Product details
Overview
P6SMB10CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, and 10 V standoff voltage - deployed for ESD and surge protection on automotive sensor signal lines, industrial I/O ports, and telecom interface circuits.
For engineers reviewing the P6SMB10CAHM3/I datasheet, P6SMB10CAHM3/I pinout, P6SMB10CAHM3/I application, or P6SMB10CAHM3/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, 100 °C/W junction-to-ambient thermal resistance, low 1.0 μA reverse leakage at VWM, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding its 10 V standoff voltage, it avalanches symmetrically in both directions to clamp the line at ≤14.5 V while diverting up to 41.4 A (10/1000 μs). Its glass-passivated junction ensures stable breakdown and fast sub-nanosecond response.
Designed for surface-mount automated assembly, the device meets J-STD-020 MSL Level 1 (260 °C peak reflow), supports 150 °C maximum junction temperature, and delivers 5.0 W steady-state power dissipation on infinite heatsink at 50 °C ambient - enabling use in thermally constrained PCB layouts without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains single high-energy transients common in automotive load-dump or inductive switching events |
| Standoff Voltage (VWM) | 10 V - defines maximum continuous operating voltage before conduction begins in either direction |
| Clamping Voltage (VC) | 14.5 V at 41.4 A - limits protected circuit voltage during worst-case surge, ensuring downstream ICs remain within safe operating area |
| Breakdown Voltage (VBR) | 10.5 V min / 11.6 V max at 1 mA - guarantees tight tolerance for precise overvoltage threshold setting |
| Reverse Leakage (ID) | 1.0 μA at 10 V - negligible standby current, critical for low-power sensor and battery-backed systems |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in under-hood automotive and industrial environments |

Use Value: Symmetrical 10 V standoff and 14.5 V clamping ensure balanced noise rejection and prevent data corruption during 1 kV/μs transients. |
Use Scenario: Adding secondary-level surge immunity to USB 2.0 D+/D− lines in smart home hubs after primary protection at the connector. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF typical) bidirectional clamp minimizing signal distortion on 480 Mbps data paths. Use Value: 1.0 μA leakage at 10 V avoids pull-up/pull-down interference - maintains USB enumeration reliability and VBUS detection accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same 10 V VWM and bidirectional configuration, but 400 W PPPM rating and SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a (load dump) due to lower power rating | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2/4-4 only |
| 1.5KE10CA | Through-hole DO-201 package, 1500 W PPPM, same 10 V VWM - but larger size, higher parasitic inductance, and no AEC-Q101 qualification | Not suitable for automated SMT lines or automotive under-hood environments requiring vibration resistance and thermal cycling validation | Choose for prototyping or legacy through-hole designs where high pulse energy must be absorbed and reflow compatibility is not required |
Compared with SMAJ10CA and 1.5KE10CA, P6SMB10CAHM3/I uniquely balances 600 W surge capability, AEC-Q101 qualification, SMB footprint compatibility, and halogen-free compliance - making it optimal for volume automotive and industrial SMT production where reliability, manufacturability, and regulatory alignment are jointly critical.

FAQ
What is the clamping voltage of P6SMB10CAHM3/I at its rated peak pulse current?
The P6SMB10CAHM3/I has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current (IPPM) 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 - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6SMB10CAHM3/I qualified for automotive applications?
Yes, P6SMB10CAHM3/I is AEC-Q101 qualified, as confirmed by the HM3 suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024, Doc. #88370). It undergoes stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification - making it suitable for use in engine control units, ADAS sensors, and body electronics where automotive-grade reliability is mandatory.
What does the "CA" suffix indicate in P6SMB10CAHM3/I?
The "CA" suffix in P6SMB10CAHM3/I denotes a bidirectional configuration: the device provides symmetrical transient suppression in both forward and reverse directions, with identical electrical characteristics (VWM, VBR, VC) regardless of voltage polarity. This eliminates the need for orientation-aware placement and simplifies design for AC-coupled or differential signal lines such as RS-485 or CAN bus.
How does the HM3 suffix differ from E3 or M3 in P6SMB10CAHM3/I?
The HM3 suffix in P6SMB10CAHM3/I indicates halogen-free, RoHS-compliant construction *and* AEC-Q101 qualification - distinguishing it from E3 (RoHS-compliant commercial grade) and M3 (halogen-free RoHS-compliant commercial grade). The "H" prefix explicitly signals automotive qualification, while "M3" confirms halogen-free molding compound and lead finish, meeting strict environmental and reliability requirements for Tier 1 automotive supply chains.
What is the thermal resistance of P6SMB10CAHM3/I, and how does it affect layout?
P6SMB10CAHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay document 88370. This value guides PCB layout: adequate copper pour area and thermal vias are required to maintain junction temperature below 150 °C during repetitive surge events - especially important in enclosed enclosures or high-ambient-temperature environments.
