Product details
Overview
P6SMB130CAHM3_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 130 V standoff voltage (VWM), 149 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 3.4 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 industrial and automotive electronics.
For engineers reviewing the P6SMB130CAHM3_A/I datasheet, P6SMB130CAHM3_A/I pinout, P6SMB130CAHM3_A/I application, or P6SMB130CAHM3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, SMB (DO-214AA) package compatibility, thermal resistance (RθJA = 100 °C/W), and compliance with J-STD-020 MSL level 1 reflow profile.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity sensitivity. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time (<1.0 ps), critical for suppressing ESD and lightning-induced surges before downstream components are damaged.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; it delivers 600 W peak pulse power only when mounted on 0.2" × 0.2" copper pads per JEDEC standard test conditions. Its halogen-free, RoHS-compliant HM3 suffix confirms compliance with JESD201 Class 2 whisker resistance and LF peak reflow up to 260 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Same VWM (111 V), identical SMB package, but not AEC-Q101 qualified; higher VC (224 V) and lower IPPM (3.3 A). | Limited to commercial/industrial use; unsuitable for automotive production where AEC-Q101 is mandatory. | Select SMBJ130CA only if AEC-Q101 is not required and cost is prioritized over automotive qualification. |
| 1.5SMC130CA | Higher power rating (1500 W), larger SMC (DO-214AB) package, same VWM/VC specs; RθJA = 40 °C/W vs. 100 °C/W. | Requires more PCB area and different pad layout; better suited for high-energy surge zones like AC mains entry. | Choose 1.5SMC130CA when system-level surge tests exceed 600 W or thermal constraints demand lower junction rise. |
Compared with SMBJ130CA and 1.5SMC130CA, P6SMB130CAHM3_A/I uniquely balances AEC-Q101 qualification, SMB footprint constraints, and 600 W surge capability - making it optimal for space-constrained automotive and industrial modules where qualification and layout compatibility are non-negotiable.

FAQ
What does the "CA" suffix indicate in P6SMB130CAHM3_A/I?
The "CA" suffix in P6SMB130CAHM3_A/I denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage clamping in both polarities. This eliminates the need for polarity-aware placement on PCBs and makes it ideal for protecting AC-coupled or differential signal lines such as RS-485, CAN, or audio interfaces. Unlike unidirectional variants (e.g., P6SMB130A), P6SMB130CAHM3_A/I has no cathode band marking and conducts equally in either direction.
Is P6SMB130CAHM3_A/I suitable for automotive applications?
Yes, P6SMB130CAHM3_A/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and Vishay's documentation. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev G. This qualification validates its use in automotive subsystems such as body control modules, infotainment interfaces, and sensor signal conditioning where reliability under thermal and electrical stress is mandatory.
What is the maximum clamping voltage of P6SMB130CAHM3_A/I and how is it measured?
The maximum clamping voltage (VC) of P6SMB130CAHM3_A/I is 219 V, measured at a peak pulse current (IPPM) of 3.4 A using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed per Vishay's datasheet (Document Number 88370, page 2) and reflects the worst-case voltage imposed on the protected circuit during a surge event - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings.
How does the HM3 suffix differ from E3 or M3 in P6SMB130CAHM3_A/I?
The HM3 suffix in P6SMB130CAHM3_A/I 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). HM3 devices meet JESD201 Class 2 whisker resistance and are rated for 260 °C peak reflow, making them suitable for automotive production where both environmental compliance and reliability certification are required.
Can P6SMB130CAHM3_A/I be used in place of P6SMB130A in a design?
No - P6SMB130CAHM3_A/I is bidirectional, while P6SMB130A is unidirectional and features a cathode band for polarity identification. Substituting them without circuit review risks incorrect clamping behavior on DC-biased lines. The unidirectional version conducts forward current during positive surges only; the bidirectional P6SMB130CAHM3_A/I clamps both polarities. Layout, grounding strategy, and system-level surge testing must be revalidated if switching between these configurations.
