Product details
Overview
P6SMB16CH from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 14.4–17.6V, clamping voltage of 23.5V at 26A peak pulse current, and DO-214AA (SMB) package. It provides robust ESD and electrical fast transient protection for automotive lighting control modules, industrial sensor interfaces, and power supply input stages.
For engineers reviewing the P6SMB16CH datasheet, P6SMB16CH pinout, P6SMB16CH application, or P6SMB16CH equivalent, key selection criteria include its AEC-Q101 qualification, 1.0mA test current, <1μA reverse leakage at 12.9V stand-off, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and bidirectional clamping symmetry.
Technical Context
The P6SMB16CH is a unidirectional/bidirectional TVS diode configured as a single die in a glass-passivated junction structure. Its bidirectional operation (denoted by "CH" suffix) ensures symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal lines without polarity constraints.
It delivers 600W non-repetitive peak pulse power handling per 10/1000μs waveform, with thermal resistance RθJC = 10°C/W and RθJA = 55°C/W. The device operates across –55°C to +150°C junction temperature and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.4V / 17.6V - Ensures reliable turn-on above system operating voltage while avoiding false triggering |
| VWM | 12.9V - Maximum continuous reverse working voltage compatible with 12V nominal systems |
| VC@IPPM | 23.5V @ 26A - Clamps transients to safe levels for downstream 24V-rated ICs and MOSFETs |
| IPPM | 26A - Peak surge current capacity sufficient for ISO 7637-2 Pulse 1 (inductive load dump) events |
| PPPSM | 600W - High-energy absorption capability for automotive and industrial transient immunity |
| TJ max | +150°C - Enables use in under-hood and high-temperature PCB environments |
| Leakage @ VWM | <1μA - Negligible standby power loss and minimal impact on high-impedance sensing circuits |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, low-profile, matte tin-plated leads, cathode band marking for polarity identification (bidirectional variant uses symmetric marking per datasheet).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Cathode Band Side) | Transient current sink (reverse bias) | Acts as cathode in unidirectional mode; in bidirectional P6SMB16CH, functions identically in both directions due to symmetric construction |
| Cathode (Opposite Cathode Band) | Transient current sink (reverse bias) | Same clamping behavior as anode side - no functional distinction in CH-suffix devices; terminals are interchangeable for AC protection |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per JEDEC standards |
| Glass passivated junction | Enhances long-term stability and reduces parameter drift under thermal/humidity stress vs. epoxy-passivated alternatives |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive switch-off), Pulse 2a/2b (load dump coupling), and Pulse 3a/3b (capacitive coupling) immunity requirements |
| Fast response time | <1.0ps rise time from 0V to VBR(min) - Limits voltage overshoot before clamping engages |
| Moisture sensitivity level 1 | No bake preconditioning required before reflow - supports standard SMT assembly without special handling |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | Same DO-214AA package, identical VBR (14.4–17.6V), but rated for 600W with higher VC = 26.0V @ 23.5A | Higher clamping voltage reduces margin for 24V-rail ICs; lower IPPM (23.5A vs. 26A) limits surge headroom | Select when legacy design uses SMBJ footprint and tighter VC tolerance is not critical |
| 1.5KE16CA | Through-hole DO-15 package, same VBR, 600W rating, but VC = 25.5V @ 23.5A and RθJA ≈ 65°C/W (vs. 55°C/W) | Not suitable for automated SMT; higher thermal resistance limits power density in compact layouts | Choose only for prototyping or repair where through-hole compatibility is mandatory |
Compared with SMBJ16CA and 1.5KE16CA, the P6SMB16CH offers superior thermal performance (RθJA = 55°C/W), lower clamping voltage (23.5V), and AEC-Q101 qualification-making it optimal for space-constrained, high-reliability automotive and industrial SMT designs.

FAQ
What does the "CH" suffix indicate in P6SMB16CH?
The "CH" suffix denotes a bidirectional configuration, meaning the P6SMB16CH provides symmetrical clamping in both forward and reverse directions. This enables protection of AC-coupled signals or floating nodes without polarity concerns, unlike unidirectional "H"-suffix variants. The P6SMB16CH achieves this via internal dual-diode architecture and is marked without cathode band distinction.
Is P6SMB16CH AEC-Q101 qualified?
Yes, the P6SMB16CH is explicitly AEC-Q101 qualified per the manufacturer's datasheet (Version A2102). This certification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD robustness-confirming suitability for automotive under-hood and body-control module applications where reliability is critical.
What is the maximum clamping voltage of P6SMB16CH and at what current?
The maximum clamping voltage (VC) of the P6SMB16CH is 23.5V, measured at a peak pulse current (IPPM) of 26A using the standard 10/1000μs waveform. This value ensures downstream 24V-rated components remain within safe operating voltage limits during transient events such as load dump or inductive switching.
Does P6SMB16CH require special handling during PCB assembly?
No, the P6SMB16CH has Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and processed using standard SMT reflow profiles without baking or dry-pack requirements. Its matte tin-plated leads also ensure solderability per J-STD-002, supporting high-yield automated placement.
How does P6SMB16CH compare to unidirectional P6SMB16H in circuit implementation?
The P6SMB16CH replaces the unidirectional P6SMB16H in applications requiring bidirectional protection-such as differential data lines or AC-powered subsystems-without changing PCB layout. Unlike P6SMB16H, which requires correct cathode orientation, the P6SMB16CH functions identically regardless of terminal connection, simplifying design and reducing assembly errors.
