Product details
Overview
P6SMB16CAHE3/5B 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 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current. It delivers 600 W peak pulse power (10/1000 μs), supports automotive-grade AEC-Q101 qualification, and protects signal lines in sensor units and MOSFET gate drivers.
For engineers reviewing the P6SMB16CAHE3/5B datasheet, P6SMB16CAHE3/5B pinout, P6SMB16CAHE3/5B application, or P6SMB16CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM = 1.41), AEC-Q101 qualification status, SMB package thermal resistance (RθJA = 100 °C/W), and compliance with J-STD-020 MSL Level 1 reflow profile.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports rapid energy dissipation during ESD or lightning-induced transients.
The device is rated for repetitive 10/1000 μs waveform pulses at 0.01% duty cycle and derates linearly above 25 °C ambient per Fig. 2. Junction temperature remains within safe limits up to +150 °C, and its matte tin-plated leads comply with J-STD-002 solderability standards.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA | 400 W peak pulse power (vs. 600 W); SMA package (higher RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for industrial 24 V I/O with frequent inductive switching | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 Level 4 ESD only |
| 1.5KE16CA | Through-hole DO-201 package; same 600 W rating but larger footprint and manual assembly requirement | Not compatible with automated SMT lines; unsuitable for high-density consumer PCBs | Choose for legacy repair, prototyping, or cost-sensitive non-automated production where reflow compatibility is not required |
Compared with SMAJ16CA and 1.5KE16CA, P6SMB16CAHE3/5B offers superior power density (600 W in SMB), AEC-Q101 qualification for automotive use, and MSL Level 1 process compatibility-making it optimal for volume SMT production of ruggedized electronics requiring repeatable surge immunity.

FAQ
What is the clamping voltage of P6SMB16CAHE3/5B at its rated peak pulse current?
The P6SMB16CAHE3/5B has a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current (IPPM) of 26.7 A, measured using a 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB16CAHE3/5B maintains this clamping performance with low incremental resistance, ensuring predictable protection behavior even under repeated stress.
Is P6SMB16CAHE3/5B suitable for automotive applications?
Yes, P6SMB16CAHE3/5B is AEC-Q101 qualified, as indicated by the "HE3" suffix, and is explicitly rated for automotive use in environments such as engine control units, body electronics, and ADAS sensor interfaces. Its construction meets JESD201 Class 2 whisker resistance, MSL Level 1 reflow compatibility, and operates reliably from −65 °C to +150 °C. The P6SMB16CAHE3/5B datasheet confirms qualification testing per AEC-Q101 Rev D requirements.
How does the bidirectional configuration of P6SMB16CAHE3/5B affect its circuit placement?
The bidirectional configuration of P6SMB16CAHE3/5B means it functions identically regardless of voltage polarity, eliminating the need for orientation-specific placement on PCBs. Unlike unidirectional TVS diodes, P6SMB16CAHE3/5B has no cathode band marking and can be installed across any two points requiring symmetrical overvoltage protection-such as differential data lines (RS-485, CAN), AC signal paths, or floating sensor outputs-without concern for anode/cathode alignment.
What is the standoff voltage (VWM) of P6SMB16CAHE3/5B, and why is it important?
The standoff voltage (VWM) of P6SMB16CAHE3/5B is 13.6 V, representing the maximum continuous reverse voltage the device can block without entering avalanche conduction. This parameter ensures the P6SMB16CAHE3/5B remains non-conductive during normal operation of a 12 V nominal system, preventing leakage-related power loss or false triggering. Selecting VWM ≥110% of the system's maximum steady-state voltage avoids nuisance conduction while retaining sufficient margin for transients.
Does P6SMB16CAHE3/5B require special PCB layout considerations for thermal management?
Yes, P6SMB16CAHE3/5B requires 5.0 mm × 5.0 mm copper pads per terminal (as specified in the datasheet) to achieve its rated 600 W peak pulse power and 5.0 W steady-state power dissipation. Smaller pads increase thermal resistance, causing junction temperature to exceed +150 °C during surge events and risking parametric shift or failure. The P6SMB16CAHE3/5B thermal resistance (RθJA) is 100 °C/W under these conditions-reducing pad size raises RθJA disproportionately and invalidates published ratings.
