Product details
Overview
P6SMB16CAHE3_A/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. It is AEC-Q101 qualified and RoHS-compliant, targeting automotive and industrial electronics protection.
For engineers reviewing the P6SMB16CAHE3_A/I datasheet, P6SMB16CAHE3_A/I pinout, P6SMB16CAHE3_A/I application, or P6SMB16CAHE3_A/I equivalent, key selection criteria include bidirectional clamping performance, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
This bidirectional TVS diode operates symmetrically across both polarities, with identical breakdown (VBR min/max = 15.2–16.8 V at IT = 1 mA) and clamping characteristics in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
Designed for surface-mount assembly on standard PCB pads (0.2" × 0.2"), it delivers 600 W peak pulse power under repetitive 0.01% duty cycle conditions and supports operating junction temperatures from –65 °C to +150 °C. The device meets MSL Level 1 per J-STD-020 and is rated for lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13.6 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 15.2–16.8 V at 1 mA - Confirmed voltage range where device transitions from high-impedance to low-impedance clamping state. |
| VC (Clamping Voltage) | 22.5 V at IPPM = 26.7 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capacity under standardized 10/1000 μs surge waveform; enables robust system-level surge immunity. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Minimal standby current ensures negligible power loss and signal integrity in high-impedance circuits. |
| TJ max. | +150 °C - Maximum junction temperature rating supports operation in under-hood automotive and industrial environments. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient air; informs required PCB copper area and layout for thermal management. |

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; unsuitable for IEC 61000-4-5 Level 3+ without derating. | Select when board space is constrained and surge threat level is limited to ESD/lightning-induced coupling only. |
| SMCJ16CA | Same VWM (13.6 V), VC = 22.5 V at 26.7 A; higher PPPM (1500 W); larger SMC package (DO-214AB). | Overqualified for most automotive sensor lines; requires larger PCB pad area and higher mounting torque. | Choose when protecting high-power subsystems (e.g., motor drivers) requiring >1 kW surge handling and extended thermal margin. |

FAQ
What is the clamping voltage of P6SMB16CAHE3_A/I at its rated peak pulse current?
The P6SMB16CAHE3_A/I has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current (IPPM) of 26.7 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB16CAHE3_A/I maintains this clamping performance across its full operating temperature range (–65 °C to +150 °C).
Is P6SMB16CAHE3_A/I suitable for automotive applications?
Yes, P6SMB16CAHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliant and AEC-Q101 qualified construction. It meets stress test requirements including temperature cycling, highly accelerated stress testing (HAST), and mechanical shock per JESD22 standards. The P6SMB16CAHE3_A/I is commonly deployed in engine control units, body electronics, and ADAS sensor modules where transient immunity and long-term reliability are critical.
What does the "CA" suffix indicate in P6SMB16CAHE3_A/I?
The "CA" suffix in P6SMB16CAHE3_A/I denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB16A), the P6SMB16CAHE3_A/I has no polarity marking and functions identically regardless of applied voltage polarity. This makes it ideal for protecting AC-coupled lines, differential buses like CAN or RS-485, and any signal path subject to bipolar transients.
What is the thermal resistance of P6SMB16CAHE3_A/I, and how does it affect PCB layout?
The P6SMB16CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value directly impacts PCB thermal design: to maintain TJ ≤ 150 °C under 5.0 W steady-state dissipation, ≥100 mm² of 2-oz copper per pad is recommended. Layout must avoid thermal isolation-ground planes should connect directly to both terminals via multiple vias to minimize thermal impedance.
How does P6SMB16CAHE3_A/I compare to unidirectional P6SMB16AHE3_A/I in terms of electrical behavior?
The P6SMB16CAHE3_A/I and P6SMB16AHE3_A/I share identical VWM (13.6 V), VBR (15.2–16.8 V), VC (22.5 V), and PPPM (600 W) ratings-but differ fundamentally in polarity response. The P6SMB16CAHE3_A/I conducts surge current in both directions with matched clamping, while the P6SMB16AHE3_A/I only clamps in reverse bias and conducts forward current like a rectifier. Thus, P6SMB16CAHE3_A/I is mandatory for AC or differential signal protection, whereas P6SMB16AHE3_A/I suits DC power rail protection where polarity is fixed.
