Product details
Overview
P6SMB11CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 9.4 V stand-off voltage (VWM), 15.6 V maximum clamping voltage (VC) at 5.0 A peak pulse current, and 600 W peak pulse power capability with 10/1000 µs waveform - ideal for protecting MOSFETs and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB11CAHM3_A/H datasheet, P6SMB11CAHM3_A/H pinout, P6SMB11CAHM3_A/H application, or P6SMB11CAHM3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–65 to +150 °C), and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both directions due to its bidirectional construction. Its glass-passivated junction ensures stable leakage performance (<5.0 µA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The P6SMB11CAHM3_A/H is rated for 600 W peak pulse power under 10/1000 µs waveform at 0.01% duty cycle, with derating above 25 °C ambient per Fig. 2. Its thermal design relies on 0.2" × 0.2" copper pads per terminal, achieving RθJL = 20 °C/W and supporting repetitive surge handling in automotive-grade environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 9.4 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 10.5–11.6 V at 1.0 mA - Verified breakdown threshold ensuring predictable turn-on during transients. |
| VC (Clamping) | 15.6 V at 5.0 A IPPM - Peak voltage seen by protected circuit during worst-case 10/1000 µs surge. |
| PPPM | 600 W - Sustained transient energy absorption capacity without failure under standardized surge waveform. |
| TJ max. | +150 °C - Maximum junction temperature enabling operation in under-hood automotive and high-ambient industrial settings. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11CA | Same VWM (9.4 V) and VC (15.6 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for automotive load-dump scenarios requiring 600 W rating | Select when board space is constrained and surge threat level is limited to IEC 61000-4-4 Level 3. |
| 1.5KE11CA | Higher PPPM (1500 W), through-hole DO-201 package; larger size, slower mounting, higher parasitic inductance | Better for high-energy primary-side protection but incompatible with automated SMT lines and dense PCB layouts | Choose only for legacy through-hole designs or where 1500 W headroom justifies manual assembly and layout overhead. |
Compared with SMAJ11CA and 1.5KE11CA, the P6SMB11CAHM3_A/H uniquely balances 600 W surge capability, AEC-Q101 qualification, halogen-free compliance, and SMB package compatibility with high-speed SMT lines - making it optimal for next-generation automotive and industrial edge devices.

FAQ
What does the "CA" suffix indicate in P6SMB11CAHM3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB11CAHM3_A/H provides symmetrical transient voltage clamping in both polarities. This eliminates orientation sensitivity during placement and ensures consistent protection for AC-coupled or differential signal paths - unlike unidirectional variants (e.g., P6SMB11AHM3_A/H) that require correct cathode alignment.
Is P6SMB11CAHM3_A/H qualified for automotive use?
Yes, P6SMB11CAHM3_A/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix and Vishay documentation. It has passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), making it suitable for under-hood and chassis-mounted automotive electronics where reliability under thermal and mechanical stress is critical.
What is the maximum clamping voltage of P6SMB11CAHM3_A/H and at what current is it specified?
The maximum clamping voltage (VC) of P6SMB11CAHM3_A/H is 15.6 V, measured at a peak pulse current (IPPM) of 5.0 A under the standard 10/1000 µs waveform. This value represents the highest voltage the protected circuit will experience during a defined surge event, directly informing system-level overvoltage margin design.
How does the HM3 suffix differ from E3 or M3 in P6SMB11CAHM3_A/H?
The "HM3" suffix indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from "E3" (RoHS-compliant commercial grade) and "M3" (halogen-free RoHS-compliant commercial grade). Only HM3 and HE3 variants carry automotive qualification, and HM3 specifically meets JESD201 Class 2 whisker resistance requirements for long-term solder joint integrity.
Can P6SMB11CAHM3_A/H be used in place of P6SMB11A or P6SMB11CA with different suffixes?
P6SMB11CAHM3_A/H is functionally compatible with other P6SMB11CA variants in terms of electrical parameters, but substitution requires verification of qualification level and material compliance. Unlike commercial-grade P6SMB11CA-E3/M3, the HM3 version adds AEC-Q101 qualification and halogen-free content - essential for automotive designs but not required for general industrial use.
