Product details
Overview
P6SMB16CA from Taiwan Semiconductor is a bidirectional 600W surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a standoff voltage of 13.6 V, breakdown voltage range of 15.2–16.8 V at 1 mA test current, clamping voltage of 22.5 V at 28 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the P6SMB16CA datasheet, P6SMB16CA pinout, P6SMB16CA application, or P6SMB16CA equivalent, key selection criteria include unidirectional/bidirectional configuration (CA = bidirectional), DO-214AA (SMB) package compatibility, 600W peak pulse power rating, low leakage (<1 µA @ 13.6 V), and ISO 7637-2 compliance for automotive transient immunity.
Technical Context
The P6SMB16CA implements a glass-passivated silicon avalanche junction optimized for fast response (<1.0 ps rise time from 0 V to VBR min) and stable clamping under repetitive or single-event transients. Its bipolar construction enables symmetrical clamping in both forward and reverse directions without polarity sensitivity.
Thermal performance is defined by RθJC = 10 °C/W and RθJA = 55 °C/W, supporting reliable operation up to 150 °C junction temperature. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for SMB molded compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 600 W - sustains high-energy transients per ISO 7637-2 Pulse 1/2a/2b/3a/3b without failure |
| Standoff Voltage (VWM) | 13.6 V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 15.2–16.8 V @ 1 mA - guaranteed avalanche initiation window for predictable clamping onset |
| Clamping Voltage (VC @ IPPM) | 22.5 V @ 28 A - limits downstream voltage during surge, protecting 24 V system ICs and MOSFETs |
| Reverse Leakage (ID) | <1 µA @ 13.6 V - negligible standby power loss and minimal impact on high-impedance sensing circuits |
| Junction Temperature Range | –55 °C to +150 °C - supports operation in under-hood automotive, industrial SMPS, and outdoor power adapters |
| Package | DO-214AA (SMB) - industry-standard surface-mount footprint with matte tin-plated leads, J-STD-002 solderable |
Pinout & Package
Package: DO-214AA (SMB), bi-directional configuration - cathode band marking not applicable; terminals are non-polarized and function identically in either orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals serve as interchangeable surge current entry/exit points; no polarity dependency in bidirectional mode |
| Case (body) | Thermal and mechanical interface | Plastic SMB body provides 10 °C/W junction-to-case thermal resistance and UL 94V-0 flame retardancy |
Key Features
| Feature | Design Value |
|---|---|
| Fast transient response | <1.0 ps rise time ensures clamping activation before sensitive circuitry experiences overvoltage stress |
| ISO 7637-2 compliance | Validated for Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) in automotive ECUs |
| Moisture sensitivity level | MSL Level 1 (per J-STD-020) - no bake requirement prior to reflow, enabling direct SMT placement |
| Halogen-free construction | Complies with IEC 61249-2-21 - eliminates brominated flame retardants for RoHS-compliant end-product certification |
| Low clamping ratio | VC/VBR ≈ 1.34 - tight voltage margin between breakdown and clamping improves protection headroom for 15–24 V systems |
Applications
| Automotive Body Control Module (BCM) | Industrial Switch-Mode Power Supply (SMPS) |
|---|---|

IC Role / Device Role: Bidirectional TVS array (using discrete P6SMB16CA per line) for common-mode and differential transient suppression. Use Value: Symmetrical clamping ensures equal protection regardless of plug orientation; 1 µA leakage preserves USB suspend current budget. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA (Bourns) | Same DO-214AA package, identical VWM (13.6 V), VBR (15.2–16.8 V), and VC (22.5 V); rated for same 600 W, but higher typical IR (2 µA @ VWM) | Validated in Bourns' AEC-Q200 qualified portfolio; preferred where automotive qualification documentation is mandatory | Select SMBJ16CA when AEC-Q200 compliance evidence is required; otherwise P6SMB16CA offers equivalent electrical performance at lower cost. |
| 1.5SMC16CA (ON Semiconductor) | Same electrical specs and DO-214AB (SMC) package - 2.5 mm wider body increases thermal mass but requires PCB layout change | Higher Ptot (5 W vs. 3 W) supports longer surge duty cycles; used in telecom power interfaces with sustained fault conditions | Choose 1.5SMC16CA only if board space allows SMC footprint and higher steady-state power dissipation is needed; P6SMB16CA fits tighter SMB layouts. |
Compared with SMBJ16CA and 1.5SMC16CA, the P6SMB16CA delivers identical clamping performance in the smallest standard SMB footprint, with lowest leakage and full ISO 7637-2 coverage - making it optimal for space-constrained, cost-sensitive 12–24 V systems where AEC-Q200 is not mandated.

FAQ
What does the 'CA' suffix indicate in P6SMB16CA?
The 'CA' suffix in P6SMB16CA denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage clamping in both polarities without requiring orientation-specific placement. Unlike unidirectional variants (e.g., P6SMB16A), the P6SMB16CA has no cathode band marking and functions identically regardless of terminal connection order - essential for protecting AC-coupled or differential signal lines where polarity is undefined.
What is the maximum clamping voltage of P6SMB16CA under surge conditions?
The maximum clamping voltage of P6SMB16CA is 22.5 V when subjected to its rated 28 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and guarantees that downstream components rated for ≤24 V operation remain within safe voltage limits during transient events, provided layout inductance is minimized.
Is P6SMB16CA compliant with automotive transient standards?
Yes, P6SMB16CA meets ISO 7637-2 requirements for Pulses 1, 2a, 2b, 3a, and 3b - covering load dump, battery disconnect, inductive switching, and capacitive coupling transients common in 12 V automotive systems. Its 600 W peak power rating and sub-1 ps response time ensure robust immunity without additional external filtering in BCM, lighting, and infotainment subsystems.
How does P6SMB16CA compare to unidirectional P6SMB16A in terms of leakage current?
P6SMB16CA exhibits the same maximum reverse leakage current specification as P6SMB16A: <1 µA at its 13.6 V standoff voltage (VWM). Both variants use identical silicon die and passivation processes; the CA suffix adds no leakage penalty. This low leakage preserves battery life in always-on automotive modules and avoids signal integrity issues in high-impedance sensor interfaces protected by P6SMB16CA.
What is the thermal resistance profile of P6SMB16CA, and how does it affect PCB layout?
P6SMB16CA has a junction-to-case thermal resistance (RθJC) of 10 °C/W and junction-to-ambient (RθJA) of 55 °C/W under standard JEDEC conditions. To maintain TJ ≤150 °C during repeated surges, PCB copper area under the SMB pad should exceed 40 mm² with ≥2 internal ground planes - ensuring heat dissipation aligns with the device's 3 W steady-state power rating and prevents thermal runaway during burst-mode operation.
