Product details
Overview
P6SMB30CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 30 V standoff voltage (VWM), 33.3 V minimum breakdown voltage (VBR), 41.4 V maximum clamping voltage (VC) at 14.5 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB30CAHE3_A/H datasheet, P6SMB30CAHE3_A/H pinout, P6SMB30CAHE3_A/H application, or P6SMB30CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while low incremental surge resistance supports effective energy diversion during ESD or lightning-induced surges.
The device is rated for continuous operation from –65 °C to +150 °C junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) when mounted per recommended pad layout. Its 600 W peak pulse rating is specified under repetitive 0.01% duty cycle conditions with 10/1000 μs waveform, derated linearly above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 30 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 33.3 V min / 37.1 V max at 1 mA - Voltage at which device enters avalanche conduction; ensures reliable triggering above normal operating range. |
| VC (Clamping Voltage) | 41.4 V max at IPPM = 14.5 A - Peak voltage seen by protected circuit during transient; determines safe overvoltage margin for downstream components. |
| PPPM (Peak Pulse Power) | 600 W with 10/1000 μs waveform - Energy-handling capacity for transient suppression; enables robust protection against IEC 61000-4-5 surge events. |
| ID (Reverse Leakage) | 1.0 μA max at VWM = 30 V - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTOL, TC, and ESD; designated by HE3 suffix. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | Same SMB package, 30 V VWM, but rated for 600 W with 8.3 ms half-sine surge (not 10/1000 μs); higher IFSM (100 A) but no AEC-Q101 qualification. | Preferred for non-automotive industrial power-line protection where long-duration surges dominate. | Select SMBJ30CA if surge profile is primarily 8.3 ms line-frequency related rather than fast 10/1000 μs transients. |
| 1.5SMC33CA | Higher power (1500 W), same VWM/VBR/VC specs, but larger SMC (DO-214AB) package; not AEC-Q101 qualified. | Suitable where board space allows larger footprint and higher energy absorption is required beyond 600 W. | Choose 1.5SMC33CA only when system-level surge testing exceeds 600 W and PCB layout accommodates SMC dimensions. |
Compared with SMBJ30CA and 1.5SMC33CA, P6SMB30CAHE3_A/H uniquely combines AEC-Q101 qualification, MSL Level 1 compatibility, and precise 10/1000 μs waveform rating in the smallest SMB footprint - making it optimal for space-constrained automotive and high-reliability industrial designs requiring traceable qualification.

FAQ
What does the "CA" suffix indicate in P6SMB30CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning P6SMB30CAHE3_A/H provides symmetrical clamping in both polarities - essential for protecting AC-coupled signals, differential buses like CAN or RS-485, and floating sensor outputs without regard to voltage polarity during transients.
Is P6SMB30CAHE3_A/H suitable for automotive applications?
Yes, P6SMB30CAHE3_A/H is AEC-Q101 qualified (indicated by the "HE3" suffix) and tested for high-temperature operation up to +150 °C junction temperature. It meets automotive requirements for surge immunity, thermal cycling, and long-term reliability in engine control, body electronics, and ADAS sensor modules.
What is the clamping voltage of P6SMB30CAHE3_A/H at its rated peak pulse current?
The maximum clamping voltage (VC) of P6SMB30CAHE3_A/H is 41.4 V at a peak pulse current (IPPM) of 14.5 A, measured using the standard 10/1000 μs double-exponential waveform - defining the upper voltage limit imposed on protected circuits during transient events.
How does the SMB (DO-214AA) package of P6SMB30CAHE3_A/H compare to larger alternatives like SMC?
The SMB package of P6SMB30CAHE3_A/H measures 3.94 mm × 2.20 mm × 1.52 mm, offering 40% smaller footprint than SMC (DO-214AB). While SMC variants provide higher power ratings (e.g., 1500 W), P6SMB30CAHE3_A/H delivers optimal 600 W protection in space-constrained layouts common in automotive ECUs and portable industrial controllers.
Does P6SMB30CAHE3_A/H require special handling during PCB assembly?
No special handling is required: P6SMB30CAHE3_A/H is rated MSL Level 1 per J-STD-020 and withstands peak reflow temperatures up to 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, supporting standard lead-free reflow processes without pre-baking or dry-pack requirements.
