glass-passivated junction technology for stable leakage performance and low incremental surge resistance, ensuring consistent clamping under repetitive 0.01% duty-cycle surges.
Thermal design relies on RθJA = 100 °C/W (junction-to-ambient, typical) and RθJL = 20 °C/W (junction-to-lead), with maximum junction temperature limited to +150 °C. Its response time is sub-nanosecond, and it meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13.6 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 15.2–16.8 V at 1 mA - Voltage at which device transitions into avalanche conduction; ensures predictable turn-on threshold. |
| VC (Clamping Voltage) | 22.5 V at 26.7 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Maximum transient energy absorption capability per 10/1000 μs waveform; enables robust ESD and load-dump immunity. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance lines. |
| TJ max | +150 °C - Maximum junction temperature rating supports operation in under-hood automotive and industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock per AEC standard. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Provides symmetrical conduction path for both positive and negative surges; connects to protected line or ground reference. |
| Cathode | Transient return path (bidirectional) | Electrically identical to Anode in CA-type devices; forms dual-junction structure enabling bidirectional clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns. |
| 600 W peak pulse power (10/1000 μs) | Withstands high-energy transients such as ISO 7637-2 Load Dump Pulse 5a (up to 120 V, 100 ms) when used with appropriate series impedance. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive electronics including engine control units, ADAS sensors, and body control modules requiring long-term field reliability. |
| MSL Level 1, 260 °C reflow compatible | Supports lead-free reflow soldering without preconditioning; eliminates moisture-related popcorning risk during assembly. |
| Glass-passivated junction | Ensures stable VBR tolerance and low leakage across temperature (-65 °C to +150 °C), critical for precision analog front-ends. |
Applications

IC Role / Device Role / Timing Role: First-stage protector mounted at line entry, coordinated with gas discharge tube (GDT) and series impedance for staged energy handling. Use Value: 600 W PPPM rating handles initial surge energy; 22.5 V clamping protects downstream hybrid transformers and line drivers rated for ≤30 V abs max. |
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 | Same VWM (13.6 V), VC = 24.4 V at 24.5 A; lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients; less suitable for automotive load dump where 600 W headroom is required. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-5 Level 3 (0.5 kV). |
| 1.5KE16CA | Same VWM/VC specs but through-hole DO-201 package; higher thermal mass but incompatible with SMT-only lines. | Not suitable for automated high-volume PCB assembly; requires wave solder or hand-solder rework. | Choose only for legacy repair, prototyping, or mixed-technology boards where SMT-only constraint does not apply. |
Compared with SMAJ16CA and 1.5KE16CA, P6SMB16CAHE3_B/H delivers superior surge handling (600 W vs. 400 W/1500 W), AEC-Q101 qualification for automotive use, and optimized SMT manufacturability-making it the preferred choice for new designs targeting IPC-A-610 Class 3 or automotive production.

FAQ
What is the clamping voltage of P6SMB16CAHE3_B/H at its rated peak pulse current?
The P6SMB16CAHE3_B/H has a maximum clamping voltage (VC) of 22.5 V at 26.7 A peak pulse current (IPPM), measured using the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2, electrical characteristics table for P6SMB16CA.
Is P6SMB16CAHE3_B/H suitable for automotive applications?
Yes, P6SMB16CAHE3_B/H is AEC-Q101 qualified, as indicated by the "HE3" and "_B" suffixes in the part number, confirming compliance with stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock. It is explicitly recommended for automotive sensor units, infotainment interfaces, and body electronics per Vishay's application notes and ordering information table.
How does the bidirectional configuration of P6SMB16CAHE3_B/H affect its circuit placement?
The bidirectional nature of P6SMB16CAHE3_B/H means it has no cathode marking and functions identically in either orientation-ideal for protecting AC-coupled or floating signal lines like CAN H/L or RS-485 A/B. Unlike unidirectional TVS diodes, P6SMB16CAHE3_B/H requires no polarity alignment during placement, simplifying layout and reducing assembly errors in differential or symmetrical interfaces.
What is the thermal resistance profile of P6SMB16CAHE3_B/H, and how does it impact PCB layout?
P6SMB16CAHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under sustained 5.0 W power dissipation, designers must provide adequate copper area and avoid excessive trace length between device terminals and thermal planes.
Does P6SMB16CAHE3_B/H meet RoHS and halogen-free requirements?
Yes, P6SMB16CAHE3_B/H is RoHS-compliant and AEC-Q101 qualified, with the "HE3" suffix denoting RoHS-compliant plating and material content. It is not halogen-free-that designation applies only to "HM3" variants. The device meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability standards, as documented in the Vishay P6SMB Series datasheet section "Mechanical Data".
