Product details
Overview
P6SMB110CAH from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with breakdown voltage range 105–116 V, clamping voltage 152 V at 4.1 A peak pulse current, and stand-off voltage 94.0 V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB110CAH datasheet, P6SMB110CAH pinout, P6SMB110CAH application, or P6SMB110CAH equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 55 °C/W), moisture sensitivity level (MSL 1), and bidirectional clamping behavior critical for ESD and load-dump protection design.
Technical Context
The P6SMB110CAH is a glass-passivated, bipolar junction TVS diode optimized for fast transient suppression in 12 V/24 V automotive systems. Its 10/1000 µs waveform rating of 600 W and sub-1 ps response time enable reliable clamping of high-energy spikes without degradation under repetitive stress.
Designed for bidirectional operation, it exhibits symmetrical breakdown (VBR min/max = 105/116 V) and identical clamping performance in both polarities. Its RθJC = 10 °C/W and RθJA = 55 °C/W support thermal management in compact PCB layouts with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V - Ensures consistent triggering above system nominal voltage while accommodating manufacturing tolerance |
| VWM | 94.0 V - Maximum continuous reverse operating voltage; sets safe margin below breakdown for 24 V automotive systems |
| VC @ IPPM | 152 V at 4.1 A - Clamped voltage during 10/1000 µs surge; defines worst-case overvoltage seen by protected IC |
| PPPSM | 600 W - Peak pulse power handling per single 10/1000 µs event; meets ISO 7637-2 Pulse 5a requirements |
| IR @ VWM | <1 µA - Ultra-low leakage ensures negligible standby current drain in battery-critical applications |
| TJ max | +150 °C - Enables operation in under-hood environments without derating in most mounting configurations |
| Package | DO-214AA (SMB) - Standardized surface-mount footprint compatible with automated assembly and IPC-7351B land patterns |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band (bidirectional operation uses symmetric marking; no functional anode/cathode distinction).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (marked end) | Transient return path (bidirectional) | Functions identically as cathode; terminal symmetry enables placement without orientation constraints |
| Cathode (marked end) | Transient return path (bidirectional) | Same electrical role as anode; marking denotes polarity reference only, not unidirectional conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114 |
| Glass passivated junction | Eliminates wire bond corrosion risk and improves long-term stability under humidity and thermal stress |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) without parametric shift |
| MSL 1 rating | Zero floor life limitation; supports unlimited exposure to ambient conditions prior to reflow soldering |
| Halogen-free & RoHS | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally compliant production |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VBR range (105–116 V), identical DO-214AA package, but rated at 600 W with slightly higher VC (156 V @ 4.0 A) | Marginally lower clamping ratio; may require layout review if system has tight overvoltage headroom | Select SMBJ110CA only if existing design uses SMBJ-series footprints and thermal validation confirms RθJA compatibility |
| 1.5KE110CA | Higher power rating (1500 W), axial DO-15 package, VBR 105–116 V, VC 177 V @ 8.5 A | Not surface-mountable; requires through-hole assembly and larger board area; unsuitable for automated SMT lines | Choose 1.5KE110CA only for prototyping or low-volume legacy repair where DO-214AA footprint is unavailable |
Compared with SMBJ110CA and 1.5KE110CA, the P6SMB110CAH offers optimal balance of AEC-Q101 qualification, MSL 1 handling, and SMB footprint density-making it preferred for volume automotive and industrial SMT production where reliability and manufacturability are jointly prioritized.

FAQ
What does the 'CAH' suffix indicate in P6SMB110CAH?
The 'CAH' suffix in P6SMB110CAH denotes a bidirectional configuration (C), AEC-Q101 qualification (A), and halogen-free construction (H). This distinguishes it from unidirectional 'H' variants and non-automotive 'AH' versions. The P6SMB110CAH provides symmetrical clamping in both polarities, making it ideal for AC-coupled or floating bus protection where polarity reversal is possible.
Does P6SMB110CAH meet ISO 7637-2 requirements?
Yes, the P6SMB110CAH is explicitly rated to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test waveforms. Its 600 W peak pulse power rating and 152 V clamping voltage at 4.1 A ensure compliance when implemented with proper PCB layout (e.g., short traces, ground plane coupling). The P6SMB110CAH datasheet confirms this in the FEATURES section and Electrical Specifications table.
What is the maximum junction temperature for P6SMB110CAH?
The maximum junction temperature (TJ) for P6SMB110CAH is +150 °C, as specified in the Absolute Maximum Ratings table. This allows operation in under-hood automotive environments and high-ambient industrial settings without thermal derating, provided the device's RθJA = 55 °C/W is respected via adequate copper pour and airflow. The P6SMB110CAH maintains stable VBR and leakage performance across its full –55 °C to +150 °C operating range.
Is P6SMB110CAH suitable for automated SMT assembly?
Yes, the P6SMB110CAH is designed for automated surface-mount placement. Its DO-214AA (SMB) package features matte tin-plated leads compliant with J-STD-002 solderability standards, low profile geometry, and MSL 1 moisture sensitivity rating-enabling direct placement into reflow ovens without baking. The P6SMB110CAH's standardized footprint and polarity marking simplify vision-based alignment in high-speed pick-and-place systems.
How does P6SMB110CAH differ from P6SMB110AH?
The P6SMB110CAH is bidirectional (C), while P6SMB110AH is unidirectional (no C). Both share identical VBR (105–116 V), VWM (94.0 V), and VC (152 V) ratings, but the P6SMB110CAH clamps transients equally in forward and reverse bias, whereas P6SMB110AH only protects against reverse-polarity surges. Use P6SMB110CAH when protecting AC lines, differential buses, or circuits subject to voltage reversals; use P6SMB110AH for DC rails with fixed polarity.
